Is there any audition for this thing?
Would love to try it cos so many good review...

I wonder if I will be impressed as I dont find heavily modded Zhaolu (YuHeng's) impressive...

Either way lol, that's a very very long connector and most opamps benefit for having a short path, plus if the HDAM is a BJT input, you're generally inviting distortion, instability and lowering CMRR, even for a JFET input, that's quite a stretch. Snipping is recommended.

When mounting opamps, expecially BJT input ones like the LM4562, try not to use even a socket if possible, and decoupling using a film cap with as short as possible leads between each of the supply pins will give you really really good sonic returns. Sometimes even an extra centimeter of wire along the feedback loop can cause the opamp to b****.

will wait for master chua advice.....new opam or hdam? brows.gif
chua, i'm going to jw marriot tommorow, right after they open the "gate". will only bring rm 200 without credit cards. whistling.gif

I suggest we wait for coming soon discrete opamp for one more month, if things wont come out, we only conduct a bulk of HDAM, I will keep on tracking with the designer, no worries smile.gif

Sorry GodLuvSxs, Not going join this HDAM bulk this round , I already have HDAM in my old cheapo marantz CD63SE.

I am no master or sifu, just another kung fu panda trying to learn audiophile.

Morning will be less exciting, due to vendor seting up the system, or the vendors just start to move in. afternoon might be better
gatevalve
morning i will be "snaking" at mr khwang's place to listen to cec cd 3300, arcam alpha 9 amp and epos es 14 combo.afternoon need to be home for people from desa low yat to look into my av receiver problems.
chua, maybe i go on saturday after some shopping with my wife. brows.gif

Hi Abel,

Anywhere to get an used zero dac ?

Thinking of bulk order, but taking too long to wait.

Hi bro gatevalve, you wanna take cdp + amp from there? thick pocket u have laugh.gif
How many amp you would like to audit? Can i go to check out when u audit? Just wanna listen how different the characteristic between Audiolab and Rotel with other amp.
Last time the owner told me Arcam Delta 290 is good also, but i heavent went back to audit with my own speaker and players.

OT. Just my 2sen.

I always look for used amps that have the pre out and main in , whereby I can upgrade at later stage like partnering with SS power amp or tube pre amp.

I think most Audiolabs have this function, not sure about Rotel .

I am still at entry level, so offence to all.

gatevalve
hi all,
went to smart home solution.tested cec cd 3300 and marantz 5001 with and without zero dac.
soild state amp used, arcam alpha 9.
then tested old school pioneer pd s802 cd player.
we used epos es 14 during the test.
the winner...according my ears....pioneer cdp with zero dac(c/w opa 627).
cec 3300 is a good cd player.it just a matter of preference only.
marantz cd 5001 with dac......too forward and bright
cec 3300 with dac......too polite
pioneer pd-802 with dac....in between the above tast, good bass,smooth vocal and ngam2 high rclxms.gif

i will keep this zero dac for sometimes ...rm 400 and very keng this dac.
looking foward to audit nad 541 before i make any purchase.

for amp.....still dunno which solid stae amp to get.most probably audiolab biggrin.gif

cheers.
rey.

tomorrow will go to jw marriot.

Just back from KLIAV.

The most unforgetable event, the KEF LS 3/5A.

The second most unforgetable sound, Harbeth SHL 5.

Others are just too expensive, and certain frequency just dont sound right.

The most interesting CD track, NIL Lofgren Live and Whitesnack live in Tokyo. (my god, isnt that whitesnake is heavy metal)

Not too crowded, just nice.

Just got the power cord (so called Asylum). From external, I know this power cord make my stock cable to dust. going to try soon.

Eh? Where did you get it from? I saw QED power cord going for 300 from 420. Was quite tempted but remember reading on What HiFi review so-so only. Then saw Merlin Tarantula and the quote was 420. Also saw Transparent cheapest power cord at 368 but with US plug. At the end, I was lazy to go back all the way up so didn't get any power cord. I was hoping to be able to audition Sennheiser HD280 Pro but nobody selling. Tried a Beyer that's about 480 but sound was so harsh.

Do they have any QED Silver Anniversary XT Speaker cables or Chord Rumor 2 ?
ijan
HDAM is really overhyped. The long cable is an antennae for TV3 & 8TV.

The OPA637 is miles better than the OPA627, but it cannot be used in a DAC circuitry since its not unity stable...sadly..the 637 denounces the 627 so bad i never use the 627 unless stability is main priority.

i will go back to smart home solution on monday evening only if nad 451 cannot tapau that pioneer old skoll cdp. nod.gif
no audiolab amp available at this moment but they have arcam alpha 9 amp.
mr khwang ask me about bulk order on new valve amp...but i,m happy with my soundstage 1.5 (c/w mullard tubes).
if you are free on monday then we can meet at smart home solution.

ot .

Can anyone plse help :-

What is the diff between soundstage one and 1.5 ? besides the remote control.

I find the vocal a bit harsh on Soundstage one , before run in ..

no la, actually some audio shop ppls are like this one ma laugh.gif
i went there kacau tht owner many time alrdy, he is quite okay la.
Got Quad 11L at tht shop, almost poison myself to pick it home. Tht Quad is 'shining' piano black finish, so tempting. Selling for 1.8k, while from other shop used one (cherry finish) is 1.6k.
320BEE i nego to RM750 smile.gif without remote, i think the price is still not low enuf lol.
sorry for poisoning.

Ultimate audio's Arcam and Audiolab even more poisoning.. anyway.

These are the power cord I ordered Volex 17604 --

First, I'll state that I do not consider these industrial, mass produced, low margin 14gaX3 shielded powercords to be an 'upgrade', but rather, they are the minimally acceptable powercords for audio use (which is why I'm posting this in the General Asylum). For whatever reasons, vendors generally provide generic 18 or 16ga PCs, and I've never encountered a situation where the Volex 17604 or 17605 (2 and 3 meters) have not produced a major improvement in all areas, soundstaging, resolution, dynamics, extension, emotion.....Simply put, everything is 'mo betta'.
These powercords are ideal for anyone who wants to judge whether powercords actually make a difference or for judging what value a more 'bespoke' and expensive cord is providing.
Comparisons - In comparison to the 'Asylum' cord, the latter provides higher resolution, which may be attributable to the removal of the plummyness imparted to the bass (in comparison to most OEM cords, the Volex bass is tighter and more resolving). But realize that a premade 'Asylum' cord will cost about 10x as much, or if you DIY, each major component, the cable, plug, IEC, will cost as much as a complete Volex cord. My own DIY starquad powercords (IMO) and many other aftermarket cords are substantially better, but whaddaya expect for <$1/ft for the whole dang cord?

If you're unsure as to whether powercords make a difference, want maximum bang for the buck, or want a cheap baseline for evaluating audio specific cords, do yourself a favor and buy the Volexs. Many electronic distributors cary them - Allied, Newark, etc...

---

However, I am disappointed it is not Belden cable as used in the Asymlum power cord. As to how much improvement, I think it does not sound clear to me, but I will just leave this power cord to the ZERO DAC. For less than RM 50, I think it barely meets value for money. Alternative is to replace the stock plug and connector.

On this topic i actually have a sound ideal here.

Worse is Better lol. Believe it or not. Now ye shall receive one of my patented dumb lectures.

Taking into assumption that you don't need a shield and have little or no radiated EMI or RFI. Being the inventive student i was, generally bored, and the kind that likes to push buttons for no apparent reason, i did some research using a time domain reflectometer and agilent power meter using 50 ohm matched souce/load combo, signal came from a really expensive Rohde and Schwartz i would love to steal.

I can't do anymore request tests as the lec that let me do this, Mr Varnes took a 1 sem holiday, that old coot. Nonetheless the results from this one are interesting.

We consider 2 cables, 1 a standard RG58 and another is a Thin Lan Silver plated Cable made by Huber Suhner

Results = Nothing out of the ordinary, the Suhner cable beat the shit out of the nameless RG58, by a good 30-40 percent marging in attenuation up till 500Mhz and after that it went up to 100 percent.

But it did get me thinking. Attenuation at specific bandwidths might be useful, it's a just a bad thing made good by using it in a place where it can help. Attenuation at 60Hz was obviously so small it didn't matter, generally only after jumping to 1Mhz did i see the difference between cables. But what about the rest of the range? All those megahertz must mean something right?

Haha, that's where it all came in.

What do we want from a good power cable?

1) For it to deliver power at a given frequency with the lowest attenuation.

At 60Hz, this doesn't matter, both mathematically and practical test wise, as long as you have a cable that can carry the current, it should never matter)

2) For it NOT to deliver any power at any frequency aside from from the fundemental.

You see, as the frequency rises, the crap cable generally puts up more of a fight to the signal than a good one. This is bad in RF applications, but when all you want is 60Hz, then the reduction of all the junk high frequency signals that travel along the cable is awesome. Awesome Possum.

A good cable generally tries to model a pefect transmission line as closely as possible, a bad cable doesn't. A bad cable has higher levels of resistance, capacitance and inductance, although unwanted in the signal domain, in the power delivery domain, it acts as a low pass filter that filters out crap before it reaches your PSU.

Conslusion/TL/DR : Cheap and crappy cable is potentially far better than expensive cable. As long as your cable is shielded, a crappy cable should always beat a good one when used as a power cable. Yay.

Someone blanja me when i come back in December ya?

You see, as the frequency rises, the crap cable generally puts up more of a fight to the signal than a good one. This is bad in RF applications, but when all you want is 60Hz, then the reduction of all the junk high frequency signals that travel along the cable is awesome. Awesome Possum.

A good cable generally tries to model a pefect transmission line as closely as possible, a bad cable doesn't. A bad cable has higher levels of resistance, capacitance and inductance, although unwanted in the signal domain, in the power delivery domain, it acts as a low pass filter that filters out crap before it reaches your PSU.

Conslusion/TL/DR : Cheap and crappy cable is potentially far better than expensive cable. As long as your cable is shielded, a crappy cable should always beat a good one when used as a power cable. Yay.

Someone blanja me when i come back in December ya?

It sounds like one needs to be an engineer to enjoy the music ( sorry, I am from financial school ).

The bottomline is which power cord, or brands you recommend ?

For me, Volex is better than pc power cord, as Chua said. I have one of Volex.

I do agree that expensive power cords are poisonous , so it is better not to touch.

Sorry, No intention to flame you.

Nah, i myself am using a laptop with it speakers to enjoy my music, doesn't matter if it distorts like hell, clips at the best part of the song and generally sounds like a puking monkey, i still turn it on and enjoy. All i miss are my lossless classical music collection sad.gif

Hard to recommend brand names as i wouldn't know, i usually just build my stuff. But i can give you criteria.

- Should have good shielding
- Copper quality should be low
- Dielectric should be crap

I'm not saying one can hear the difference, but for all means and purposes a cheapie Volex Shielded cord should beat a custom made Suhner in the power role. tongue.gif

Thank you for sharing your valued information.

Very good advices indeed.

I am supposed to look out for better cords, your words are of right timing.

Please spend some time reading this..

http://www.audiocircle.com/circles/index.p...6&topic=50799.0

Please note in the review, the Volex (RM 50) is pitted against such cable as Harmonic Tech AC11 (single crystal copper) RM 600, Tsunami RM 1100, and other $$$ cables.

Bob has written the review above. The guy who diy the Asylum power cord has ventured into making his own power cable, if not wrong, it is VH audio. Should sound quite familiar.

My ears are trained to good power cords. I was poisoned by this Transparent Power link plus and I could discern (Blind fold wont fail me I bet). On the instance of Volex, I have to place my ears inside the speaker.

I understand the fundamentals of RFI and EMI and how that gets transformed and go into the signals. For the system to sound, the AC source that comes out from the plug (red) has to returned to where it came (black).

Therefore every every component in the AC source, right up to the speaker and back is important.

Since I dont have ZERO now, I would wait to see if Bob's comment on Volex hold water when the dac comes.

empire, u are wanted in the ZERO dac section, u could be the new opamp to the better sounds.

Do they have any QED Silver Anniversary XT Speaker cables or Chord Rumor 2 ?

Not too sure but CMY had a huge range of QED cables. Don't remember seeing Chord.

These are the power cord I ordered Volex 17604 --

First, I'll state that I do not consider these industrial, mass produced, low margin 14gaX3 shielded powercords to be an 'upgrade', but rather, they are the minimally acceptable powercords for audio use (which is why I'm posting this in the General Asylum). For whatever reasons, vendors generally provide generic 18 or 16ga PCs, and I've never encountered a situation where the Volex 17604 or 17605 (2 and 3 meters) have not produced a major improvement in all areas, soundstaging, resolution, dynamics, extension, emotion.....Simply put, everything is 'mo betta'.
These powercords are ideal for anyone who wants to judge whether powercords actually make a difference or for judging what value a more 'bespoke' and expensive cord is providing.
Comparisons - In comparison to the 'Asylum' cord, the latter provides higher resolution, which may be attributable to the removal of the plummyness imparted to the bass (in comparison to most OEM cords, the Volex bass is tighter and more resolving). But realize that a premade 'Asylum' cord will cost about 10x as much, or if you DIY, each major component, the cable, plug, IEC, will cost as much as a complete Volex cord. My own DIY starquad powercords (IMO) and many other aftermarket cords are substantially better, but whaddaya expect for <$1/ft for the whole dang cord?

If you're unsure as to whether powercords make a difference, want maximum bang for the buck, or want a cheap baseline for evaluating audio specific cords, do yourself a favor and buy the Volexs. Many electronic distributors cary them - Allied, Newark, etc...

---

However, I am disappointed it is not Belden cable as used in the Asymlum power cord. As to how much improvement, I think it does not sound clear to me, but I will just leave this power cord to the ZERO DAC. For less than RM 50, I think it barely meets value for money. Alternative is to replace the stock plug and connector.

For that price, I can replace the cord for my Audiolab and also the Zero! Thanks for sharing as always ccschua! BTW, don't these electronic distributors carry the Belden used in Asylum power cord? If not, I'm sure they can be found in Singapore...

CMY had QED Silver Anniversary XT Speaker cables (3m with gold terminates both ends):
single = RM495
bi-wired = RM950 ohmy.gif

In fact, their air lock plugs are more expensive than the wire, about RM 35 /unit.

Normally, I just buy the wire, and buy cheaper plugs outside. Most people also got a few sets of wire, so I prefer not to terminate the plugs, than terminated plugs.

But if there is a special offer, then may be worthwhile to buy together.

Bi-wires does not really help with an entry level amp, Bi-amps might do. A lot of arguments over this area.

It is just a personal preference.

Beldon cable or Wire, u can get it from multidata at old klang road near kampong datuk harun, but I not sure this company still exists now. I got my beldon 1694A & 46381 cable and canere crump plug from them many yrs ago for my 1st HT system.
andrekua
46381... I used before for car audio.
I think if not mistaken is 10AWG (or was it 12AWG).
1694A is used for RCA cable but I still remember KF Audio staff told me its more tv use for coaxial.

ohhh u got visit Uncle Liew also smile.gif
yeah u are right bcoz those cable is 75ohm is coaxial or digital cable RCA is 100ohm

is depend Bi-wire i means ur amp got 4 out-put if 2 channel Bi-Wire wont help

bi-amp the sound will be smoother if ur amp not enuf power Bi-amp not recommend smile.gif
bcoz normally Bi-AMP the power only half means ur amp rated 40w RMS x 2 means u bi-amp is 20 RMS x 4

I dont remember liao who is Uncle Liew.
I went there once for installing HU and 2nd time for wiring the amp.
I quit 6months later after the blardy immo salesman show me how to steal my wira (with anti theft mod) in less than a minute and also started the car. I was stun beyond belief.

46381 a bit hard to find liao. Lastime I forgot who I bought it from in the famous ICE forum. Now Im using 5100UP which is a bit cheaper. 14AWG copper wire cost around RM8/m from Jalan Pasar. Also bought Belden 8760 for RCA cable. I think 8760 is slightly better than Canare L4E6S. Canare cable make my speaker sound bright.

They ( CMY ) can loan me the wires, interconnects, speakers and amps to go back to try first ( kenal poison again ).

So , got to buy something in return, Malaysia culture.

If I buy from UK and later on if I find that it is not suitable for me , than I have to keep them in the cold storage.

@Abel,

You are using tube pre amp, right ? Do you have hum noise coming out from the speakers.

I am using AntiQue tube pre amp, I got this hum noise. When I try my Soundstage as pre amp, I hear hum coming fr speakers too.

Any Solution ? Sifu.

u should total silence. Even when u soundstage volume turn to 3'o clock, u should still hear Nothing.

if your AntiQue got sound, first u have to make sure where the hum come from. Bring your amp to some one system that is totaly quiet, to confirm if the sound is from the amp.

next .. u have to mention your setup. noise can come from RCA as well.
