Finally i got the internet connection and see how you guys' unit performing! Currently surfing at CC while waiting for GF to finish facial biggrin.gif

utellme: Sorry for unable to provide pictures about how to sweep opamp correctly cos of no internect connect at my staying place until I back to my home biggrin.gif Hope that any kind soul here able to provide you the desired picture!

I think you guys should let the stock opamp burn in for at least 100 hours biggrin.gif I'm planning to get the LT1364 opamp directly from LT head office, the sample unit is too darn hard to get, estimate cost should be RM20 each, should be quite worth the money. Wait till bro kwekeugene review his unit with LT1364, see how well it sounds biggrin.gif

Somes prefer LT1361 over LT1469 and LT1364. rolleyes.gif But again, it's very subjective. nod.gif

Currently no money for Zero. doh.gif But I do have 2 brand new LT1361 lying down somewhere inside my room. brows.gif

QUOTE(utellme @ Apr 1 2008, 10:29 AM)
Form the link, it seems that people tend to hv different opinion of the opamp swapping and there is no right or wrong, as it's very much matter of individual musical preference. but I don't mind to try out LT1364 just for RM20 if GodLuvSXS can get that for us.
*
Well, actually I'm pondering whether to get LT1361 or LT1364, the LT1469 should be ruled out cos it sounds quite bright compare to those two, maybe I pay bro BSOD to ship over one of this LT1361 to bro Kwekeugene do a A-B review since he got the LT1364, maybe he would get poisoned biggrin.gif Last time I seen one review between OPA2111 and LT1364, the LT1364 comes out as a more all round performer, I think it's quality should be around OPA627 lvl biggrin.gif

EDIT:
QUOTE
The LT's are ok. The 1361s have very nice mids but they lack transparency highs and bass. The lt1469 is insanely detailed but lacks mids and base. You will the most minute details possible with the lt1469, if a fly farted in the recording studio, you will hear it, but it's really not a very enjoyable experience since it's so darn bright. The lt1364 is somewhere in between and doesn't really have any discernible stand out qualities.

- Reviewed with Sennheiser headphone, I guess I'm more on LT1364 cos I love balance sound cool2.gif

Anyway, a notice to all interested audiophile: THE SECOND BULK KICKS START!!! Please proceed to counter get yours! cool.gif

Hi guys, I just back at my own home! Last time I did inquire price from the local distributer of LT, guess what?! He charge me RM30 each for 12pcs and shipping from Singapore not included!!! I guess that's a no no!

Wow, seems like you guys enjoy the DAC very much, I'm so glad tongue.gif I guess few more days later, the stock OPA2604 will reach it's peak, that's time for opamp swapping biggrin.gif

Kwekeugene: Did you tried LT1364 on the DAC section? I'm eager to know how it's going performing tongue.gif

mADmAN: How the LME49720 fare in the DAC section? great?

I'll wrote wescal(KL) to ask about LT1364 and Lt1361 and hope they will come back to me.  Since its cheap not harm trying mah, is still not satisfy then try opa627 in the DAC section.

Hi bro, I guess you only need 1 set of OPA627 since you are stick with speaker setup, just change the OPA2604 in DAC section to OPA627 is good smile.gif I think the local price should be abit steep. Ok, I'm here officially announce a no service fees charge LT opamp bulk order.

Details:
LT1364 USD4.58/each x 3.2(conversion rate) = RM14.7 (Most balanced of the bunch, highly recommended)
LT1361 USD4.25/each x 3.2(conversion rate) = RM13.6 (Nice mid but lack of transparent high and bass)
LT1469 USD5.85/each x 3.2(conversion rate) = RM18.7 (Most detailed of the bunch but mid and bass not that great)

Shipping fees is USD34 per shipment, sorry for expensive rate cos it's the LT only settle for FeDex no other choice, let's say if total order unit is 20units, then USD34/20units = USD1.7/unit is the shipping rate, ok?

i used pc as my source..
my pc doesn't have the spdif connection so i used the convertor which i purchased from godluv as well.. my setup is like this: pc -> usb to spdif convertor -> zero dac -> ms-1
i been burning my zero for around 2 to 3 days.
i found out that, i am really really disappointed with the sound.. background noise is so obviously and i am using wma lossless which all from cd audio converted it. or i used audio cd to test as well.. background noise is real loud, overall high/mid/bass so "bad", cant reveal the feeling of that music.. so "digital"..
can anyone tell me what's wrong? is the converter cause all these problem or i need not used pc as source.. should i get a reliable cd player?.. or headphone problem? surprisingly setup of zune 30gb -> visely amp -> ms-1 is "FAR" better than the dac setup i mentioned above..

hmmmmm??
*
Emmm ... background noise is obvious, i guess maybe you try to shift the power cord's plug to another power socket, cos last time I put my Aego 2 on a power adapter with lots of plug on it ends up background noise appear, after I shift it, noise no more smile.gif And bro Andiboi , you try to make sure every single cable is plugged properly cos loose connection may contribute to noise smile.gif And did you ever tried to swap opamp? Maybe the opamp leg aint plugged in properly. I'm here to assist you to solve the problem, hope to see the result of the troubleshoot. Thanks smile.gif

hmm?..
let's forget about the noise issue.. what is your review with oem opamp and the setup that same as mine..
my short review after listen these few days, listen to like old vocal chinese song, the song is quite acceptable but the high doesn't shine, mid is weak and mostly covered by bass. listen to rock music, *shake head* channel separation is bad, when to the part that every instruments are beating and all i can say "bising" and not enjoying the music.
as conclusion: i am compromised with the sq, not the sq compromised me. a good sound quality doesn't need to be compromised.

now saving money for marantz cd5001 cd player and try to pair with this dac.

Opamps? i wonder where can i find it? my area is at petaling jaya/subang/sunway pyramid.

Thanks
*
The stock opamp tends to be sound tubey, the high certainly doesnt shine while mid and bass certainly more dominating, i guess the OPA family opamp certainly not your cup of tea, try the LME49720 I provided along, please do give the ZERO a chance before classify it as an "you compromised" unit, the LME49720 sounds more detail, fast and bass is tight. Maybe you anticipate a RM4k worth of sound in this RM400 unit, i guess that's why you are disappointed biggrin.gif

one question: do i need to burn in the opamp? i mean if i change the opamp, do i need to burn in again? cause i change to lme49720, and spending few hours to play around the opamp rolling thing(kinda fun), i even put the opa2604 to head amp or the ne5532 to dac.. hahhaa... anyway between lme49720 and opa2604, i found that opa2604 is better than lme49720. cause at same volume which is quite loud, lme49720 hurt my ear and i turn the volume down and for some reason it still hurt my ear. if the answer of my question is yes, how long do i need to burn in the opamp?
i tried put the lme49720 to dac and opa2604 to head amp, i found that at the beginning of the song(i was like WOW, really nice), after awhile i found out that it sound getting worst at the middle of the song.. lol, i wonder why?
steve, i would like have lt1469,lt1364 and lt1361 opamps.
i getting addicted by playing opamps rolling stuff.

"third times of asking: i wish someone could tell me where to buy opamps beside online?"

Thanks  smile.gif
*
Every new opamp need to burn in to reach the peak, around 50 hours it would have almost reach the peak smile.gif Anyway did you roll the opamp correctly? Every opamp got a small circle on one corner, make you follow the same direction where the default opamp at. Fail to do so may damage your unit, no joking!

Bro, i think you should only try replacing the opamp in DAC section (the big board), unless you got two same opamp then only try to swap the headamp section (small board), imagine your car one side is 15inch wheel while the other side is 16inch wheel, it would be very imbalance, an imbalance setup wouldn't gives you best performance. And a reminder for you guys, only use those double type opamp not single type opamp unless you able to browndog it biggrin.gif About the LT opamp, i think those who want should let me know ASAP, so that I could arrange the bulk faster smile.gif

I could only know the best way to get opamp is order online since i dont quite know where all those component shop and prices here are way overpriced. Bro Andiboi, if you encounter any question, please do seek for reference here first before take action, cos a slight error might damage your ZERO dac, dont be shy, just ask! I will try my best to answer you smile.gif

I think every single OPAMP need at least 50 hours of burn in to get around 80% - 90% of the sound smile.gif

QUOTE(kwekeugene @ Apr 5 2008, 09:49 PM)
After one day of listening intensively to the LT1361 in the amp section, I changed it to LT1364.  I think this will be my final setup for now.

The LT1364 is very close to the LT1361 in everything except for midrange. For most songs, I found it rather lacking at the midrange and after listening for some time, it was fatiguing. LT1364 adds on to the midrange to make listening more natural while preserving the qualities of LT1361.

LT1057 is a no go for me, too much detail is lost in music. Didn't like the LT1469 either, too much of midrange is lost. How about you guys, what setup are you using?
*
Looks like LT1364 performing quite all round, you should try it at the DAC area tongue.gif

ok, i have to start apologize my previous statement or feedback.

Today i spent 3 to 4 hours listening music(playing computer in the same time), i found out that what i listen is totally different to what i listen few days back. Everything is improved than b4, i never believe the term of "Burn-in" back then. Lol. I didn't know it can be such big different(HUGE) before burn-in and after burn-in. I really enjoy listening right now and haven't change any opamp yet(it's still all stock/oem). What i like now is the bass become more live and deep, voice become neutral than before, mid is clear and balance. Overall, it served me real well now. biggrin.gif

Emmm ... it's ok, it's usually takes time to make a doubter to become believer cool2.gif That's why I always mentioned always give around one week time for the gadget to burn in, it sounds lots different biggrin.gif

Well they are Ibasso, Yulong, Zhaolu (new version) and other DAC to compare with but it boils down to costs and the flexibility of rolling. With other DAC, any mistake in the swapping and soldering will fry the chip.  Zero is just plug and play and good play ground before one matures.

how I do the burn in, feed the ZERO with thousands of mp3 with the headphone connected .. is there other way?

I guess just keep playing music would be enough ... preferable those music with high dynamic smile.gif
