Ah.

The reference pair of headphone I assume? It was tested with the HD580 primarily.

It generally generates a smooth, slight warm sound signature, with a musical presentation to it. Significantly, soundstage depth and width is very much improved, especially what we can see by pairing the Secret Amp with the Grados/Alessandros. Just so that you know too, it can push up to 600ohm, has two modes of playback (one gives a more aggressive, fast attack and the other more warmth, smooth), a hardware crossfeed and optimized charging capabilities, in which the circuitry is made to optimize battery charging for long hours. (aka put in the charger, leave it there for 24/7)

ah , wish to try them with my ER4

the first time i listen to this amp, i noticed that this amp gives a good separation between vocal and the background instruments

I really like the Secret Amp, no regret, simply awesome for such a highly portable amp! However, my preference might be difference from others. So far, I actually prefer low gain with secret switch off and with the crossfeed turned to minimum for both of my very efficient headphones. I don't have high impedance headphones to try the secret switch and crossfeed yet, so, I can't comment that I prefer the secret amp with high gain and with the secret switch on nor playing with the crossfeed. However, with everything turned off, I really thrilled with the performance and the purity of this tiny beast, simply awesome!

Bro pcwork, I will be calling you bloody regular till I find an Ipod 4G and modded into pcmod.

***..
hahaha
just now i was running some air compressor and some machinary couldn't hear any phone call...
though give u a call back after i bath and dinner. lol.

Wow! I never have a clue that this was made in Malaysia, the high cosmetic build suggest that it is from the states like other headamp. Congrats!

I'm currently looking for a portable amp as well to drive my K701, AHD2000, E500, Koss KSC75/PortaPro/SportaPro. Does this amp have the synergy with my rig?

When I am back from my hometown we could meet for an audit.
For all I know, the KSC75 sounds darn good on the Secret Amp. Hmm.. Hopefully next week I can grab my recabled KSC75 then see how far the difference is.

PS: PcWork, if yuheng drops by your place before I grab the KSC75 you can pass it to him too. Cause I'll most likely drop by yuheng's place next weekend also. Hehe.

Hi
srry for all of the delayed.
we been using most of the brand for reference when we built the amp.
The sound tuning parts was processed for more than 5 months.
it paired extremely well with all of the middle range headphone. like Ms2i,HD650,DT990, also some higher range headphone, like Darth beyer.

we been using Sennheiser, Beyer, Audio Technica, Alresandro AKG for headphone signature tuning.
as for IEM, we been using UE, Westone, Crossroads, Ety, kplisch, Jays, and etc.

there is no reference amp being used as comparison, coz as far as we are concerned, the amp sound better than / on par with any amp when we are comparing with other amp.

We been compared with The Hornett, Xin Reference, Iqubes, Pico and predators...and etc.
As for its special point, it have a signatures switchers, where u can get both signatures within the amp.
Also, the amp is pushable from 16phm to 600 ohm.


I hope my reply answer ur question. Thanks

whoever have enough experience auditing what sounds nice and what sounds bad, will definitely find that Secret Amp is really a good sounding amp! Just try it, and you will know...........

u banyak kena poison ah...

Not so much from my Secret Amp, indeed, pcmod more poisoning

Bro, I think I manage to get an Ipod 30GB by Monday, I will let you know, and hope you can help me mod it before I go China on 20th June!

after reading yuheng post , i think i also kena this secret poison edi

I got secret poison too, I never tempted to buy amp before... need full review to complete the poison. Walabies, you got my PM?

just directly go for listening it better than review... while other ppl taste unnecessary similar with yours.. right?

since enigmatic is going to have a small gathering for it.

anyone wanna me help buying PK2 in China? Please do let me know, I still can help few more guys. The converted price from China I can get is RM160, please do let me know and I will provide my bank in detail! It is an awesome earbud to get! Act quick, am goin off on 20th June!

Bro pcwork is in my buying help list too.

better buy now. don't regret later.
lol
10 out of 10 ppl heard my pk2 all kena poison.
lol

Wah so "kua chiong" 10 out of 10 kena poison

haha i am also kena poison by his pk2 paired with his home made amp

PcWork can you make a short comparison between PK1 and PK2 ? don't need to be long, point formed also can

because the price differences between PK1 and PK2 is far apart

bro, PK2 is RM160, buy lar, PK1 is RM490, can buy a good full size can or many famous in ear or earbud, not that worth to me ler.

i not sure either my pk1 is burned in or not.
however. channel separation and soundstage still a step better than pk2.
but pk2 is much forward. everythings slam in your face type. good for blasting some music.

it is true, but RM500 is not cheap ler
