Go-vibe V5 or PA2V2 for ATH-EC7 and HD595??

[shw24]

Hi Guys,

I need advice on whether to get Go-Vibe V5 or PA2V2 to be match with ATH-EC7 and HD595 if I can get almost the same price for V5 used and PA new.

Well, I just bought the ATH a week ago, and while I like the mid and high, but it lack of bass. It is there, but sometime, I just want to have a little bit more and deeper. But well, I cannot complaining about the earbud, but maybe there is someway to improve it, because now I'm away for several months, and have to seperate with my HD595 and some home system, and have to relay on my nano and the ATH.

Anyway, can you please tell me how the EC7 will be if I put amp on it? is it will be much better or not improve that much? and how about the HD595 as well?

Thx guys. Geez, I never able to leave this forum. When I got assign to go for projects, I'm suddently eyeing on the EC7 and luckly, someone selling the used, one almost never been used before for cheap... no second thought...Grab it and now it is screaming for amp.... not cheap anymore then.

I must admit I never heard the two, but what I hear about their internals, I would strongly suggest the Go-Vibe. The PA2V2 contains an all-in-one headphone driver which requires a huge electrolytic cap after it's output because of it's high dc offset. Well, maybe that doesn't help you, but the point is: electrolytic = bad sound.

The Go-Vibe on the other side, has normal audio opamps in it, which are considered to sound a lot better, plus they don't need electrolytic caps in the signal path. I don't know if I heard that correctly, but some models of the go-vibe 5 contain the ad8620 opamp, which is said to be one of the worlds best opamps.

The only audio op-amp that can satisfy HD595's current hunger is AD8397, second best - BUF634 at the front of a good "normal" op-amp, i.e. AD8620. PA2v2 would be a missed shot. I dunno the Go-Vibe schematic but the best (but not perfect) popular portable design is PINT IMHO. I would alter some details but it's low noise version could fulfil HD 595's requirements. I would use bigger electrolytic caps in first place, second: remove caps from the voltage divider.
