Pros: incredible costumer support and service, sound, synergy, battery life
Cons: no crossfeed switch, usb charging circuit nor bass controls
For quite some time that I wanted to get a portable amp that could make the sound more lively, with low noise and still be able to pump enough juice to some more power hungry cans, and PA2V2 definitely suited me.
The amp was used with different gear, so I could check it was a good purchase (aside from all raving reviews) and I couldn't be happier. I listened through Philips SHP1900, SHP2000, Technics RP-F290, Pioneer SE-H33, Audio Technica M40fs, A&H XD-53 and some Numark HF125, plugged to a few computer onboard chipsets, an external Creative X-Fi, Echo Audiofire 2 and NI Audio 2 DJ. The first thing I noticed was an issue many people had, scratching and hissing while adjusting volume, but that is easily solved, just pop 2 rechargeable batteries and you're set, after they were inside the amp felt quite different, despite the batteries only suppose to serve as a noise filter. I've read people having hissing in different conditions than me, I only had that issue when using the amp without batteries, plugged to an outlet.
From all rechargeable batteries out there, I'm using 1700mAh ones that seem to last ages until the next charge.
It's good to have separate channel gain control and a bright red led to show that it's powered on.
Overall, the build quality is quite good, volume knob is sensitive at the right amount, the overall black look fits most environments. If the case was made from some metal, would give a more solid feel, specially since it's portable, but nonetheless there is no fault as it is well put together as it is.
If PA2V2 could be charged through usb, it would be perfect due to the low price and higher quality when compared to cmoy amps and Fiio E5, for instance.
It has already been said a million times before, but Gary, the guy behind Electric Avenues is helpful beyond measure and overall a great guy. Nowadays, more than ever, good customer support is quite important, and that's a thing that excels.
Great deal, recommended :)
