“ 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...” --Roller
“ There has been a lot of talk lately about affordable portable amps. Coming from using high end portable amps in the past I was quite skeptical. I thought that there is no way a sub 200.00 amp could compete with RSA and Headamp. I had the same mentality towards portable amps as I did towards customs. I guess I thought that if you could not afford the big boys then you really did not...” --chef8489
“ Have tried many headphone DAC/Amps in the £50 - 200 range and nothing comes close to the resolving, enjoyale nature of this bit of kit. Western manufacturers should take note. Quality, performance and a great price point can all exist together! :) Had mine for almost a year now and have no intention of letting it go... ” --Krisman
“ I purchased the Nuforce Icon HDP along with Sennheiser HD 650 headphones as my first desktop setup about six months ago. I'll start off by saying that the HDP has been a fantastic purchase that I am thrilled with and enthusiastically recommend, especially as a starter desktop setup. The HDP has loads of power and easily drives my Sennheiser HD 650s and other high impedence...” --Sid-Fi
“ iFi Audio is a new comer in the headphone amp scene, but it does share the same bloodline as the renowned U.K. based premium audiophiles brand AMR. While AMR already has some top end gears to offer to the speaker and full rig owner, its little sister brand seems to aim toward mainly the computer based headphone user as well as minimalist audiophiles. Their current ‘Micro’ line of devices...” --ClieOS
“I'll make this a short review and just make several points. - Excellent unit for beginners. You can use it so many ways, it's really an all-in-one. - Build quality is great, I haven't heard of any dead units. Some minor problems here and there but they are quickly resolved. - Superb support from the company. Fast and helpful emails. - Upgrade and resale potential. You can use this as a DAC...” --_Spanky_
“ I bought this amp for my Q701s (Which I won't receive until Friday). When it came I took it out just to make sure it works (All my current headphones are low impedance and don't require an amp). I hooked it up with probably one of the worst possible sources you can imagine: a Nintendo DS (I was in the middle of playing a DS game when it arrived). Of course there was volume, but I also almost...” --DSW92
“Received new FiiO E7 today from Micca in Fairfax, Va (hi ex-neighbor - used to live in Arlington.) Did much reading on this forum and other reviews and truly appreciate the candid and (sometimes) brutal thoughts of recent purchasers. After just a few hours experience, can only share my first impressions - all of which are positive. Unpacked, reviewed instruction sheet, plugged in USB...” --TomT
“ REVIEW – Schiit Audio Valhalla Tube Headphone Amplifier What Sort of Schiit is This? I read, as did many of you, the head-fi threads about the very popular and attractively priced Schiit Asgard. But to be quite candid, I personally had about as much interest in an inexpensive solid-state headphone amp as I did in weeding behind my garage. As such, I have never heard the...” --Skylab
