“ 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
“ I did buy this amp to see if it really can beat expensive amps. Well, it plays nice, but does not even play like 300$ amps. Nice to have as an experience, but not as a final word in system. ” --Synthax
“ The GOOD: -- Size: very small and pairs well with a J3, iTouch, Sony X-Series, iPod Classic or similar device. -- Battery life: as said before, simply amazing! -- Construction: very solid and well built. Great switches, with a firm feel and nice "click" to them -- Form Factor: Second to NONE! All of the inputs, outputs and switches are perfectly placed. --...” --SoulSyde
“Pre-Ordered from Oliver (EA) in Oct(?). Received the unit about 2w ago. The bad The volume pot tracking is not very smooth (catches a bit on some positions (tactile feel, not audibly)). (will check whether pot knob gets caught on the case) (edit: yep, that's it, no real quality issue there) To my surprise, the unit does not come with a 2RCA->3.5mm or 3.5mm to 3.5mm .I only had a fairly long...” --svyr
“ 3 of the 5 cables it shipped with failed within days. The distributor replaced with an L cable of surpassing quality, but soon after that the damn thing stopped working altogether. Shoddy workmanship all around. Highly disappointed. ” --Ninjacello
“ Can be purchased from Top Dog Headphones if in the UK like me. Here is my review http://www.head-fi.org/t/630020/review-digizoid-zo2-3-personal-subwoofer-portable-headphone-amplifier-review-true-power-of-bass ” --Swimsonny
“ This review describes version with OPA209, but other ones should perform on par or better and probably without GSM noise issue. The amplifier is powerful enough to drive power hungry headphones such as orthodynamics, but also has very low impedance for balanced armature IEMs. DAC, while very good, is not the absolute benchmark - but that is to be expected in an integrated device....” --AstralStorm
“ Love the brushed metal feel to it, cricri+ brings it's dac up to 24/96 ” --noobandroid
“ I'm really impressed by this tiny little amp. The C&C BH is truly a portable amp, hardly bigger than a tube of chapstick and boasting an insane battery that supposedly lasts 60+ hours. I've not yet charged mine since opening it a few days prior to this review and it's still going strong. The BH also has smart charging, so when it finally does run out of juice, you don't have to worry...” --pngwn
