HA INFO U2 Plus USB DAC / Headphone Amp Review...perhaps the best cheap USB DAC headphone amp? - Page 3

post #31 of 36

Just a bit of info, if people end op in this thread looking at this amp.

I ended up returning mine, cause the DAC was emitting a high pitched buzz whenever connected, and the volumepot, had quite a bit of imbalance and noise. This was really bad on sensitive headphones and IEM's.

I have been eyeing this: http://www.ebay.co.uk/itm/HA-info-U2-Plus-V2-AD1852-USB-Sound-Card-DAC-Headphone-Amp-U2-/261156704057?pt=UK_AudioTVElectronics_HomeAudioHiFi_Amplifiers&hash=item3cce270f39#shId

 

has anybody had this exact model or purchased from this seller?

 

I too am looking to drive a HI 2050

I orderer that model from them,returned it as described. Seller provided fast communication and excellent service. But my experience is that it's a bad match with the 2050. Could have Been a faulty model, so you could try it out and see if it works.
