MATRIX Quattro Amp+HD600/650 Balance Upgrade Cable
Will Ship To: US, Canada
I am trying to muster some money for my upgrade to the Yulong A18, and I don't really want to have two sets of headphone amps, despite how well the Quattro has been working with my HD600 since last October. This is an extremely satisfying amp when paired with Sennheiser cans. I am only letting it go because I think the D18, which you can see in the pics I uploaded, would match better with the A18.
Notice the price includes Tam-audio's excellent HD600/650 upgrade balance cable specifically made for this amp.
