“ WASAPI----->Bitmatched/Perfect transport----->Maverick D1 RCA SS output------>Matrix M-Stage(Stock)----->AKG K-702 I use these with my AKG K702 headphones and there really isn't much to say. My previous amp had no problem powering these bad boys either but it hissed and popped at the volumes necessary to do so. With the dip switch on the bottom controlling level of gain...” --ninjikiran

But, teamed with a pair of rounded/smooth headphones like the HD650s, it makes a great entry level combined amplification and DAC...” --gogogasgas

And a big step, at that – the Mini-Portable is priced at $349, where there is a lot of heat in that...” --WoahReQQuiem
“After spending a lot of time with some high quality tube amplifiers, I thought it was time to revisit the world of solid state (using sound processing chips rather than tubes). Some headphones seem to pair well with tubes while others like solid state so it's always nice to have both options available. The amp I decided on is the Matrix Quattro amplifier which offers balanced and unbalanced...” --Loquah
