Hey guys, I need a bit of advice on the title of this thread. I just purchased the ATH-A900x from Audio Technica, and I have the Creative ZxR sound card installed on my PC. I use the headphone out for the headphones, but I would be very interested in (possibly) getting more sound quality if possible: I have researched that the ZxR has an output impedance on the amplifier of 10 Ohms. The recommendation is for the headphones impedance to be at least 8 times more than the output impedance of the amplifier, which in this case, the headphones have an impedance of 42 Ohms only. This is the reason why I am considering, instead of using the headphone out, purchase the Schiit Magni, and use the headphones through the ZxR's RCA ports Basically: ZxR > RCA Out > Schiit Magni > Headphones I would also like to keep the surround effects and other features. I intend to keep using the ZxRs DAC which I have read is quite decent for the price range. Any thoughts? Do you guys think that the Schiit Magni with its sub-ohm output impedance will be better to drive these cans? (The Magni has 0.2 Ohms) Do you think I'll see any improvement in sound quality? Thank you so much!
