After some advice...
I currently have AD700's running from my PC via optical to a Pioneer VSX-521 receiver.
I'm planning on upgrading to AD900x's.
What do you guys think of my current "source" situation? Is running this pioneer entry level receiver a better option than using say a soundcard like ASUS Xonar Essence STX or external DAC/AMP like fiiO e10 or schitt combo? Willing to spend up to $200 on a source if its a decent upgrade.
I'm using the VSX-521 receiver because it is also powering my floorstanding speakers and sub and i just plug my headphones into the front headphone jack. But i guess i could easily add a soundcard and switch between outputs in windows or something if it would make my AD900's sound better.
any help much appreciated, thanks.
