Well between this thread and the other giant one, you guys have convinced me to pull the trigger on the DX-90. Thanks...I think, LOL! " src="http://files.head-fi.org/images/smilies/tongue.gif" />
My home rig is a recent-model Audio-gd NFB-28 with the TCXO upgrades (new hi-res/DSD-capable USB driver) paired with Beyerdynamic T1 balanced, but I also have a SE adapter, so I'll compare to that setup and also try the T1's with the DX-90 and see how they go. I also have the Grado SR-125i and Beyerdynamic DT-880 250-ohm to try.
I'm enjoying my T1 plugged in straight to DX90. I'll be curious to see your impressions.
