@no_regrets I've been moving gear around and was demoing CD players and transports, so the Jay CDT3/3 was there just because. It'll be too shelf eventually.
Speaking of transports the Teac VRDS 701 is stellar and I have the CG-10 clock and like it more then the Jay. DAC is excellent, preamp functions as well make it a better value.
The DAC200 is great and again preamp functions as well make it a great value all around, but I love above all else sound stage depth and expansive music rendering. The Aero (Tung Sol 1945 6SN7) is excellent. To my ears detail isn't lacking compared to the DAC200, but the sound is much "larger" front to back and side to side, and I'm not embellishing this when I listen to my headphones with the Z10E and Aero, I'm literally looking over my shoulder sometimes hearing an all encompassing and 3D soundstage like nothing else I've heard before. It's just incredible (Meze Empyrean 2 and pure silver cable). The Aero has a little less snap and immediacy compared to the DAC200, but I sold the DAC200 and the Aero is my dedicated headphone DAC.
I just got the Grimm MU2 and waiting the Matrix Audio MS-1. I have the Mola Tambaqui, which I love, but I'm really interested in DAC's as of lately it seems. I want to get my two systems flushed out and then maybe look for tube Monoblocks.
