I am using a Schiit Yggdrasil DAC and love it. I have a Schiit Vidar amp but it does not measure up to the Pioneer M-22 so I am selling it. I just need a "reference" preamp and I think I am done playing with components and I can concentrate on listening to music instead of components!
porscheracer,

Smart move!  Don's KT88 just arrived but I still have 4-6 weeks left for my preamp to be built.  Everyone I've spoken with that owns his equipment raves about the sound.  Speaking with Don sealed the deal for me.  

Congrats!

Congrats ! you will like it , the pre-amp continues to delight me ! very happy with it , will be sending it back to Don for Certain upgrades , but even without those upgrades it sounds wonderful with my SS Amplifier
What upgrades are you getting done and why? 

I still have time to make changes to my order so I would like to hear what you are thinking!
