Best audio purchase of 2011


Let us know what was your best purchase this year.

I will start, found from a local dealer the Krell combo: Reference 64 DAC with the DT-10 transport. for those who are skeptical that ancient digital technology is easily surpased with new stuff, listening to this combo changed my mind. This was one of, if not the only piece of equipment which after trying out, and then reading the Stereophile review, i actually heard and agreed as to what the reviewer was raving about.

I guess the best purchase of 2011 would have to be the only major purchase I made last year, an Audio Research DAC8, It's the most musical component I own, and seems to have effectively removed unwanted digital artifacts.
Not a purchase, exactly, but an upgrade of Zu Definition speakers to MKIV status.
Cary slp-50b tube pre. Did exactly what I wanted, warmed up my amps to the point of heavenly.
I am in a position where my system is pretty balanced. If I change I need to upgrade everything. No way I can afford that, or want to, I am happy with what I have.

That leaves tweakery and I picked up 2 second hand Nordost QB4 units over the year. I can't explain it, but an immediate real improvement, with the first making more difference than the second. No way do I think the material content justifies the new price, but second hand, cetainly
