Most satisfying system change in 2017?

The only change in my system was to build a DIY Ultrasoinc RCM, cleaning every LP I own, and enjoying vinyl playback like never before. And, it only took $200 or so in parts, and works like a champ.

One of the best improvements in forty five years in audio.

Happy New Year,
Dan

bar81 / That was totally uncalled for. Just saying...

Added an Ayre K-5xe(mp) preamp.  Definitely improved my system.

Atma-Sphere MA-1, and MP-3, Vandy Treo's, converting McCormack DNA-1's into monoblocks, Equi+Core 1800(just installed).

It's been a busy year.

Roon, Roon DSP and Tidal. Great combo!
