Has your system evolved in the past 10 years?

Well ten years ago I had actively biamped Maggie 3.3 with moon W3 amps Theda transport and DAC. Krell KPa phono stage an argon aurum pre amp and Linn lp12. Lashed up with transparent wire. Same lp12 now an audio research phono stage. Sonic frontier transport and DAC. An Ayre k1xe. Still lashed up with transparent wire but most of it a level or two higher. And harbeths being driven by Levinson 33 monos. I went from a McIntosh Marie tuner on the main system to a mr71 McIntosh. So a basic change piece by piece. I really liked my old system as well as my new one. They are just different presentations. I now have all tube sources on the front end with solid state after that. My secondary system is the opposite solid state front end and tube preamplifier and tube monoblocks. Both systems are fun to listen to but paint a different picture to the music. 

Big time!!

If your system hasn't evolved in the last 10 years, you likely wouldn't be spending time here. Or you're broke.

I have 7 more system than I did 10 year ago bring total system to 11. 5 system primary tube some single end I have Class a solid state and ab and have 2 digital amp one on Viking yacht. I in Japan buying big horn system now. my mind and body evolve I stronger and better look my ear more mature like 24 karat gold and my libido drive lady crazy all over world they no resist the package.

10 years? Very little remains. Only the in-wall speaker cables and amp are still in the system.
