50 years of Mac for me.. I love it. C11-C2500. MC30-MC1.2. I kept a lot of it. It's as different as the last person that worked on it.. Their newer gear not so much. BUT you learn what sound what way.. I like Mac valve pre amps with Cary valve power amps. V12r (s) in particular. Samra's Mac builds are pretty classic. I have a few. I usually use small planars and ribbons for monitors and DBA Servo bass systems these days.
Mac has tone control.
I have LS preamps Cary SLP-05 it's a keeper. I still like Macs though. Easy to find parts for the most part. I've never had a problem with over 75 pieces.. I kept 35 or so.. Vintage mainly.. HO trains too.. LOL
HT are nice MX120-170 all work just newer features.. Tough stuff for the most part.. I have a MC225 that looks brand new. It is actually. Yup, I collect stuff..
