Wow, I have the MX120, C2500, and a bunch of the older tube gear.
I'm a Wilson fan. Just not an owner. I can't imagine a better "STEREO"
Pre amp. The 120s are really TWO separate units, stereo, and a surround system. Kinda unique.
I think you can still PLAY THROUGH with a tricked out surround processor, and keep that wonderful, Mac SS Preamp STEREO sound. The120s have traditional tone control Mac WAS known for. A 121,or 122 is NOT a 120. Not at all. In the Stereo department. You have to listen, BUT NOT TO HARD.. lol I sold a 151 for just that reason, TONE CONTROL. I might have been happy with a 150 NOT UPGRADED.
I like tubes, so I play my C11s,20s,MX110s and 2500, THROUGH the 120, sometimes. Works quite well. I bet those Wilsons WOULD sound
wonderful on the old restored Mac Gear. C20/225,240,275,30,and 60s
are ALL quit wonderful to listen to, in their own right. The 60s are close to 100 watts when built right, and can be strapped, BRIDGED par/ser either or. Mac gear is some serious gear if you want it to be..Your call
I'm also a BIG fan of the new class Ds I just love the tube, class d combo on some of my speakers. BLACK background NO NOISE NONE.
I built a system up from VMPS speakers, DIY, and GR Research OB Servo bass systems. Planars and servo controlled bass just seems to be the best for speed and control. Building speaker is not all its built up to be. IT'S HARD WORK, To do it right.. I'm old,, lol
Building speakers or having GR do it for you, is that an option???
You a planar guy, or a Wilson purest???
Have fun in any case
