Amp choices are of course limitless. I remember my buddy Any Homeyer in NM telling me the parts inside McIntosh are all coming from China.
Some people love Rack Handles on Amps-etc. Like you're in some freaking Red October Nuclear Sub
And everybody and their brother has done rack handles to death.
Carver, Mac, Accuphase, Krell, Levinson, Bryston, it would take 3 months to read through all there were in our Audio Hstory.
Ivan over at Aficionado in fact back in time was putting together some retro-fit kits for a good number of other McIntosh Models (Amps-Pre-Amps-etc) that never came stock with Rack Handles. He commissioned some NASA-Grade shop to clone the Handles. I seen quite a few pics, they were drop dead gorgeous! The end results did look very nice IMO.
I believe the MC-352 was one that could have this Rack Handle Upgrade.
Speaking of Subs, (no not the kind you eat), wasn't a particular Mac Amp in use in US Subs? MC-2600?
1.21 Gigawatts LOL
Here's another very cool Mac Amp, that gets little press and is nobody's "chump", the 352's bigger brother, the MC-402. Looks like a sweet easy fit on most everyday Racks that can handle its weight
You'll likely read a lot good things. (We Cool!) LOL
