Anybody own or owned a McIntosh MC2250?

The issue with Theils is the impedance curve tends to dip around two ohms.
A levinson 23.5 can be had for 2K and the Mcintosh is around 1500 for a real nice example 8 or better.
Even though the Mcintosh has a little more power the 23.5 can deliver an endless amount of current and headroom. Just what your theils need served to them. Theils are a great speaker.
I would wait and save a little more money and try to grab a Rowland or Levinson
I think you will be very happy with that combo

I'm a Mcintosh guy but I never really though Mcintosh and Theil was the best marriage.

Bottom end with the QS amps is a bit loose and undefined. Top end is slightly rolled off, which would be a good thing for some Thiel owners, but not great for someone (me) who's been a drummer for forty years.

Levinson, Krell, and Rowland are going to be a LOT more $$ than the Mac.

I owned one for a short time. Very good amp with lots of power. Are the Quicksilvers running out of power?
I would think the Theils would be better suited with a high current amp like a levinson krell or rowland
