WOULD IT BE DUMB TO BUY A MARK LEVINSON NO 23.5

I just finished reading this thread...really sorry to hear you had to sell your new found treasure, jeffvegas.
Audiophiles are a fickle lot, so you'll get a crack at owning another one, or even a chance to buy yours back. Audiogon is like a pawnshop for audiophiles...
Hopefully 2021 will be better for everyone.

I am back at work and recovering financially. I am looking at a Mark Levinson No 335 to replace the 23.5. Can I expect the same good sound as the 23.5 with the 335? Will it sound better?

The 335 is a great amp, i feel the 3 series is better than the 4 series. Find a good power cord for it and you will be happy

The ML 33x series was plagued with faulty capacitor issues which are very expensive to service.  

This 335 has been completely refurbished with new capacitors. It is for sale at George Mayer AV. An Authorized service center for Mark Levinson.
