Marantz 2275/2270 vintage receivers

The Marantz 22xx units are terrific. Second only to the
McIntosh MAC series receivers IMHO. I'd rank the Sherwoods
right behind the Marantz. I have 4 70s vintage SS receivers
I swap in/out of my bedroom system which is used almost
entirely for FM listening (main rig is almost entirely CD):

1976 Sherwood S-9910
1978 Pioneer SX-780
1979 McIntosh MAC-4100
1979 Yamaha CR-2040

I'd rank them against each other like this:

Amp section: McIntosh, Sherwood, Yamaha, Pioneer
Preamp Section: McIntosh, Yamaha, Sherwood, Pioneer
Tuner Section: Yamaha, Pioneer, McIntosh, Sherwood

The amp and tuner sections are uniformly excellent in the
units. The McIntosh/Sherwood amp sections are both awesome.
I expected it from the McIntosh. The Sherwood surprised me.
The tuner sections are all excellent. I ranked them pretty
much according to sensitivity as I live in a fringe
reception area and that's an important parameter for me.

It is in the preamp section that the McIntosh really puts
itself above the other units. This includes Marantz units
as well.

my son has my Marantz 2270 in his bedroom...still sounds as good as when I bought it in 1975

Ha! I still own my Marantz 2285 receiver purchased in 1978. I have never had a problem with its performance. I took it in to a local shop a few years ago for a dusting and cleaning and replaced all the blue lights just out of principle! The receiver has a by-pass feature that allows you to utilize the unit as a pre-amp, which is how it is working today! I use a B&K amp under the Marantz. The system fires a pair of JBL L65 speakers, which are also pushing past the 25 year mark! This was my first stereo system, and I am planing to pass it down to one of my children!
