Just found and remembered that I have a couple of other components I had forgotten about. For an FM receiver I have an ADCOM GFT-555 II and I found my SAE MARK 31B but what I really liked finding again was a little preamp that in a pinch with the SAE 31B and either the Advents or the Infinity's was just a nice small room sound and that's this Ace Audio great little preamp.

A couple of guys were asking about the Marantz 2600...
This was the most powerful stereo receiver every built, it would put out 400Wx2, incredible phono preamp circuit, 5-gang FM quartz-lock tuning, scope that would indicate FM signal strength/center channel/multipath simultaneously.
Originally sold for $1595, but Marantz underestimated it sales and was always sold out. Also below is a photo of the heat sink tunnel split apart. The amplifier section was a patented, servo control tunnel design taken from their pro-audio amplifier 510M which powered many, many touring big-name music groups including the Eagles, Rhonstadt, Crosby/Stills/Nash, Steve Miller, Bonnie Raitt. I was fortunate to snag a 2600 and can only comment its kicks ass!!! Also today they are scarce as in good condition can sell for as much as $10,000..

Just my $0.02...

Cambridge Audio AXR 100 receiver for the mains & Bryston 4B power amp for the subs.

Sources are an NAD 512 compact disc player & Rega Planar 2 turntable. Plus the Panasonic Blue ray, cable box & Apple TV. I don’t do surround sound because I find all of those receivers sound like crap playing music, which is most important to me…

Speakers are Paradigm Monitor 8000 towers (each with 3 x 8” bass drivers, 6” mid plus tweeter.)

Subs are also Paradigm dual voice coil 10” units from the ‘90s which warm up the bottom end nicely.

In the den/finished basement:

Marantz 2240B receiver
Marantz 5220 cassette deck
Marantz 6200 turntable
Bose 501 series IV speakers

In my shop:

Marantz 2220B receiver
Marantz 5020 cassette deck
Bose 301 series 2 speakers

Have about a 10 year old Pioneer surround system with Boston bookshelf speakers & sub for the main living area

Thanks for the info! I really enjoy the oldie stations on it...Can't miss Kasey Kasem's American top 40 from the 70s every Saturday!

Some of the vintage Stereo equipment that I have owned since the mid 70's
Just collecting dust today...

SAE Mark 30 Pre Amp
SAE Mark 31B Power Amp
Onkyo T-4085 AM/FM Tuner

That SAE Mark 31B and the SAE Mark 30 are GREAT components

My main system right now is a Yamaha RX596 receiver, Kenwood turntable, & 12" woofer 3-way KLH loudspeakers. I rebuilt the speakers about 10 years ago with Dayton woofers, & Goldwood midranges, & can't remember which tweeters, but I went from cone tweeters to horn tweeters - they sound better now than when they were all orig. components.

I'm glad this topic was posted. I've been playing my old gear for months, every late afternoon playing chuck-it with the dogs.
I've been using an old 5 disc cd changer playing remastered cds and mixing in some vinyl every now and then.
Several songs I'm really impressed with the sound engineering. One really stands out to me; Cream - Sunshine of my Love. The separation of the hard hitting drums and the guitar with the voice imaging in the center. Very basic and nearly unbelievable without being too much (like Winters Frankenstein).
For the old rock fans

I'm anxiously awaiting the arrival of a completely refurbished Sansui G-7500 that I purchased over the weekend. It is replacing the Sansui G-7000 that I bought in 1979. The power supply on the G-7000 shorted out after about 20 years. At the time, it was not economically feasible for me to have it repaired. So, I reluctantly took it to an electronic recycling facility. I had been looking for a replacement for quite a while and finally located the G-7500.
The G-7000 was 85 wpc and really sounded great through my Norman Laboratories #10 speakers (which I still have).
The G-7500 is 90 wpc so it should get the twin 10" woofers in each of the speakers really pumping.
I inherited my father in law's Pioneer turntable. I'm not sure of the model but it's a really nice setup. It's probably over 30 years old and still in pristine condition. My father in law was very proud of it. He just never used it much.
It should sound good on the 500+ albums my wife and I have.
