I have fond memories of my Pioneer SA-9100. Currently running a silver Parasound Hint, which I consider to be a reliable modern-day take on classic integrateds.

Kenwood KA- 7002. It was my second ever piece of HiFi gear. Replaced my Kenwood KR-4140 in my senior year of college (1972). Had it measured at a McIntosh clinic at the audio store I went to work for after graduation. FR was flat and both distortion and noise were low. Lovely piece of kit.
I had the power amp version, the KM-8002 -- it had a lot of features usually found in integrated models like Ken's KA-7002, e.g. a line-level input selector, terminals and switching for three pairs of speakers, and a headphone jack. Those amps were among the first to have DC-coupled output stages, which was a major advance in amp design at the time. Like Ken, I took mine to a McIntosh clinic and it acquitted itself admirably. I think the solid performance of those 1970s Japanese amps was one of the (several) reasons McIntosh stopped testing non-McIntosh amps and eventually stopped holding those clinics -- it was sort of embarrassing that such relatively low-priced imports was performing pretty competitively with their "high-end" counterparts.

The Yamaha AS-3000 is so beautiful.
You have good taste in music.My only system: 1976-1978 trifecta of Yamaha CA-1010, NS-670, YP-511
With 1990 thrown in: NS-1 Classics, YST-SW500
May not have s/n, SINAD, flat frequency chart topping specs but it can time travel!
I always smile putting on an album my parents bought in the 70’s because it sounds as if they never stopped playing their music 45+ years later….one very long listening session.
Thank you for your kind attention! I also shared this post #38 on this thread...The Yamaha AS-3000 is so beautiful.
Yes you should!, or have them Cleaned /Restored and just USE them that's what i would do, beautiful looking kitI still have this classic Kenwood Supreme 600 combo gathering dust. Drove a pair of QUAD ESL-63s, also gathering dust. Nothing quite like the feel of solid metal milled knobs and switches, no plastic here. I should put them up for sale, I suppose.

NiceMeters.
Proven to improve how an amplifier sounds.
If Ramsey said "you eat with your eyes first,"View attachment 386230 perhaps you listen with your eyes first also, lol
Damn £30 for one pristine Technics SU7300 it's just to congratulate. It is also stylish.I bought a pristine Technics SU7300 last week. Mainly because it was £30 but also because I remember having one before and thinking it was better than I'd expected.
So, taking things a bit more seriously this time, I've compared it to everything I currently have: Rega brio, Roksan K2, Cyrus 8xp and an Aiyima A07 max, amongst others.
This is an astonishingly good amplifier! It's clarity, soundstage, looks and sheer listening pleasure beat each of the above imo.
I'm a bit shocked as I've always thought of vintage mid end stuff as a bit of a novelty.
This is completely subjective and only based on listening tests but I'd say although both the Cyrus and Roksan are better at certain things (bass definition mainly) it's honestly not by an awful lot.
The aiyima in particular sounds dry and weedy now.
Sorry for the long post-just not sure where else I might get interesting feedback.

If it is possible to hear any difference between your amplifiers, I am guessing that it could perhaps be that the Technics SU7300 only has a damping factor of 20 (4 Ohm) that affects that. Maybe, but that is just a guess on my part. It also depends on which speakers you have.
Aiyima A07 max is load dependent which I guess Technics SU7300 is not. That, depending on the speaker, its load, can make them sound different. Note may, need not be so.
Then you can weigh preconceived notions and imagination factors into the whole thing. But in any case, congratulations again on a nice find.

Sounds like you have a nice experience.Thanks!
I tried various speakers, all decent but my Harbeths made it very clear that this amp competes well with modern kit. The clarity was superb. High volume is possibly it's weakness but we are talking ridiculous levels through my old RS6's that I never get close to.
Yes, if the subwoofer has some means of level attenuation, and/or if one adds an in-line attenuator. The problem with TAPE OUT is it's at a fixed output level, independent of the volume control setting or any other preamp controls (ahem, e.g., tone controls). That said, if one controls level upstream of the little Technics integrated amp (e.g., the source component has some sort of adjustable attenuation, perhaps via a remote control) -- well, then, Bob's your uncle!Sounds like you have a nice experience.
Some general thoughts. I wonder if you can use the tape out , rec out:
View attachment 397787
..on a Technics SU7300 to send that signal to an active subwoofer? In that case, you must have a pre amp or DAC with volume control that is fed into the Technics SU7300 so that you can change the volume of the Technics SU7300 and the subwoofer at the same time.
That if Technics SU7300s tape out works for such a setup, that is.
That if you want subwoofers in your solution, but that's another question.
Given the Technics SU7300 damping factor, I would have probably let it power up 8 Ohm speakers. Then those with a sensitivity of at least 88 dB.
But with that said, 20 in damping factor at 4 Ohm if it affects the sound, FR? I don't know.
As the saying goes, if it ain't broke, don't fix it, I usually sign. Having said that, close to 50 years old, then maybe the amplifier would benefit from some electronic components being replaced? What speaks against it is as you said: pristine it may not have been used and worn so much over the years so then it is not needed.
Edit:
Speaking of damping factor, from another thread. Page 7, #140 and page 8, #141:

Are tubes more musical?
Whilst the above is true for the damping factors shown, except for some zero-feedback SET amplifiers, which in my view are not amplifiers, but effects boxes, most half-decent valve amplifiers of the 1950s and 60s had damping factors of 16+, so the frequency response variations were acceptably...audiosciencereview.com

I did indeed. Thanks/sorry!I think you may have overlooked part of the comment you quoted?

A setup with Tape output to subwoofer is exactly what I did with my vintage HK330C.Trim the volume on the HK330C and on the amplifier in the subwoofer to match, then adjust the master volume via a Topping E30 DAC when listening to the music. It worked fine.I did indeed. Thanks/sorry!
