Top vintage receivers vs. modern high-end equipment


I am considering pairing an old amplification system to my JBL Paragon -- the idea of getting an all vintage system is very attractive to me. Among other things, I am looking into classics such as the Pioneer 1980 receiver or the Marantz 2600. Does anyone have direct experience in comparing this kind of equipment (very high-end but 40 years ago) to current high-end equipment, imagine an integrated Pass Lab amplifier? How do they stack up? Thank you.

I agree with the others who have suggested that to do justice to this classic speaker you consider classic tube electronics, which you appear to be receptive to based on your second post. The Paragon was of course designed prior to the advent of solid state amplification, although I believe a "series ii" version was introduced during the 1980s.

There are lots of good choices at various price points, of course. And the condition of the specific example you choose may very well be a more important factor in terms of sonics than the make and model, although a satisfactory restoration is usually possible.

All of the tube pieces that were suggested above by the others (and by you) are excellent. H. H. Scott and Pilot, among others, also made fine pieces in those days, which can be found today for relatively modest prices.

As you are no doubt aware McIntosh and especially Marantz tube equipment unfortunately tends to be very expensive. But having owned several of the classic Marantz pieces during the 1990s (Models 1, 2, 7, 9, and two different 10Bs; stereo pairs in the case of mono units), I can attest that they command high prices for good reason. My sonic favorite among all those models, btw, were the stereo pair of Model 2 monoblock amplifiers I had. I only sold them because in triode mode, which I found to be sonically preferable to ultralinear, the ~20 watts they produced were not quite enough for the speakers I had at the time, when playing recordings having particularly wide dynamic range. In the case of your Paragon I doubt that would be a problem, but the problem would be that a pair in nice condition would likely cost well north of $10K these days.

I’ve never heard a Marantz 8B, which of course is well regarded while also being more easily findable and much less expensive than a pair of 2s (or the still more expensive 9s). However unlike the 2 and the 9 I don’t think the 8B provides a triode/ultralinear switch, and I believe internal wiring changes would be necessary for it to operate in triode mode.

Good luck, however you decide to proceed. Regards,

I think the op wants to have some fun with his set up.  The Onkyo 8500 was mentioned above. I will second that. The onkyo tx4500 and tx8500 get little love, and are way under the radar.  You should be able to get a nice example for around $500.  No marantz or pioneer tax on good vintage sound.  If you end up not liking it, simply resell it.  
Skip vintage ss and go tube. An old marantz, McIntosh, fisher or sansui tube setup with those paragons would be fantastic. Good luck 
My 2 cents. McIntosh MR78 is an excellent tuner that also has that look. If you get lucky, maybe it has had the Modafferi modification already done. Pair it with a classic integrated unit. Synergy doesn't seem to be all that important since it is just a tuner.  Better yet, add the McIntosh Mi3 to hone in the tuning and add awesome visuals at the same time.
I bought a Sansui AU-7700 and love it so much I bought another Sansui of the more advanced alpha series... The sound is more refine yes, but I like the Au-7700 so much, that I listen to it mostly with speakers and headphone... There is better ? Yes, but at which price? And better for what? Where is the contemporary product that have so useful tone controls of the highest quality, a separated pre-amp function of great quality, a useful loudness button, a phono section of the highest quality adjustable , etc etc...? The answer is no contemporary amplifier had these many features...

The Sansui is so good that I dont listen to any limitation when upgrading the source, on the contrary with any upgrade of source, with any tweak to the electro-magnetic fields of the gear and room, the Sansui seems to sound better, totally detailed and organic, holographic and tube-like...

The real question is not: should i buy vintage or contemporary ?... The real question is "with a low investment", which contemporary low cost amplifier can beat a Queen of yesterday’s audiophile kingdom like a TOTL Sansui ? The answer is none ...

I can crush my Sansui if I buy for example a dreamed Berning ZOTL amplifier around 5000 bucks, but the Sansui cost me 100 bucks+150 bucks to clean the old catalytics etc... The other question is the Berning amplifier will be better but the margin of improvement will equate with 4,500 bucks more than the Sansui price... Is the Sansui so bad that I want to upgrade it? The answer is no, except if I bought a winning lottery ticket...
