1970's receivers and integrated amps...


Lots of the mid to late 1970's receivers (and integrated amps) look pretty cool. For example the high end Pioneers and Sansui's.

My question is how do they sound? Do any of them hold up to days standards? How is their power vs. what they are rated for?

Advise on particular models appreciated.

I have a early 70's vintage Pioneer SX-939 receiver that I bought recently on Craigs List. I have it hooked up to a big pair of VMPS RM2 ribbon hybrid speakers and it sounds quite impressive. The transients are fast and clean, the midrange is sweet and harmonically pleasing, bass is robust but not quite as controlled as with better separates.

But what really killed me about this receiver was how well it handled the fast transients and super dynamics of Rodrigo y Gabriella's blazing guitars from their CD 11:11. I was in awe, and you can check my other systems, it's not like I don't have semi-expensive gear to compare it to.

That said, sometimes these older units need a bit of service before they are ready to rock. Mine is stock but it had some dirty switches and the tuner section still needs realignment.

Happy Hunting. :)
It depends on your definition of hold up is. A good condition vintage receiver, mated to a compatible speaker, can sound anywhere from "vintage" (aka poor) to pretty damned fine. But I doubt that anyone would replace their Shindo gear with a used Pioneer receiver.

Having said that, I have restored vintage receivers and integrated amps that have been excellent systems in their own right. I bought a Luxman amp new in 1975, and regularly used in an office system it until I gave it to one of my daughters a few years ago. New caps are often (almost always) helpful if not necessary, and if you can't do it yourself the added expense might make the total cost unattractive.
Back in the late 70's, Harry Pearson, editor of The Absolute sound reviewed Pioneers top of the line 120wpc receiver. His review was only 5 words: "plainly a piece of shit". Receivers and amps from that period used huge amounts of negative feedback to make the numbers look good, but the sound was God-aweful.

Bob... I could care less about what Harry Pearson says or thinks. I do know I'm getting very good sound out of that Pioneer -- maybe not Shindo good, but still quite respectable. I'd put that system with the cheap Pioneer and VMPS up against your stuff any day.

I'm really put off by audio snobbery like this; especially when people have no first-hand experience with the gear they're giving opinions on. Sure I've heard some mediocre-to-poor receivers, but I've heard some good ones too. Also just FYI, my Pioneer is not the top-of-line 120-watt model and I bet Harry did not even give that one an honest chance with an open mind.

Tried a Marantz integrated (forget the model #) to hear what it sounded like and it was warm and and euphonic and rolled off on top. When I hooked it up it bottomed out my drivers which startled me. All that juice still in the caps. It brought back memories and I appreciate the nostalgia but it was mid-fi, at best. At least with that model in the context of my system and my tastes. It would be good in a garage system and that is not a put down as I enjoy the looks and feel of vintage gear. No doubt there are better makes and models but I think one would have to look far and wide and maybe recap some to get a good sounding unit.
