Retro Hi End Trivia Question

I use to work at the factory! I was the sales manager for about a year - selling amps direct, advertising in the classified section of the LA Times. When I was selling amps - which was highly rated and cutted edge and inexpensive (and gorgeous) - other high dealers were selling anything but amps.

The gain cell circuit allowed the amp to clip with even-ordered harmonics, which was one of the reasons it had a "liquid" (tube) like sound. The bass was simply the best there was at the time. Still pretty good. Bought one on eBay for sentimental purposes and was suprised how good it sounded - so dynamic. Kinda like my Creek 4340SE. If I can find the time I might compare the two.

I have a Dunlap-Clarke Dreadnaught 1000, and it's still in daily use after 28 years! It's built like a tank, and I use it to drive the woofers on my Infinity RS1s.
The sound is comparable to other '70s solid state amps in this genre; very similar to the Marantz 500.
Whoever these guys were that engineered it built it to last -- it's one of my favorite vintage components.

The Quatre Gain Cell, ah...yes. I remember all the horror stories about how unstable they were, and the loud transformer hum. I was always curious about that amp until one day, at a local flea market, I spotted one. It had a silver face plate with one of the top corners bent over backward on the faceplate. I took it home for $10.00.

Totally fearless, I put it into my system (Dayton Wright SPS mk3 preamp, Rega Planar II turntable with Grace 707 tonearm and Grace F9L cartridge, CM Labs 912a power amp, JSE's "infinite slope" top of the line monster size speakers on casters.

The amp powered up instsntly and sounded much better than my CM Labs 912a (but that 912a was a drop dead gorgeous amp with that bronze faceplate and those huge backlit meters, and the oak side panels).

There was a midrange airiness with the Quatre that I hadn't heard from any transistor amps. The openness and transparency was absolutely intoxicating - along with the loud hum I noticed when the music stopped playing.

I opened the amp up and couldn't believe how little was inside. The transformer was huge - and loose. I cut some rubber pads and was able to wedge them under the transformer, then retighten the bolts which were under the amp on the bottom plate. It cut the hum to at least 3/4 of what it was. I also decided to glue cut up rubber computer pads on the inside of the amp at strategically loacated places along the sides and underneath the top cover plate. That reduced the hum to where it was now mostly inaudible, even with the ear placed close up to the amp.

I eventually sold it, but still remember to this day how incredibly transparent and open that amp sounded - along with bass that pounded your chest.

Too bad the company couldn't overcome the early reputation for them being unstable.

Anyone know with what serial number they overcame the instability problem?

Wow - having started this thread over 5 years ago, I have only just recently taken delivery of what appears to be a perfectly preserved Quatre Gain Cell from an Audiogon seller.

Cosmetically, it is exactly as I remember it - compact, but heavy, with a single LED along the the bottom of the faceplate with the power switch in the back.

I have not yet had time to listen to it properly, but switching it on to make sure it worked, it seemed to sound surprisingly good.

Now I will have to find a mint condition Apt Holman pre amp and a pair of Dahlquist DQ 10s to complete this vintage system.

When I worked at Quatre, we would often receive the better gear of the day for comparison.

I remember the Rappaport preamp was the best thing out there. (I strongly disagree with an early post). The Rappaport wasn't built that well, but if it didn't shock you, it worked and worked great. I remember someone brough in a gorgeous, state of the FET preamp from Infinity. It sounded so bad we wondered if it there was something wrong with it. We also tried the Apt Holman, which I don't remember being terribly impressed with. People would rave about the (Holman designed) preamp section of the Advent 300 receiver (I loved the look - very military), but didn't think the preamp was at all impressive.

The Denons were good MC cartridges, but I remember the hot setup was the Supex. But they kinda varied from unit to unit. When you got a good one - wow - was it ever good. The "bad" ones were not bad, but a good one was simply awesome.

I remember someone bringing in a pair (this was mid-to late 70's) of speakers from a very new company called Vandersteen. They were the 2s - which sounded very good indeed. One of our dealers brought in another new-ish speaker at the time - the Rogers BBC LS35a's. Very impressive little speaker. They still sound pretty good.

And we were awed by an old pait of AR3a's with the DG250 - man did that amp have good bass - it just transformed the AR's bottom end which tended to be on the tubby side.
