The SSP-60 and SSP-30 Mk II are described at audiorevolution.com, at at minimum. Classe seems to be pretty good at building the products and less good at ancilliary issues.
I own a CA200 power amp and an SSP-75 prepro. I am very happy with the sound of both of them. The engineering and build effort that went into them is pretty apparent, visually and audibly. They drive a MartinLogan Odyssey/Cinema/Descent/Scenario 5.1 configuration.
I auditioned the SSP-30 (Mk I) before I bought the SSP-75, and it is also quite a good piece, definitely better than the B&K Ref20 and Ref30 that I had previously. However, I caught the SSP75 right as the dealers were selling their demo stock in anticipation of the SSP-60 (which I believe is a few months late), so the '75 was about the same price as the '30 and therefore a nobrainer total nobrainer.
However, it's not an untarnished situation. The manuals for both products are TERRIBLE. T-E-R-R-I-B-L-E. There are seven buttons on my SSP-75 remote that are not even MENTIONED in the manual! There are numerous horrendous formatting errors, including a figure that is half overlapped on a paragrpah of text, rendering both virtually useless. At least the unit is a LOT simpler than a B&K Ref20, so the manual is a lot less important, but it's really inappropriate to pay $7000 for a prepro and not get a PERFECT manual in my opinion.
The documentation on the CA-200's remote trigger is both very sparse and just plain wrong for my unit, which appears to be a transition phase item. (I think it is one of the very last CA200's and it seems to have some of the features of the CA201 that replaced it.)
I also haven't had the best of luck dealing with Classe support, either. When I bought my CA200--used--it had a slight overshoot problem on power down, and THIS was handled smoothly and perfectly. I sent the unit back through my dealer, and when it came back it was perfect. With a new shipping carton and everything.
However, it's been a struggle figuring out how to integrate the units into my control system. As mentioned above, the documentation on the CA200's remote trigger is just wrong, at least in my manual. It took a couple of go-arounds with Classe for them to realize that the jumpers in my unit were simply not the same as their internal documentation, so there was NO WAY I was going to be able to set the jumpers according to their directions to reconfigure the unit.
The SSP75 *must* have some sort of discrete IR codes to have it power on and off, but I have been totally unable to communicate what I am seeking to the Classe service department. I want the IR code that does ONLY power on and the one that does power off, so I can program this into an RC5000 remote. They keep sending me the electrical signal codes that go between the IR receiver in the SSP and the internal microprocessor--which of course is not what I want.
Bottom line: great engineering, excellent build quality, superb resulting sound. Support for the basic engineering of the product is excellent. "Less important" stuff like manuals, control systems, etc are exasperating in a way that I could take for a $179 DVD player but which I find at least irritating when I have $10K invested in a prepro and a two-channel power amp.
