SimAudio or Classe for Power Amplifier

As I continue to upgrade my system I am looking at the amplifier as the next component on the hit list.

My current system:
- Marantz SA-14 SACD player (modified by Tube Research Labs)
- Conrad-Johnson 17LS Tube Preamplifier (Amperex Holland 60s tubes)
- Rotel RMB-1095 5X200W power amplifier
- Wilson Benesch Discovery loudspeakers

I am looking for a solid-state power amplifier with 200WPC minimum to drive the WB loudspeakers. I originally thought of getting a set of Parasound JC-1 monoblocks but realize that the heat dissipation would be an issue in my modest sized room. I will stick with a tube preamplifier however the brand/model may evolve over time.

Living in Canada, I thought that SimAudio and Classe would be two companies worth investigating. Both of these Quebec, Canada based companies have a good reputation for building high quality power amplifiers. Also both appear to be stable financially.

The current models I am looking at are:
- SimAudio WS, 190WPC
- Classe CA2200, 200WPC

If I win the lottery, I might consider getting the monoblock versions, ;-}
- SimAudio W10, 750WPC
- Classe CAM400, 400WPC

I am interested in the feedback of those who have compared the amplifiers of these two companies. Also feedback about these companies in general. I understand that Classe is now owned by the holding company that owns B&W and has a stake in Rotel. Not sure if SimAudio is still an independent company.

I purchased a Simaudio Moon W-5LE a few months ago and it continues to impress me. The 'LE' is a limited edition run of only 250 with higher quality parts. I suspect the non-LE W-5s are good as well, but I haven't had the chance to compare. Since this line of amps is has recently been replaced by their newer line, you may find a dealer that is willing to deal. Don't know about Canada, but in the U.S. you do not find this amps at much of a discount. The best opportunity to 'catch a deal' appears to be when the product line is switching out.

I also have a tube preamp, Aesthetix Calypso, and I found the pairing with the Simaudio with it was a great match. That being said, using the balanced connection rather than the unbalanced, made a sizeable difference. I don't know if your CJ has a pair of xlr outs or not, but in my case it made a noticable difference toward the good.

The W-5LE is a dual mono design with fully balanced differential to the output stage. It is rated at 200 wps at 8 Ohm and 400 wps at 4. My loudspeakers are JM Labs Mini Utopias (91.5 dB) and the W-5LE hardy works up a sweat driving these bad boys. Needless to say, clipping is NOT an issue.

Lastly, I purchased a demo W-5LE directly from an authorized dealer so I got a full 10 year warranty on the amp. It's built like a tank, so I'll probably never need to use it, but I think that says a lot about the manufacturers confidence in there product.

Good luck!
