Calypso Amplifier Matching - Krell?


I am seeking a new preamp and the Calypso is one on my list. I have read that there are potential impdenence matching issues with some power amps. I have read the measurements in Stereophile regarding some of this, but am a bit concerned that I may not be technically savvy enough to make the right determination.

To the point - I have a Krell FPB 200 that I have really enjoyed and want anybody's knowledge feedback as to the synergy between this preamp and this amp (FYI - speakers are Watt/Puppy and RA-Opus 21-GNSC CDP).

Also, impedence matching issues between the two?

Any ADDITIONAL comments on the pre over the above would be welcomed as well.

Thanks much in advance.

Guess nobody has an expierence between the two? I went ahead and ordered a Calypso and will post comments in due course as to the sound and any issues with the potential impedence matching.
I spoke with Musical Surroundings, the sales organization for Aesthetix and they confirmed with me that the Calypso has coupling capacitors at the output which protect against DC from going to your solid state amps. If you have a Krell, this means you do not need to activate the coupling capacitors within your krell amp to run the Aesthetix Calypso (and from what I understand, their other preamps as well).

Also, I spoke with Steve at MS (above) who runs his Aesthetix with a Krell FPB amp and he has reported excellent results and a great deal of satisfaction.
Hi,

Sorry I only just came across your thread.

I normally use a Krell KRC HR with my FPB300c power amp in my system but a friend who has a Calypso lent this to me while he is on vacation and I used it with no problems at all with my FPB. The sound was excellent, warmer than the KRC with a richer mid bass balance though it can be argued that the Calypso does not have that last nth degree of crystalline clarity & resolution. On the other hand, the Calypso allows more midrange detail to come through than the KRC, especially on brighter recordings. The sound stage is less wide than with the KRC though this may be due to the fact that my friend's Calypso is using standard tubes.

Overall, I have to say I am tempted to get one though I am at present undecided yet.

And it is true the Capypso is capacitor coupled which will prevent any DC offset at its output.

Hope this helps.
Solntgreen, Thanks for your comments. I am a bit surprised that the sound stage was not as wide with the Calypso. I have read very positive comments on the sound staging ability of the Calypso.

I figured I would give up some "crystaline clafity" due to the tubes. I look forward to getting it this week and hooking it up next weekend.
