thanks for the responce...
I think they would be sort of the same in terms of power output. sure, they are not the same size or "class" rating, but its all about the ears, and I was just looking for someone to say "i've heard both, and they are very close, or very far apart..etc."
ah well.
i'll probably check out the Odysseys. more power is better for me. driving some VR4s.
The more I learn about audio, the more I think putting the best sounding system together is about synergy. Yes, synergy is becoming quite the cliche in audio, but I really think it has merit.
How are your VR4s characterized? Where do you think your weak spots are? How are the CI D100 / Stratos characterized? Which would bolster your weak spots better? Do you need an ultra efficient / low heat amplifier?
I recently demoed the Exodus UCD400 amplifier, which is probably really similar in sound to the CI D100.
I use Exodus 2641 towers. The midrange is very detailed. The highs are nice, but the Usher tweeter has been characterized by some as a touch soft at high frequencies. I also felt my old amplifier was lacking in bass grip.
With the Exodus UCD400 my midrange was almost too detailed for my taste. The UCD's are really detailed. I felt like the midrange at low volume levels was ever so slightly unnatural.
I recently had the opportunity to try a parasound hca3500 with my system (large class a/ab amp). Stereophile and others complain that the highs are a bit edgy with this amp. Given the somewhat soft highs my tweeter provide, this was actually a match for me. The midrange is a touch smoother and musical at low volume levels. This helps compensate for the highly detailed midrange driver in my speaker. The bass grip was really great with the UCDs, but the parasound matches it in that category too.
The UCD based Exodus was a great sounding amplifier in an impressive package at an impressive price. However, a good old fashioned class a/ab provided a better fit with my system and I am happier with the overall musical impression than I was with the Exodus UCD400. I bought the parasound.
I'd start listing characteristics of your speakers and current system. Then list the characteristics of the amplifiers you're considering. It'll at least give you a crude estimate of what to expect.
