Eavr11: I tried several times yesterday to reply to your message to me earlier this week but my cable ISP kept responding back that your email address provider was not accepting the message. So earlier today, I sent my reply to you through the A'gon system. My reply was not in response to the LS15 that you are using. If you would like more detail with this model, send me another note.
42659, This is not the first time I have heard it said that the CAT Ultimate is not a particulary good match with the CAT amps - althought it seems strange that they would not work well together. Can you clarify what it was about the combination that you found disappointing? What did the Hovland and Jadis "bring to the table" when used with the CAT amp? Thanks.
For the last two months I have done some serious comparisons of the Aesthetix Io/Callisto vs. the CAT Ultimate II driving CAT JL-3 Signature amps. There are significant differences here with each "preamp" having strengths over the other. Both preamps greatly benefit from the replacement of their stock Sovtek tubes. A more fair comparison would be with the upcoming CAT Legend preamp which I hope to try out sometime this year.
I can see how there would be two camps on which was the "better" preamp: one camp saying the other side is too warm and euphonic; the second camp saying the other side is too analytical.
I do not view this as an issue of the two CAT products "not working well" but rather a matter of personal taste. I think we get too focused to seek a consensus on what is "best" rather than to assemble a system for ourself that once we start the music, we play for hours and hours and hours.
