Thank you for your all postings!
I did not have any experience with Krell powers, but I auditioned 300i integrated amp with Audience 60.
Please don't mad at me, all Krell 300i owners. In my experience, I don't know why 300i is so expensive ($2500).
Yes, the base was slamming, but that was it. May be I don't like too much kicking base, but I love tight and dynamic base, but Krell's sound was little bit off.
I have heard that Krell's KAV250a and 300i shares the same power, so I expect similar result with KAV250a.
I don't know.............Maybe, just Krell's pre amp in 300i is just not my type. I better try with KAV250a.
The reason why I am considering KSA 50 as a candidate is that so many people say the Krell is the best match with Dynaudio, and it is around my budget.
Anyway, I live in LA, CA, and no dealer has Aleph 3 any more.
By the way, I am pretty impressed with Mr. Nelson Pass. Yesterday, I emailed the similar question to him ,and I got an immediate reply from him. I think he knows what he is doing, and he must be a sincere person.
