Krell KAV-250a/3 or KAV-500?


I have a Krell HTS 5.1 and Thiel CS 1.5s, and I'm trying to decide which three channel amp to get. I'm strongly biased toward matching the preamp and amp, so I'd like to get something else from Krell. Does anyone have any opinions on the KAV-500 (in 3 channel configuration) versus the KAV-250a/3?

I would go with more power then. The Kav-250 probably has twice the transformer size of the Kav-500...the center and mains will hit it hard, as that is where most of the sound is in movies.

I used a Ksa-250 with my Kav-500...Apogee Duettas for mains, and Apogee Centaur Minor for center, and rear duty....this was a few years back....(early multichannel SACD days).

Is power the only factor for that? The Thiels are 4 ohm speakers, so the KAV-500 would be giving them 240 wpc. The recommended power for the speakers is 50-150 watts. It seems like even the KAV-500 would be plenty, and the 500 wpc at 4 ohms that the KAV-250a would provide would be excess.
I did hook the Kav-500 to my 4ohm Apogee Duetta Signatures while I owned it. As I stated, the Kav-500 usually drove my center, and rears...a Krell Ksa-250 drove the Duetta Signature front L+R speakers at that time.

The little Kav-500, had no problem driving the "fairly large" Apogee panels to quite hi spl's in my room. I'm not up to speed on the Thiel CS 1.5s though?

I found an old Stereophile review of your speakers, the Kav-500 will drive them with ease.

BTW...use balanced connections with Krell amps.
