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

I had a Kav-500 3-channel driving my center and rears for a couple of years...a nice little amp. I would guess that the two amps have the same sonic signature...the Kav-250 would have a good deal more, "power to spare"....you may want to consider this factor in?

The 3-channel Kav-500 has a 1 kva transformer, and is rated as 120 watts at 8 ohms load....240 watts at 4 ohm load. It's sound is highly detailed, but not, "over the top" bright (still, maybe not a good match with some tweeters)...pretty good bass too, for only a baby Krell.

This will be for the fronts and center.

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).

I concur, with Sogood51, without a doubt for the front 3 speakers.

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.
