I am using two Krell Evo 600E monblocks for R/L channels with music and home theater. The Evo 600e is a stunning amp. I use two Krell S275 amps for home theater only. One S275 amp is used to bi-amp my center channel speaker (my processor has 2 center channel outs) and the second S275 for the two surround channels. The S275 replaced my Krell 3X250 amp. I use cast for the 600E's, balanced connections for the S275's. The S275 is a much better amp than the 3X250 Krell. Since I don't use them for music, I don't have a feeling for their ability to create a 3 dimensional sound stage, dynamics, tight bass, transients, speed as I do with the Evo600e's. I have had no problems with the S275's, I like them very much. They are dead quiet and they provide more power than I need. They probably perform much better than the small Krell 150 monoblocks, which recieved very positive reviews. They are compact in all dimensions except for depth and weigh 50lbs each. The S275 is very nice, but it is not in the same class as the evo amps. If you plan to use the amps for music only and you don't want to pay the cash for a new Krell EVO e series amp, I advise looking for two Krell 450 mcx or 650 mcx monoblocks. I owned the 450 mcx's and loved them. They are great, extended frequency range amps (fast, detailed, 3 dimensional sound stage, great instrument seperation, nice highs, great tight detailed bass). They will not fit into a rack as well as the S275. You should be able to pick them up for a great price if you can find them. But keep in mind, you need a very good preamp and/or processor with the high end amps to get them to sound their best. I think the pre-amp/processor is every bit as important as the amp, if not more important. Hope this helps. Good luck.
Krell FPB 600 or 400cx?
I own Revel Ultima Salon 2s and am looking to upgrade my amp for better performance in the low end. Right now I'm just not getting any real punch or slam in the bass dept, and I know the Salons are capable of much more. I have the opportunity to go with a fpb 600 or the 400cx for around the same price. Any thoughts? Is the extra 200 watts of power on the 600 worth losing any sonic benefits of cx? Or is the cx so superior sonically that there's no comparison?
Thanks.
