Krell S-150M Mono Blocks

Thanks Cio52.

Steve Stone (TAS) loved them, but they are the "baby" krells and I wonder about power handling/capabilities

In a recent review in HIFICRITIC Martin Colloms found that the Krell S300i integrated had a very robust power output and considerably outdistanced some of their older large amps. These SHOULD be even better but in audio very little is certain.

One of the things I believe Krell always does is under-rate the watts and if you look at the high current capabilities (doubling of watts from 8 to 4 ohms) I don't think clipping or speaker matching will be a problem. I did look at the Music Direct website and these units are on back order. Not surprising with a great TAS approval.

I've switched my sights on the Krell S-150 Mono amp to the Krell S-275 Stereo amp here If anyone has any experience with this amp, I would appreciate some input.

I'm using a Class D amp currently (PS Audio GCC-250) and I plan on returning to A/B operation. Since my budget is $5,500 and I want as much power as I can afford, this Krell has peaked my interest. According to Steve Stone (TAS) the S-150 has extremely good highs and mid-range, as well as the renowned Krell bass control. The S-275 is based on identical circuitry…

Since I’m driving Krell speakers (Resolution IIs), I assume that Krell amps will be a good match. I’m certainly open to other SS amp choices, but I am interested in hearing about this particular amp. I would also invite opinions, or comparisons, about similarly priced SS amps (based on firsthand experience of course).

Merry Christmas to everyone.

Big holiday cheers…!

Hello Ben...
I have had a few Krell's over the years and keep going back to the FPBc/cx's. Although the more recent units are still all great amps with some of the better build quality, there just seems to be something missing. Given the used prices on the older FPBcx's it sure makes solid sense to me. You do lose some convenience with their massive size/weight but I find a warmth, smoothness, cohesion and naturalness that seeems to be lacking in the newer lines. I do use a KAV 3250 as well for Ht but FPB 600c for reference and love it still.
