I have been a user of Krell's power amplifiers for many years.

It started with Krell KSA 250. It is a very powerful amplifier with great bass slam and authority; slightly thin in the mids. Then I changed to KSA 300S, a more refined performer, but equally powerful.

Perhaps it was the heat and the very high current, the KSA 250 had its on/off relay burnt and the KSA 300S had the same problems. My first Krell 300S had its on/off switch burnt one time and the huge transformer burnt later. The replacements had kept me waiting for a few months. Then I changed to another Krell 300S. It worked fine until one day it burnt all the left side. Tragic! Repair needed another 3 months.

Yet, I kept returning to Krell for one reason - no other amplifiers at the price point can match the Krells. The amp's sound will be greatly affected by what it sits on. The famous Chinese audiophile, Albert Yeung's invention of tips made with crystal and expensive wood has the magic of bringing out the real beauty in the Krells.

Recently, I changed my KSA 300s to Krell FPB 250Ms. It was a significant step upward. The sound was amazingly transparent and detailed. Sound stage was further stretched in all dimensions. The highs are conveyed with a sense of elegance and unbelievable refinement. Yet, it still loses points to KSA 300S on bass weight and authority. Perhaps, a change to more expensive power cords can improve in this respect. I am experimenting with a few. My former positive experence with an Aural Symphonics Cube GII power cord on the KSA 300S has convinced me a possibility of improvement. I am looking for another one for a change of them to 20A sockets, as the Krell 250Ms need 2 power cords.

A perfect amplifier. Just want a bit more bass weight and authority that the Krell 300S had offered me for the last few years.

These 'little' monoblocks from Krell are great. I compared them to the FPB600 stereo amp and was impressed that the little guys had all the same great qualities: resolution, pace, no-harshness, etc.

Have matched them with B&W 801's, which was excellent, and I am currently driving Wilson Watt/Puppies and they are a great match.

Make sure that you can handle the blue lights before you buy them, some of my friends find the light distracting in my rather dark listening room. They also require ventilation - they idle warm and run hot.

They sound better with the balanced inputs.

Strength:

Soundstage; musscle; transparency;

none i can see

This prodcut rightly achieves Stereophile class A staus - well deserved. Truly a Ferrari of the hi-fi world. Try plugging it into a PS Audio power plant and it's as if the Ferrari has acquired a further turbo.....

Strength:

power, transparency, abosulte control; build quality

Weakness:

none to speak of

Been using the 250m monoblocs for over a year and they never cease to amaze me with thir iron like grip on my Sonus Faber speakers. They are infatuiguable. I agree with Dave from Dagenham, UK that you can improve performance even more with good quality 20amp power cords and by using balanced inputs. Kimber Select balance cable discerably improved the soudstage and isolated instruments. Transparent across the range and never harsh. Typical Krell bulletproof build quality.

A real bargain if (like me) you can pick up a second hand pair.

Strength:

power; soundstage; legendary Krell build quality

Weakness:

none

This review is for the 250m and not the 250mc. The main difference (other than cosmetics) is Krell's new CAST technology which (unless you're using other CAST components) means that any used pair of 250m will be a true bargain compared with the 250mc.

At this price range, however, any review of amps is more about personal musical preferences and component synergy than simply better/worse.

I bought these after reviewing a number of high end models. I found them brighter, punchier and more detailed than the Levinson 332. Within the Krell family, they had better soundstage and warmer mid-range than the FBP 350; FBP 350 has more grunt and bass slam.

I found that balanced (xlr) cable produced best results. Also, these monoblocs deserve better 20 amp power cords than the ones supplied. In my system, even some inexpensive proprietary power cords truly made a huge difference.

As someone who has been seaching for hi-fi nirvana for about 5 years, I believe (after some months with these) that my amp lust is over.
