Looking for ideas - new mono blocks for stereo music

Krell Solo 375 Monoblocks are by far exactly what you are looking for. They have the auto-bias Class A and just have a softer way of bringing the treble. The treble is not rolled off, just not what some of these so called state of the art amps do to your ears. Krell does Class A right. No matter how many amps I put into my system, nothing sounds better with my Martin Logans. I sold all my other amps and now have 3 Krells. Currently I'm using one with the auto-bias Class A and it really works. I am constantly reminded how much a proper Class A design can produce vocals and instruments with weight and clarity that is non fatiguing. If you can't afford new, just look for used. I don't like the Evolution models, but ones before that have the auto bias technology. Bryston is great for reliability, but can't really give you what Krell does with musicality. I'm sure some like Pass Labs, and power to ya. But back to back, the Krells or D'ags with give a faster decay from instruments, and thus more natural. Let the mud slinging begin.

Just saw on Ebay and also direct from HiFiHeaven in Green Bay, Wisc. a pair of Krell Solo 375 monos for $4,400.00 each. Mint condition. Authorized Dealer. Just an FYI.

I agree with many here...Having mono amplifiers does not make for a significant difference between a good stereo amplifier. The best money spent is on a good sounding system. If you think having 2 boxes is BETTER, then you are not giving a whole world of amp design a chance. Do I want to have 2 Krell mono amps over my 3 stereo amps? Not a chance. Every bit of technology is wrapped up in the proper design of the amplifier itself. I'm sure that many that are "in the know", have an understanding of what it takes to make for an amplifier that does the same thing as 2 mono amplifiers. Amplifier 101 is that there is a way to use power supplies, and transistors in a way that makes them not wanting for help. High Current amplifiers are designed to work in many different ways. But the common denominator is to have an amplifier feed enough current and have a design that brings the sound to it's finest output. If you think that mono amplifiers are superior to stereo, well that is just your opinion. To this day.... a proper Class A design will be the best sound. I am not a guru, but a person that liked a few Class D amps. And then hour after hour, I jumped ship with Class D. Still have not found a replacement for a good Class A sound. The auto bias feature with Class A will save the cooling and electric bill. But if you have to warm up your amp for longer than an hour or two.... maybe you should find another brand. Some of the best amps ever are stereo. And they are also Class A. My take on the mono crap. What if both monos don't match? OMG

@auxinput. You are right about that some offer the fully balanced differential design.
I own 3 Vintage Krell amplifiers. The amount of power supply, capacitors, output transistors and protection is pure overkill. The ML Montis speakers drop down to below 1 ohm at times. My KSA-250, KSA-200S, KST-100 have some kind of sound that fills in, instead of applying more db levels. Most volume controls turn up the sound level and thin out what's playing. Not what I own. It's going to get fuller the sound before it gets louder. This is my best way to explain it.

Let's get this straight..... I am fully open to what you have to say about what you are up to, and that there may be a better world than Class A. 
I spent a lot of time (40 years) perfecting Car Stereo to audiophile standards. Since 1970 for my Home Stereo beginnings, and in the back room with many audio circuit designers.
There is not a day that I cannot learn from others. I welcome anything that brings more to the table.

I listen to all types of music on TIDAL quite a bit now. Funny how I used to listen to my CDs or FLAC files a lot more. But now, I like to explore new worlds in what's out there. Latest is from Jamaica artists combining club music with the Island Vibe. Or female artists that are new and exciting. That's what we all are here for.

Been about 8 months since I have finally said my system is finished........ done

@AUXINPUT,
Your last post about fuse change was extremely well done. I have always wanted to know about this ability of fuse change in a controlled environment with enough time with good equipment to tell the differences of what the fuse is doing.
Bryston amplifiers are the reliable workhorses that usually sound very solid state, and could use some kind of a soft source or tube preamp to give that body to the music that most spend the big dollars for. I had no idea that the fuse change could get a good result that would be so worth it to Bryston owners.
The JC1 monoblocks have been something I would love to hear on my system one day. 
Took a long time for me to get the system synergy that I have heard before. The wiring of the interconnects and speaker wire changes things dramatically. It can drive you crazy, changing and listening with break-in time (if you buy new).


When I was younger, I had an Audio business. It was just "high end audio design" and installation. During installations, I had up to a dozen interconnects, and 4 pairs of speaker wire to tune the system. Had so much fun with other people's money, and going into these high end homes. Then things changed to home theater and computer systems design. So I took that route. You go where the money is. Still had a ton of fun (now retired) spending millions of other people's money. I got to build a lot of custom high end computers that were faster than what you could buy, unless they were custom built. It's fun to be back with the High End Stereo systems. Thanks, AUXINPUT for making some interesting reading with your dive into the fuse changes on the amplifiers. Dennis
