Mark Levinson No. 20.6 vs. Krell KRS 200 vs. Krell KAS

Hi Everyone:

I am PERHAPS Contemplating Selling My ML No. 20.6's to Purchase a Set of Krell KRS 200's which I have always wanted. I am though Very Satisfied with the Sound of My 20.6's and I am afraid, that although the KRS 200's will undoubtedly improve the Bass Area, that this improvement will come at the expense of Fine Micro-detailing, where I believe, that the 20.'6s are some of the best amps perhaps ever produced.

I am from Europe, so I would like a 220-240V Version of the KRS 200's, Which is also what I have read, gives the best results sound-wise. Regarding though, which Power-Installation I should install, then I would like to ask, that since these Amps have a Power Consumption of 160Watts EACH, what kind of Breakers should I install in my house? I've heard, that if you install too small Breakers, then they will either have the Breakers cut out or they will sound too "Thin" and/or  "Hungered" for more Power. But what are "Too Small" Breakers? Would a Dedicated 20 Amp Breaker for EACH Amp be enough? I could install both 30, 40 or 50 Amp Breakers, but I have to say, that I Very Rarely Hear music at Loud Volumes. I Prefer to sit late at night and hear music at fairly low levels, so the question is, where to stop Breaker-wise? Perhaps both 30 and 40 Amp. Breakers is still Recommendable as well as Wise, but the question is, whether a 50 Amp Breaker for EACH Amp, isn't Overdoing it??? What do you guys say?

What is Your oppinions about this? Have any of you heard both The 20.6's and the KRS 200's either together side by side or with some time-span in between?

Another Question is regarding the KRS 200's in comparison to The KAS's. Some say that The KRS 200's are The Best Pure Class A Amps, Krell has ever made, but how does it compare to the KAS's, which have Sustained Plateau Biasing instead?

Any and Every Comments and Experiences are Very Welcome.

Have a Great Audio Day.

Sincerely Thomas.

Hi rcprince:

Thanks for your comment. It may be, that the 20.6's are a little on the dark side, although I certainly don't feel that way. In comparison to my Stax DMA-X2's, which I has between 2006-2009, they were a Significant Improvement in casting light on the soundstage. The Stax's were MUCH Darker in this Discipline.I feel the 20.6's cast exactly the amount of light onto the soundstage as they are supposed to and I don't feel, that I miss out on anything there. They have the exact same brightness as my Pass XA160.5's I had between the Stax's and my 20.6's, so I feel they are very correct in this aspect.

I don't think the KRS's will do much in that direction either, but it'd still be an experience of proportions, to have them standing in my livingroom, but I believe, that it should NOT be at the expense of my 20.6's as they are and I believe that they will be for a Very Long Time, My Ultimate References at which I Judge Other Amps.

Have a Great Audio Day rcprince.

Sincerely Thomas.

I bought the k'RS 100s some years ago. Comparing them to other amps I own they are definetely better sounding than the KRELL KSA 300S the ML 333 and 335 and even the 33H. The only amp from the ones I own that can compete with them is the Krell FPB 600 but only after caps replacemennt (I believe 128 of them...) with nichicon gold. I am now having the caps and bridges replaced of the KRS 100. If you are interested I will let you know of the outcome.

No matter the brand, I too, enjoy a high current power amp.
There is no substitute.

Hi panprot19:

Sounds Very Interesting with your KRS 100's I've heard, that they should sound sweeter than the 200's. Do you know how much they weigh??? It's something around 80 kilos if I'm not mistaken.

That they should beat the 33H's is certainly something. I've seen a pair on youtube, I believe the owner is from Finland and he drives a set of Apogee's (I Believe They are Scintillas, but I'm not sure) and it sound pretty good on the recording.

Yes Please let me know, when you get the caps and bridges changed, but what it "nichicon gold"???

Have a Great Audio Day.

Sincerely Thomas.
