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 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.

Good Day Thomas- OP-

I am in a period of building my reference system. Check out my thread here on the 'Gon, Thiel Owners.

I am building my reference system around a very sweet pair of Thiel CS 2.4SE loudspeakers.  Brands of interest, some I have auditioned and others not as of date;
Aesthetix
Audionet
Audioquest
Audio Research (ARC)
Bryston
Cary
Classe'
Conrad Johnson
Esoteric
Krell
Lamm
Mark Levinson
Naim
Nordost
Oddessey
Parasound
Pass Labs
Pioneer Elite
Primare
Threshold
Silent Source
Sony ES
Stage III Concepts
Yamaha....
...just to mention a few...

Hi jafant:

Wow, that's quite a list. But all of the different brands you mention, make different gear. Pass Labs is mostly amplifiers, together with Krell, Where Sony ES can by almost anything, from amps to CD-Players to Vinyl, so what are gonna put where and what do you have as of now??

Hi Dave and Thomas,
The work on the amps is carried out by a very good technician in Athens/Greece were I live. 
I  don't know the weight of the 100's as I do not have the manual and could not find any info on the net about them. "Gold" are the audio grade electrolytic caps by nichicon with affordable prices. They have really transformed the fpb 600 (which is one of the worst amps krell produced - slow and "muddy") to a really super fast analytical amp. As I have read the KRS's were built specificaly for Apogee's, that should explain the need for sweet sound. There is german guy who drives the huge apogees "The Apogee" wth 4 KRS 200 only for the bass and lamp amps for mids and highs.
In any case as the amps are old I believe a caps replacement is a must.
