Help with Krell KSA 50-S versus Krell KSA 200-S



KSA 50-S versus Krell KSA 200-S likes and differences??

Hi
I ownd a little Krell KSA 50-S years ago back in the nineties
I ran it with a Krell KRC-3 preamps into Totem model 1 speakers
the sound was really very good, sounded like a tube amp
and even though the amp was touted as no bass, there still
seemd to be quite a bit, at least with those speakers anyway
My reason for writing is:
I have no system currently but want to purcahse a system again and was very happy with this sound , was thinking of searching for a used Krell KSA 50-S, I have already forund a mint KRC-3 preamp. I had heard that the KSA 100-S was un kind of unremarkable, but wanted to ask any Krell guys (or gals) with experience if the larger Krell 200-S at all mimicked the sound of the Krell KSA 50-S, with the sweetness of tubes in the midrange and large dynamic floor and depth, or is the Krell KSA 200-S like a completely different animal, i.e., more solid state sounding, with virtues of its own.

The mono version of the KSA 80 was the KMA 160. KSA stands for Krell Stereo Amp. KMA stands for Krell Mono Amp.
Oops, sorry, you're right, I meant the "big brother" of the KSA 80. Same generation Krell. And FWIW, I thought the 80 sounded just a little better than the 200.

In stereophile they generrally compare ksa50s to ksa100but there is part were they compare ksa50s to ksa100s and they said the same as people said here but about ksa100s that ksa50s sound more sweet. I HAVE ANOTHER QUESTION.

DUE TO AUTOMATIC  BIASING ADJUSTABLE LEVEL DEPENDS FROM INPUT SIGNAL  CAN SOMEONE HEARD SOME PUMPING ON BASS FREQUENCYS ON SOME KIND SLOW BASS OR SOMETHING? I ASK BECAUSE INPUT LEVEL MESSURE CIRCUT HAVE TO STILL SOME PART OF INPUT SIGNAL AND IT SHOULD IMPACT DETAILS COMPARE TO AMP WITH FIXED BIAST. MAYBE HOW AVERYBODY CLAIM A LITTLE LACK OF BASS IS COUSE BY THAT AUTOMATIC BIASING CIRCUIT?

The sustained plateau bias does not effect the bass, my ksa 300s amplifier has great bass performance. 

In a similar situation, on a secondary system setup - my Pass/Forte' amp was configured in two ways, either Class A/B 180w or full Class A 50w, constant on. 

While all of my former amps were Class A/B 200w SS, and used them to drive my former Totem One Signatures, while they sounded good, I now have the Pass Forte' configured as true Class A 50w with larger and more demanding speakers. It does sound sweeter, and does a fine job controlling the drivers at low to moderate listening levels. Speakers and the size of the room matters too.  

My primary system is all tube, and so it's fun to compare back and forth fwiw
