Which Krell to hunt down on the used market?

I found the older Krells grainy. I also found the sound difference between the FPB 200, 300 as compared to the 600 much more than just the power. The FPB 600 is IMHO a much better amplifier than the lower powered units. I ended up buying the 600 after comparing. YMMV.

How do the older very expensive Reference series KRS 100, KRS200 compare to the newer FPB series? Bob

Personally I like the KAS2. To my ears, they have both positives of FPB and KSA S Series. It is definitely better than KSA300S I have heard in every aspect, yet it has treble trasnparency character that FPB cx series has but in a lesser extent. For all new or old series Krell amps, I strongly recommend to give them a dedicated 20A line per amp. If you haven't done so, give it shot for a great treat. You may also conclude that it doens't sound anything like the anemic Krell sound that many have been complained about.

Slightly off topic here but I am guessing you all might know the answer:

Do the older Krells, like the KSA series or the early FPB series, have a remote trigger for turning it on and off?

I have searched for user manuals on-line, but have not found anything but the current model's information.

Thanks.

Just upgraded from KSA-200s to a FPB-300cx. I'd say the quality is up not down. The cx is much more musical. I recall the old KSA250s were very harsh but super dynamic and wonderful in the lower end.
