In Reply to: RE: Question about Krell amp models posted by George S. Roland on January 22, 2015 at 10:23:41
I had a conversation with Dan D'Agostino a number of years ago and he claims that the KSA-250 is one of the best sounding amps. that he's ever built. I love mine and would never consider replacing it.
Follow Ups:
I'd be curious to know how much power that KSA-250 truly draws from the AC mains while sitting there idle. Have you ever measured it with one of those inexpensive Watt meters? I would love to try one of the old Krells again someday but probably not in the summertime. ;-)
I thought my baby Krell KSA-50S was an incredible sounding SS amp. The only other Krell amp that I've owned since then was the KAV-2250 which was painfully dry and harsh. It had kind of a gray and sterile sound to it, lacking any soul and killing all musical enjoyment, almost like my 7BSST2 Brystons I had but these newer Brystons were at least smooth and not grainy like the KAV-2250.
Kill A Watt power meter. $20 USD
There are various models of this meter with additional features but the basic model is more than sufficient to measure the power consumption (in Watts) for electronics and appliances around the home.
Hello Abe. I have measured mine many times over the years and it consistently pulls 12 amps at idle. It is on a dedicated 20 amp circuit. There is nothing else on that circuit. It does a pretty good job of heating the room (26'x17'x8'). In case anyone doubts the validity of your numbers and those advertised, the KSA 250 went thru a change during its life. People complained about the heat and Krell reacted by lowering the bias. My amp is the high bias. You can tell by looking at the back of the amp. The location of the binding posts are different. Everything else looks the same and there was no model identification change.
What year was the change , i had two and the only one had that high a bias was the ksa200, Stereophile's test amp was also low bias (28 watts class-a) ...
My purchase order was dated 8-16-1990. SN# 6735. Bias was cut back sometime after that date. If you need more specific information, I'd suggest giving Krell a call. If you're in Michigan, you are welcome to come over with your VOM.
More clarification :
[11 amps is much too high at idle. It should be closer to 2 or 3 amps and will then proceed upwards as the volume of playback increases.Patrick Bresnahan

As confirmed and measured by Stereophile, Did not confirm if there was a model split....

Boy---this is really bugging you isn't it. Are you anal or just want to be King ? I happen to know Patrick very well but Dan is the guy that built my amp.
Projecting ?What information hurts, I also know the parties involved and really, so what, others should go by you only, wake up lunchbox, it's not a cancer cure, so save it, your beef is with Krell and stereophile, but go ahead, make it personal while sprouting off more dis-information ...

I don't have a beef. I was talking about my personal amp. which I've owned for the past 25 years (unlike you). You were challenging the validity of the specs on "my" amp.
I wasnt challenging anything or anyone, you were the one who decided to make it personal, my only intent was providing data I'm aware of after owning and using Krells over the years and pay close attn, Krell confirmed my assertions, so did JA in his stereophile test, just because you have one that doesn't fit, go take it up with Krell and i never disputed your take, i said i was not able to confirm nor deny, with basic english comprehension that means it stands, that early versions may be biased like the older KSA200 and later versions not , as tested by Stereophile , i dont know, i can tell you its more likely that one is out of whack if it measures 11 amps than not, maybe Dan biased yours that high , i dont know and frankly dont care.As to my experience with Krells over the years ,
KSA100
KSA300
KSA200
KSA250
FPB300
FPB300cx
FPB600cxSo your 25yrs with one amp means nothing to me, I was only providing information that may or maynot benefit others, not some head in the sand bunk.
Now go call Krell up and straighten them out, apparently they dont know what they are talking about, email Atkinson too .....
Regards.
PS: you should try lowering the bias on yours, you might be in for a suprise..

Sorry, not my fight, but if you both want to get all hot & bothered over details, I'd just point that one out.
Krell DID make an MDA 300 (mono version of the KSA 150, which was a great amp.)
Krell also made a KSA 300S - one of their "Sustained Plateau Biassing" series of amps. This was also a pretty nice amp.
BUT, they have never made a KSA300 or KSA 300 amplifier.
Yes, KSA300S, Typo, semantics really , left off the S designation, kinda like you saying KSA300 twice ... :)

A.WAYNE----You know what----I apologize. I'm an old man and the older I get the more I let things get under my skin. Don't know why. I'll try to do better.
Denden11,
No apology necessary , these things sometimes get carried away , in my laziness in typing i may have not expressed correctly what was discovered and may have given you the impression i was discarding your input , that was not my intent.
Regards
