Krell KAS

Kas power consumption at idle

You can not even think about the cost of power in standby, or you will not enjoy the wonderful sound of the amps.

I sold a pair of 450mcx that had reasonable consumption at standby, and bought evolution ones that spin the meter quite well in standby mode. Higher wattage when fully powered on. The sound difference is over the top. Way over. And I was convinced the 450mcx was some of krell's best work, but the evolution one is it.

In the early 90's I listened to the kas amps quite a bit. They are incredible. Enjoy every day with them as they are very special amps.

Would love to a/b the kas and the evolution ones at some point.

Cheers

Did you manage to compare KAS and the Evolution Ones?

Wonder if anyone else has also compared them?
 
I need some help from someone awesome!
I am an engineer who specializes in repairing high-end audio in Korea.
I am repairing a Krell Cas amplifier, and I am glad to have found this place while looking for a schematic or technical data because the bias circuit is difficult.
Can I ask for files 8326 to 8330 or any other helpful information?
Thanks
 
I have been receiving circuit diagrams and service manuals from the Krell headquarters service support team for some time now, but it is unfortunate that I have not been able to contact them recently.
Does anyone know the news?
 
They are in transition , maybe , maybe not ..!

I have a pair of Krell FPB-300MCX with Krell KCT preamp to drive my Infinity IRS Epsilon with. I now drive the Epsilons with four Krell Kas2 and Krell KRC-HR preamp. There was nothing to compare! The KAS2, KRC-HR combo sounded wau better than the FPB and KCT combo. The KCT, FPB combo drives my Infinity Kappa 9, vertically bi-amped now. Sounds superb)
 
I owned a pair of kas amps when I bought my infinity irsv . Sold them a long while ago ,
Had the CD player and a pre amp .
Sold all except the speakers
have a set of ml no 33 with a krell kct premap
also a krell 700cx
Now down south I have the krell kct and a pair of krell amps .
Ksa200b and ksa 80b on a set of diva apps
all personally recapped .
I lowered the bias on the ksa200b it was just too hot for me . Idle 140 degrees ksa 80b is much more reasonable at 120 degrees .
Idle 6 amps 125 volt
Ksa 200b was 16 amps now 8 amps .
the krell 700cx is at idle about 8 amps but gets hotter as played .
These get cooler on playing a sign of non sliding bias
