Upgrade Krell KSA 250 to what?


Here's the situation:

My 30 year old Krell KSA 250 (upgraded/hot rodded at the factory 20 yrs ago) is showing signs of age.  I'm having trouble turning it on/off and I'm afraid it needs service.  While I've enjoyed it tremendously I'm naturally wondering about replacement in lieu of spending significant sums on updating it.  Furthermore, not sure if the Krell factory is willing or capable of servicing an amp of this vintage.

So I've been toying with replacing it with a new or nearly new piece.  Options I'm considering are Pass labs (possibly X250.8 or 350.8), ARC Ref 75 SE or possibly a Ref 150 SE (used), or similar.  D'Agostino dealer is nearby as well along with a VAC dealer but both those brands are too rich ($$$$) for my blood.  Trying to stay below $10K, preferably less than $8K.

The system for this change is composed mostly of older gear, as follows:

Wilson Watt/Puppy 7

Sota Star III/ SME V/ Benz Ruby Z analog front end

Oppo 105 digital player

ARC Ref 2 Mk II line stage

ARC PH3 SE phono

Straightwire/ Cogelco/ Purist Audio cables


Thanks in advance for the input!

In the mean time
My fav amp was a Kinergetic KBA 75, but I killed it swapping out power cords before the caps drained. Since then I have owned tube amps, and many class Ds. None of them compared, BUT...


About 7 months ago I bought Ric Schultz's EVS 1200 (dual mono XLR only class D using newest IcePower 1200AS2 modules, which he then mods

MSRP ~ $2300

I use it direct from my Oppo 105 with upgraded Linear Power Module and upgraded IEC with Furutech rhodium and heavy gauge pure silver wire (both from Ebay(. He offers a 30 day money back

You might keep it as a backup, and to listen to shhould you spend the $$$ to repair the Krell

The Krell was a Bi-polar output classic, able to "almost" keep doubling it’s wattage down to 2ohms, they had a bit of Class-A bias on them as well about 12w. You obviously like what this sort of amp does grunt wise.

Go even better with the new John Curl designed Parasound Holo JC1+ monoblocks, they do the Krell balls to the wall thing and will sound great even better than the older JC1’s did.

And your Wilson 7’s (best watt/puppy made) will love the JC1+ current ability and drive, also you can switch them into high Class-A bias for even sweeter more transparent upper/mids and highs. And your on the money with them
