Would anyone be willing to hazard a guess, or even better,  supply some measurements and data on the power output of the Kismet monoblocks at 2 and 4 Ohms? I'm about to get some Wilson Sashas and apparently they spend much of their life in the 1.8 to 4 Ohm world.

Hi Nicholas ... 
I use Infinity Kappa 9a with my mono blocks stratos extreme ... 
these speakers are among the most difficult driver ... 
descents at 1 ohm ... just see below ... 
the stratos have so far fully insured ... 
but I never pushed to the bottom ...
Sonnora volume is already very, too hard to see 3 / 4 ...
 now, I listen more my JBL studio monitor 4435.

IN FACT, how will you pay your sasha ?????????????? 

in France, the price is astronomical ...

[Nicholas Bedworth]

Thanks for the report. The Sashas are presently in the harbor here on Maui, ready to be offloaded and delivered shortly. They're arpund $29K with shipping, special paint, tax, etc., which isn't too bad by current standards.

How much are they in France? Tu es francophone, n'est-ce pas?

Are you saying that the mono block stratos extremes will drive a 1 Ohm load OK? That's encouraging.

hi Nicholas...
yes , i'm french...

here 's the link to have a look on my different set up...

stratos mono extreme with KAPPA 9 A , no problème at time...

and they fall down 2 , or 1 ohms , sometime...  

for sashas , i'll have not price now , i'll tell younext time ...

mono extremes will cruise along in a one Ohm load for hours and hours at about 1000 watts

Gary,

Thanks! The Kismet monoblocks have a single transformer. Could you make a guess as to their output at 4 and 2 Ohms? And could you share your measurement methodology, so I can try it myself?

The Sashas are around 91 dB sensitivity, and are way more sensitive than my Usher Be-718s, which seem to be around 84 dB.

I was a bit taken back when I read that the Kismets have only one transformer, so I looked at the pics of my own pair (it's too late to be removing the top of the case now). You are right, but it IS one MOOSE of a power trannie! Looks to be fully the equivalent of the two that are paralleled in the Stratos Extreme. Klaus is hard to pin down as to specs with most of this gear. He told me the power rating would be 'somewhere between' the regular Stratos monoblocs and the Extremes. Think he tends to....extreme conservativeness (is that a word?). Guess he'd rather do that and have his gear outperform our expectations, which it usually does.
   I wouldn't give it another thought. Your Kismets are up to driving about any speaker on the planet, is my guess. Let us know how they sound with your new speakers!

[Nicholas Bedworth]

The transformer in my Kismet in Stratos cases is about half that size

Then mine must be a double. Makes sense, because the owner I bought these from said he got 'all the bells and whistles'. Plus, there's no WAY these things are only 60lbs each! Took 3 trips to the chiro to get my back put back in place, after muscling these beasts up the stairs to my condo.

There is a post out there somewhere where Klaus tested a board to failure.  Took a hell of a lot of punishment, if I recall.  No worries at all, these amps will take a tremendous amount of current prior to failure.

[Nicholas Bedworth]

The reason I need to know is that the amplifiers are often used for reviews, and it's nice to be able to state the output at various impedances.

And because the Wilson Sashas are quite low across much of their bass range, high current into 1.8 Ohms is important.

Call Klaus, let him know what you are doing (congrats on the 6Moons gig), and he'll most likely give you the data.  I know he told me they will run all day at 2 ohms, but that doesn't help your situation.

Nice review on the Weiss.

[Nicholas Bedworth]

That they are apparently very stable into 2 Ohms is my only concern, although some data would be fun to have as well. The Sashas are very nice indeed, probably 1/2 to being fully conditioned.

I'd guess 750+ watts, if not 1000 watts.

once again your using Kissmets, and all the data I know of is for a Stratos! But a Stratos is stable in a one Ohm load for a long, long, long time. Yet it is in my own personal opinion that they sound best in a very high loaded condition.
