Just to add my 2 cents worth, I owned them ( Kismet Extremes) for 3 years. They’re very quirky amps. Need to be biased to each speakers sonic signature. Even when this is done there’s no guarantee they’ll perform at their best. Here’s the kicker, unless you learn to do this yourself, you’ll need to ship them back to him to have it done every time you switch speakers$$$. I learned to do it myself after he reluctantly gave me the instructions, but even after I learned to do it, the amps sounded at best, average-good.
They have a very polished smooth sound. Not a lot of depth and bass performance, but adequate. Must be left on continuously or they sound like Crap. Need very long break-in period 500-800 hrs or as he recommends 2-3 months. So if you decide to purchase these amps remember these things are mandatory.
