Odyssey Kismet Reference series.

@hiendmmoe ... Interesting post.  This may explain why a rough patch in the 5 to 7kHz range, which I had attributed to my speakers/room, turned out to be from the Odyssey amp.  The sharpness in that range vanished with my new amp.  Perhaps the Odyssey amp was never biased properly for my sprakers.  Another reason I am glad to have moved on from my Odyssey amp.  I am not a tweaker type; I want to listen to music.  If I wanted to fool around with bias settings, I would have gone for a tube amp.

They are NOT biased for your speakers, Klaus sets the bias based on the voltage coming out of your outlet which he asks you to check prior to his building the amps.  People need to get their facts straight instead of passing the wrong information.

I've owned the Kitargo mono extremes for about three years and have had zero problems with the amps  I'm currently running a pair of Ruark CL30's and they sound great.  Prior to this purchase, I owed Arcam amps which left much to be desired. Over the past three years of dealing with Klaus he's been excellent.  His customer service is the best, and he returns my calls and e-mails promptly. We've spoken several times at the Capital Audio Fest at length.  Presently, I'm in the process of upgrading to the Kismet monos and looking forward to it.  

I had issues with the products and finally moved on to Modwright to distance myself from them. I believe he is just too busy to do the quality control that is supposed to be done. Many people (obviously) have had good experiences with him.

Yes, Klaus does ask you to measure your voltage and sets the amps to your voltage, but he also sets current bias to your speakers. The range for that is 18-28 millivolts. I owned them for 3 years and glad they’re gone.
