Hi bullitt5094,
This is my final attempt to try to explain to you why you owe to your self to at least hear a SET amp on the DI's.
Klaus' amps are quite good, and great bargains for the money, however they do not compete sonicly, in my opinion, with the latest generation Pass Labs XA.8 series, Perla Audio, and even with many of the First Watt amplifiers. I have owned all of these great amps, yet they still can't do certain things like a SET amplifier.
No SS amplifier presents the music like a SET amplifier. I could get into the liquidity, color ,tonality, flow of the music that is quite magical with these simple circuit designs, but you really have to hear it for yourself, no words can replace actual experience. Your DI's give you the opportunity to try one out, if its not your cup of sonic tea, so be it. Historically, I loved the sound of SET's, but hated almost all the speakers that you had to use with them ( Horns and single driver designs) that had flaws and shortcomings for my taste.
Now, with the DI's which are reference level transducers with virtually no flaws you can use SET amplifiers with a full range highly dynamic box enclosure speaker which did not exist at this level in the past. I'm sure there is a way, hell you can borrow my Cyber-30, so at least you would really know how different the experience is between SS amps and SET amps.
