Hi GWALT, thanks for the input on your JA30! You have some really nice equipment and a great-looking room…….appears to be quite a large space as well, does the Jadis have any issues energizing it? Also, I didn’t see what those red power cords are in your system details? Could you also share what type of music you listen to?
My situation is a bit different; smallish medium size room, driving 87db electrostat hybrids (Janszen) currently with a Rowland amp. Some folks have reported finding bliss with these speakers and lower powered tube amps, and I was quite impressed with the Jadis I50 integrated amp equipped with KT150 tubes at the most recent Newport show. Just trying to get some idea as to whether the JA30 MK II with KT150’s would be sufficient in my room, though will likely not be able to audition these mono amps in the USA unless one of the few dealers imports one which, as far as I know, has not happened (yet). As you indicated, correct matching of speakers & amp is critical.
