@larry5729,
No one was asking about your impression of the speakers, he already owns them, so why diss them?
I had the original Cronus Magnum with the KT120 tubes.. I tube rolled, had 2 Mullard NOS 4003 tubes and can't remember what I went with for the other 3 tubes. I always felt the sound was a little bit grainy and found it to be the KT120 tubes. I tried EL34 tubes but didn't like the too polite tone. I sold the amp after a year.
