Satie IS an audiophile (purist analog lover, with a tube amp on the M/T panels of his Tympani’s), and the Crown he has on his T-IV bass panels is the discontinued Macrotech 5002VZ. He advises against the cheap and popular XLS line, so maybe I can find a 5002VZ used.thanks to you bdp24 for introducing me to these Crown amp. :-) I got a hold of 2 2402 models to use for my bass panels in parallel mono mode. I was advised to use the amp in parallel mono mode due to the speaker low impedance & that the amp was rated to drive this sort of low impedance in parallel mono mode only.
In stereo mode (in another 8-ohm system) the amps sound very nice & seem to have very nice bass drive.
Two things to watch out - these amps are very heavy. The 5002VZ that Satie uses is 80lbs atleast & the fan noise. One cannot operate them w/o the fan - it wont even turn on. They are pro amps hence the designers knew that people would kick the shi$ out of them hence have put many safeguards one of which is a continuous fan. At those stupid-high output powers it is required, I'm afraid. One has to come up with a plan to deal w/ fan noise. I'm working on mine....
