I own the Krell xd 300 and the Illusion preamp with a pair of B&W 700S3
I used to own the 700cx along with the KPS25sc they were great units i had the 700cx recapped before i sold it that ran about 2K\
I really like the ibias setup with the illusion paired to my xd 300 that has the sabre dac installed in the pre-amp which by the way only weighes around aprox 80 pounds where as my 700 cx was over 200 pounds to ship and Krell has limited replacement parts for the KPS25sc as the acrilic top pins are very easy to break and there own test cover in the shop has a broken pin
on it and i had to send it overseas to i believe Creoe who has a jig to replace the pins that are so easily broken there are limited parts on the cd drive so needless to say after 20 years with my old system it was time to go and i really like they way the ibias switching works keeping the amp in class A mode so i completly upgraded my system last year and I also use the Siltech silver cable through my whole system
and krell makes mo0re than 2 amps for example
