Early listening is very promising, the speaker terminals are screws that can hold spade ended cable. As usual the CD player is my Sony 505ES, preamp is a DIY solid state unit, and the speakers are the JBL 2 way 4331s. I do still use a pair of 18″jbls as subs when needed, but the sound is pretty good with just the 15″” ( 38cm) cone type JBL2231A, and mid-high horn type JBL 2308+2312+2420.
I have ordered more RCA valves as the existing valves are getting tired. Still, the sound is pretty good and quite tight, no sloppy bass or rolled off treble. More listening underway!
