The two front driver tubes will have a audible effect on sound quality. I've settled on NOS Amperex orange globe (Holland) a-frame 6dj8. Very smooth but still detailed.
Clio09, are you alos using a passive? I just got a "Pot-in-a-Box" from Roger ($135)and I'll be darn it sounds really good. Better than the Joule? We'll see, I need some time with it, but it is a steal based on sound.
I used my K&K Audio TVC with the RM9 and it was a great match. This was back when I lived in Santa Barbara and was able to visit Roger to have the RM9 upgraded to MkII and found he prefers it with a passive pre. He ran an RM200 with the pot in the box with his new electrostatic speakers (these are phenomenal for the price). A great system. I wouldn't be surprised if it gave the Joule a run for the money. I sold my LA-100MkIII when I got the K&K TVC.
I no longer have the RM9 as the guy I bought it from bought it back from me. However, I am considering a system reconfiguration and trying a set of new speakers that may be a very good match for the RM10. Rogers amps are excellent.
