OK, I have now had my Prima Luna pre/power combo for around one year and although it hasn't been used very much at all, I am now used to the sound. Way back when, I moaned quite a bit about using it in triode mode rather than ultralinear as I just didn't think it sounded very good but last night changed that for the two of us. We warmed up the system and started listening to an album on CD by Greyboy but this time at a fairly low level of volume. I then switched it to triode mode and it sounded bloody glorious. I can only deduce from that, that it doesn't like playing in triode mode unless the going is good. My next attempt will be playing vinyl in triode mode. We think that maybe we should try out a bit of Quantic, maybe the 5th Exotic on vinyl. Looking forward to it.
