Primaluna and Rogue

Thanks for all the great feedback. I'm amazed at how beautiful the amp sounds. It's going to make the winter months that much more enjoyable. As I don't know much about tube amps, I was wondering if you could answer a question. If I pull the power tubes out, should I bias them when they go back in? The reason I ask is that since it's a used amp, it was shipped to me with the power tubes out (only signal tubes in). When I got the amp, I just put the tubes in their proper locations (he had the boxes marked) and turned it on without biasing.

I would check the bias just to be sure each tube isset right - its simply and easy on the amp to do - let the amp warm up for 30 minues with the volume turned down then check it - after that check it 1x a month

I don't know the Rogue amps, but I own the PL 7 monos. They are reasonably powerful, very fine sounding, extremely versatile (easy tube rolling w/auto bias), well built amps - especially for the $. If you can visit the PL importer, Upscale Audio, which is located about an hour outside LA, you can hear the entire line-up.

Good Luck

BTW, I've settled on the KT-66 as my preferred output tube when I use these amps in my system (usually driving Merlin VSMs).

Thanks Marty, based on yours and a lot of other responses, I will have to give the PL 7's strong consideration, even without hearing them. I think it will come down to what I can get used on Agon, while springing for a new PL pre-amp. But we will see where my head and pockets are at after Christmas! :)

I love the sound of my PL 7 on my Soliloquy 6.5 (91db) speakers. I tried driving these with a PL 5 and although it sounded grand, the bass has more authority and control with the 7s.

Tube rolling is critical to get the sound you like.
