Anthem Pre 2L tube rolling question

Yes, put the good ones in front. If there is a difference, this will be an improvement, although not as much as with preamps such as the AI M3a where 2 are for the linestage and 2 are for the phono. That's what SF used to recommend. I swap out all 4, but I dont get real exotic. Tube life in these preamps is pretty long, not at all like the AI preamps, so I don't worry about how long they last.

I used to own the Pre2L and have upgraded to the Sonic Frontiers Line 2 preamp. It is the rear tubes that have the greatest effect on the sound. This was conveyed to me by Kevin Deal (where I bought the Pre2L and an Anthem/Sonic Frontiers dealer) and he reiterated this at another audio forum. I believe he said the rear tubes will get you 80% vs using the same tubes in all 4 positions. My personal experience is that life is too short, and I use Siemans 7308's in all 6 positions of the Line 2. BTW, the Pre2L is an excellent preamp and very underated, as long as you don't mind living with the sensitive remote volume control.

Hmm, that's a problem because I thought for sure Kevin told me the opposite, unless we arent talking about the same front. I could be mistaken, and as I said, I just swap all four. I'll see if I can raise him.

I've been wondering the same thing for my Pre-1L. I'm about to start tube-rolling and would like to save time/money by swapping in pairs rather than quads. Are the two pre-amps the same as far as tube position?
