Conrad Johnson Primier 16ls1 vs 16ls2 owners...

I was hoping to buy a CJ Premier 16 preamp. I want to roll my Amperex white label PQ 7308 small signal tubes. I've heard that the original ART 1 went through tubes quite a bit faster than a normal preamp, which is something that I want to stay away from. Is this true of the 16ls1 or 16ls2 as well? Also, how are the highs and soundstage on both of these fine preamps? Finally, will I lose "bloom" by going to the 16ls2? Thanks! Stan

Chuck, I heard that from a few dealers concerning the original ART only. That's why I'm researching it at this point. I hope to be able to tube roll a bit. It sounds like I need to look into a series 2, judging from your friend's experience with the various pre's that he's owned. Thanks for the help. Stan

'Lose' compared with what?

When I upgraded from the series 1 to series 2 it was positive. The series 2 gets a little more dynamic and neutral. It still has plenty of bloom thou.
Please note that upgrade was only a couple of resistors, most of the upgrade cost went on a new set of tubes and a different power cord ( which you throw away anyway).

Glad I could help. Your question / comment puzzled me since I know quite a few people who are CJ fans and you are the first one I have ever heard make a comment or ask a question concerning short tube life on CJ premier pre-amps.

I can only speak to the version 2, which I have and love. I have used it quite a lot and it was an original demo model on top of that. After more than 2 years and a lot of service easily 1,000 to 1,500 hours a year I have yet to replace a tube. I believe their estimated tube life is 5,000 hours so in a year or so I may consider it. good luck and enjoy the music.
