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

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).

If the unit was upgraded on the back of the chassis cj provided a sticker that basic stated series 2 and the date and maybe a new serial number ( can't remember that clearly).

Not sure on new units, however I am sure you could ask cj at what batch of serial numbers series 2 started if it is not on the back panel.
