C-J PREMIER 17 LS SERIE 2 VS 16 LS SERIE 2

Go with a ct-5 or act since you seem to have the money. With all the rest of your component, why stop to an old 16 technology when you can have the best of the best, Put your money where your mouth is. If it was me, I would go with an act without hesitation. With already Dirondo, Cabasse and Jadis in your chain (wow), this is the only logical choice you MUST go for. Believe me, dont waste your money on a 16 and buy the best money can offert. You will have no regret and thank me for ever.

My experience is with the 17ls series I. I have heard the series II but not in my system so my comments are limited to the 17ls I as it compares to the 16ls II. The 16ls II is much more detailed at all frequencies and more musical with a much deeper soundstage........a substantial improvement over the 17. However; the sonic signiture is similar, so if you like the 17 you will love the 16.

As for tubes I use EH 6922 gold pins and feel they offer the best all around performance. I have tried other tubes such as JAN Philips and JJ Teslas but ended up going back to the EH. I have never experimented with what I call the exotic NOS tubes because of their price and limited availability. Hope I could help.

If the 16LS2 has the teflon caps that are in the 17LS2, you may be better off with
the 16. If not, I'll bet the 17LS2 outperforms it. Mine (17LS2) sounded at least
as good in my system as a new CT5 and MUCH better than a CT6. However, I'm
pretty sure the Old Stock Mullard 6DJ8 tubes in my unit -- after a lot of tube
rolling -- are making the most of this peamp. They certainly make it sound a
bunch better than it did with the original EH tubes. For what it's worth. Dave

The 17lsII has the teflon caps the 16lsI or II does not nor does the 17lsI. What limited listening to the 17lsII I did do, it did not seem to have the extension in both high and low frequencies that the 16lsII has, the mid range detail was close.........but in the end (IMO) the 16lsII outperformed the 17lsII. But again this was with limited audition time and not in my system.....so take it for what its worth. Also the MSRP's for the two pre-amps were pretty far apart the 16lsII was about 2500+USD more than the 17LSII if memory prevails.

I'm with Tim here, If you want to keep the sweetness of the prem17 and gain dynamics and musicality, the prem 16 is the way to go.
the CT5 and ACT2 go a bit too far to neutrality for MY tastes but I would go back to a prem 16 any day.
You may notice that cj now have a ART3 using 6922 tubes. Read that want you want between the sound of 6H30 and 6922's.

Nice review on the PH7. You make me want to go out and listen to it. A little more musical meat on the bones, while maintaining the Xono's bass control and quietness sounds almost perfect.
Did u buy the PH7 or are you staying with the Xono?
