Tube favorites for Modwright LS100?

I must add an addendum to my LS100 tube review above. After spending a good deal of time with the Black Treasures I decided to try the Sophia 6SN7's as suggested by Dan Wright on the Modwright website. I must concur with him (and others), that the Sophia tubes are absolutely wonderful in all respects, bettering even the very good Black Treasures. I must (somewhat sheepishly) now recommend that you try them in any piece of equipment that calls for the 6SN7 tube. They really are quite special, and reasonably priced to boot.
Happy listening!

I just received my LS100 installed NOS 1963 Tungsol 6sn7 and a NOS Sylvania GZ34. Down the road I'll try the BTs (have a quad of BT KT88s in my Ayon Spirit and really enjoy them) or the Sophias

I have about 100 hours on the LS100 which I understand requires at least 400 hours of break-in to reach their intended sound. Have liked the sound of the NOS Tungsol and Sylvania as they and the amp have been working themselves in, but decided to go ahead and pick up a pair of the Black Treasure CV181s. Will say that with only about an hour on these tubes they already offer more top to bottom detail than the Tungsol's. Will look forward to trying the Sophia's at some point.

Anyone try the Synergy HiFi/Create 6SN7's and/or 5AR4 in the LS100?

I am auditioning a LS100 with stock tubes.

I find the top end a little hot, bright, slightly harsh.

My reaction may be due to my age and too much rock and roll in my youth, my hearing is down quite a bit at 10,000 hz and higher.

Do you think upgraded tubes for the LS100 will tame the top end or just add bass and expand the sound stage.

Thanks
