KT88 tube amp

I just popped the WE 6SN7 in my microzotl and they are exceptionally good with no time. Do they continue to bloom with more hours? 

@ jmolsberg,

Yes, you will notice a deeper and wider sound stage as you approach the 50 hour mark. These tubes just has the ability to capture the very essence of a live performance; other tubes sounds like you are listening to a recording...

^ i figured but good to hear - thank you wig.

 The Shuguang WEKT88 Plus is  my favorite KT88 tube.   In my Jolida Fusion 3502S a quad of these -once properly burned in for about 50 hours- sound absolutely great, with super tight, deep bass, soaring highs, and an airy, 3-D, almost "dreamy" quality to the sound that is second to none.   Very accurate, and in this amp it sounds best (IMHO) with neutral pre and driver tubes: currently a pair of TFK ECC83s smooth plates plus the (cheap but fantastic) RFT ECC81s round getter are doing a great job...

I've had some issues with Shuguang quality control over the years so I'm leaving those off of my list (except for "thetubstore's" preferred 274b as those seem to be vetted) for now, but GL KT77s and KT88s always sound fine, and an old unused pair of Sovtek KT88s recently and surprisingly sounded great in my little SEP amp (and I've got a quad of those)...I tend to stick with 7581As mostly though.
