Rogue amps-- try 5751 instead of 12ax7

I am going to try kt 120s on my rogue m180s next, I have gold lion 12au7s and 12ax7s on the way from rogue , should have them in a couple of weeks, but I was interested in the kt77s, what do they sound like? has anyone compared kt77s vrs kt120s? thanks, Chris

Here's a copy of what I posted a little while back concerning my "tube swapping" for my Rogie Audio Cronus. Mark and Nick at Rogue have always been extremely helpful. My system makes beautiful music.......

For me, my Cronus, being fed by my Rega P3-24/Exact 2/TTPSU and Rotel RCD-1072, through my Vandersteens, sounds better after I did the following : an RCA NOS 5814 to replace the center EH 12AU7 gain stage tube, a pair of GE NOS Five Star 5751 "goldpins" to replace the Sovtek 12AX7 input tubes, and a pair of GE NOS 12AU7A's to replace the EH 12AU7 driver tubes. I then replaced the original Svetlana EL-34's with a beautiful matched quad of Genelex Gold Lion KT-77's.

All this "tube rolling" was done after some pretty nice conversations with Mark and Nick at Rogue Audio, and I'm glad I followed their advice. They are a pleasure to work with.

So, Dhcod..... I'm glad you're enjoying your Atlas. Happy Listening !

I use GE triple mica black plate 5751's and made a big difference in my Tempest II. The Sovtek 12AX7's sounded fuzzy and the GE's sound much more focused and clear.

Hi Facten,

Just to make it clear, I was talking about KT77 not KT88. KT77 are an exact equivalent of the EL34. I have no experience regarding Genalex KT88.

Since you suggest me the Shuguang Black Treasures El34, I'll consider them and maybe give them a try someday.

Sebastien1 - yes realized you were interested in the KT77s not the 88s was just trying to give you a sense of a possible alternative based upon what I'm hearing when comparing the 2 KT88s - enjoy!
