KT88 in Rogue ST-100 amplifier


Anyone experimented with the KT88 tubes in the Rogue ST-100 in place of the stock KT120?
Any thoughts? What was the change? Did you notice the decrease in power? Change in resolution, details,  dynamics, soundstage, etc.?
Speakers are Martin Logan Montis with powered woofers. Preamp is Pass Labs XP-12. 
thanks!

What are you lacking with the KT120?  I much preferred Gold Lion KT88 when I had a Primaluna integrated over the KT120 but that's a different circuit. The KT120 were very powerful and dynamic but lacked in midrange richness. Very analytical and almost strident. They didn't last long. However,  they may be the best tube for your amp if Rogue designed the amp around that tube.
