Tube rolling on Leven CS 600


Good Morning.
I have a Leben CS 600 amplifier driving Devore O93 speakers.  I am using Luna Mauve ICs with a Linn Akurate DS steamer, Feikert Volare TT, and Cal Audio Icon Mark ii CD/Heed Abacus DAC. The Leben came with 6L6GC tubes, but can also run with EL34 tubes.
Overall it sounds great but on some older recordings ( mainly CD or streaming) its a tad bright/forward; in part due to the poor acoustics of my room.
I wonder if some tube rolling might be worth a try.
Has anyone any experience/thoughts?
Thanks

I've used the GL KT66 in this amp. They soften things a little but also seem to have slightly less in the way of focus with the O/93. It depends on what you are after.
I’ve owned Devore speakers since 2008 including the O/93 for 6 months or so. The mids on that speaker were not for me. I tried a couple amps and the A23 before moving on.
