Question for ARC VT 100 Mk II owners

Are any of you using KT120 output tubes in your VT100 ?
Please share your experiences. How do they sound? How about tube life?

I got 800 hours on the tubes and everything is working perfectly. I love my amp but always felt the low end was a bit week. Not so much anymore. When my friend heard my amp with the KT 120 he said " shit, solid state lows". It sounds more robust and powerfull.
