Just adding this list to help out anyone who may stumble upon this thread.

The following is a list of ARC amps that are authorized to use the KT-120:
VS55, VSi55, VS60, VSi60, VS110, VS115, REF110, VM220. I hope people find this useful as there seems to be a lot of confusion about it.
Thanks for sharing your thoughts about th KT-120s. Good to know about the slight loss of top-end detail. I like a bit of detail in my music but sometimes I've been hit with a bit of harshness fro the highs with some of my previous systems. Are your KT-120s matched from the factory or cryo treated? I'm just curious since I've found there to be about a $25 difference in pricing of quad sets of KT-120 tubes from various e-tailers. There's also a place that has a premium matching service for these tubes. A quad is about $200 as well.
Thanks for these insights on the KT120 tubes.
You mentioned at the start that Chris did some upgrades on your SFP2.
Just wondering: did the upgrade include just the new tubes? Or were there some other component changes? Caps, Resistors, Wire?
I’m just thinking that perhaps the new tubes were not solely responsible for the sonic gains you realised? Maybe it was the other upgrades?
What else was changed, before you received the retubed amp back?
