I'm using Cherry 180 with Tungsol KT120s to drive my behemoth Usher BE20 no sweat. I did quite a few upgrades to my VTA180 like volume pot, Duelund cap coupling, signal path resistors, etc
Worth noting that I try using Psvane KT120s. Sound superior to Tungsol but reliability is suck! Several tube failure during break in, each time would cost me to send bad tube back to Canada for replacement. Finally, dealer offer me to return Psvane of another set of Tungsol. So don't use Psvane KT120s, you will be sorry. Lot of headaches and maybe heart attack because when a tube goes south, big kaboom from your speaker
