Product Reviews
These are good souding,super reliable KT88's. Do they sound as good as 1968 vintage British made audiophile tubes? no. but if you also compare how much your paying, these sound more than good enough to come out ahead in that comparison.So there, Electroharmonix KT88 tubes are actually even better than MOV's.
