” The treble extension is much more natural and doesn’t sound coaxed or pushed thus creates a natural roll out rather than a forced impression. There is virtually no sibilance to presentation of the upper frequencies while there isn’t much in the way of harshness to the mid-range either. The Sovtec tubes still had a bit of hardness to the mid-range so the change in tubes is welcome addition rather than a subtraction.”
