What I mean by noisy is tube rush when used with LOMC's. Using only tubes for 60db+ of gain is very difficult.
I am sure owners of the IO will chime in giving you some options of NOS tubes to reduce or remove this effect, however with the stk tubes i could clearly hear the tube rush in between songs and during quiet parts of songs.
