I’ve deliberately delayed submitting this review to let the amp settle down and bed in but I’m very impressed. The control and clarity that the amp now has would cost an awful lot of money if buying new but this is achieved without sounding clinical just smooth authoritative powerful sound it’s an addictive mix. I’m now scouting the second hand market for another P150 and if I find one it’s going straight to John for him to work his magic.
