Great tubes, great service!
Firstly, many thanks for the snappy service and for goods sent with care and speed. Cheers! These 88s are deadly quiet at idle and make not a sound when powering on or off my amp. So far for reliability they have been superb, and for that alone I give them top marks. They sound good too! I don't think they have any particular magic to them but I think they will make a great reference against which to rate others.
