The Amps heaved a huge sigh of relief at their first play of jazz...
And fortunately they all work absolutely perfect...so no difficult questions for the moment
For anyone else interested in Kerrs the difference between passive and active pre amps used with them is huge....I'm sure Paul from Camden noticed the look on my face when we took out the passive and replaced it with a Croft valve pre amp....the music just came alive and burst out of the speakers.
