Yes with John Rutan
He used a new audible illusions pre with a pass 250.5 amp and a wadia cdplayer with the quattros
it was amazing,, truly. no power conditioning and some treatments
the 5a's had all acoustic research stuff, Big 100 watt stereo amp , some pre with big digital numbers for the volume and a ar cd player, sounded very great. it was perfect in fact, probably the best i ever heard, he had some ar mono blocks too but they were not being used,
he is very good at setup Richard gray conditioner a more treatments
If I had deep enough pockets they would be mine
