Thanks Arthur I thought the cool blue glow looked familiar!
In room 522 with Purity Audio, we ran a pair of Cherry digital amps on Friday. They appeared to be "raw" with no prior break-in, so we switched to a pair of McAllister OTL tube mono blocks. Unfortunately, the amps had suffered shipping damage, as there was distortion in the right amp, and a different type of buzzing sound coming from the tweeter on the other amp. Changing out the amps proved that the McAllisters had been damaged in shipping, as the sound with the KR Audio SXi Mk2 integrated amp we used late Saturday night was revelatory - no buzz, no distortion, just clean, pure sound with an incredible 3-D sound stage. The KR rep wouldn't let us use the amp on Sunday, as he had it in another room, but I've ordered the KR amp for use at CES this year. We will take Bill Baker's Purity Audio Ultra GT preamp, as it is the very best preamp I have ever tested (and it ought to be at $29,000 MSRP). During the audition of the KR Audio SXi Mk2 integrated map using the Kronzilla tubes, everyone in the room commented on the fact that the sound of these components were elevated to a lever higher than any other room we had heard at RMAF. Dog gone shame we couldn't have used this amp for the entire show!The Jolida/Von Schweikert room using the VR-5 Anniversary Mk2 won "The Oasis Award" by Positive Feedback for excellence in sound (it's kinda like a "best sound of show award" according to David Robinson, Editor of PF).We all had a great time and sold lots of speakers, so we thought all of our three rooms did a great job for us.
