PBN Audio is the brainchild of Peter Bichel Noerbaek and its line of equipment runs end-to-end. On exhibit were the Liberty Innerchoic Loudspeakers ($15,000/pair) that use 48 layers of MDF in an “eggcrate” construction on the interior walls to “absorb unwanted reflective sound waves”, the Olympia EB-SA1 ($15,000/each), named in honor of Erno Borbely, can be run as a stereo amp or monoblocks with the flip of a switch, the Olympia PX Phono stage ($20,000), Olympia LX line stage ($20,000) and the Groovemaster turntable ($10,000) sporting a 12" SME tonearm. Speaker cable and interconnects were the XLO Signature 3 and a 75ohm BNC cable was used between the line-stage and amplifier.
While there was no room treatment in sight and the Liberty Innerchoic loudspeakers were not exactly bass shy, there were no room issues that plagued some other exhibitors. My notes on the sound read"groovy."
