New Vandersteen oil cooled hybrid amplifiers

Heard Vandersteen liquid cooled amplifiers over the weekend. Richard Vandersteen introduced them himself at NY Audio Show. The Amps have built in oil pumps that pump oil around a solid copper block that the transistors are bolted to. The oil is then recirculated across large external heatsinks that transfer heat out into the room. The transistors are said to stay within +- 2% of optimal operating temperature range. 6H30 tube driving solid state output. Interesting design if not overkill at the low power levels being achieved. Anyone else see or hear these amps? Thoughts or feedback appreciated.
