Capitol Audiofest 2018
« on: 11 Nov 2018, 08:34 pm »
This was our first Capfest. We really enjoyed the venue and all the showgoers.

We demonstrated the Spatial M3 Triode Master speakers with Linear Tube Audio's Ultralinear 22W amp and their new preamp and AntiCables. David Berning was on hand to greet listeners and discuss his unique technology. AV Showrooms did a video with Berning, Mark Schneider of LTA and myself. It should live on their site around the first of December.

The M3 TM's having a 12 ohm impedance are very compatible with an OTL amplifier, or any tube amp. I guess But there is something special about an OTL amp. and an impedance of 12-16 ohm; a synergistic combination.

Actually, because the Berning ZOTL design isn't a "regular" OTL amplifier, the output impedance of his amps is very low. Generally, I believe the models without feedback adjustment are under 2 ohms of output impedance.  ZOTLs can be used with a much wider range of speakers than traditional OTLs.

AV Showrooms just released this video from the Capitol Audiofest. David Berning explains the ZOTL circuit :)
