Back in 2008 I had a vintage stacked double New Large Advent system with a Harman Kardon Citation 11 preamp and two Phase Linear 400 power amps (one 200 watt channel for each speaker). The New Large Advent had a different tweeter/woofer configuration as well as different tweeters and woofers. With Pete's BSC circuit and staying in the sweet spot they were impeccable. But it was all a bit massive and I got rid of it all for a modern system of Emotiva gear and Magnestand modified Magnepan MMG speakers.
