Hi Mark,
I purchased almost everything from Carl (which may no longer be an option), including new Circe alnico woofers and tweeters, Carl's internal wiring, and Carl's outboard crossovers that used upgraded capacitors from what was in the Circe. Other upgrades included Cardas binding posts, dynamat inside the boxes, and Sound Anchor cradle bases on spikes. I also refinished the cabinets. A lot of work, some fun, and a valuable lesson in determining early on what works well for the type of music you are going to listen to, before spending a lot of money. Instead of going the route I did, you would be better off buying used Vipers.
Sorry Jmlab926, not meaning to redirect your thread, but I believe the concensus is that you need tube amps to achieve the sound the designer intended for these speakers, and I would say at least 100 wpc. Maybe the Herron amps Harmonia uses are an exception, since she seems to like them. However, IMO, if you cannot use tube amps I personally would try other speakers.
