I noticed that you have a pair of Cain and Cain speakers, 001 and 002. Are you a friend of the people that built them? I believe they are in Walla Walla, correct me if I am wrong. I built a pair of "Voigt Pipe" speakers 10 or so years ago and used a pair of Audax, Polydax speakers and a pair of soft dome tweeters using a crossover from a pair of large advents. The speaker were just made with mdf plywood as I was thinking of using them in my home workshop.
I was stunned at how good they sounded. They sound better than the pair of Rega NAOS speakers I use in my main system upstairs but there is the WAF (wife acceptance factor).
She agrees they are the best sounding speakers in the house, but mdf doesn't fit with the decor!
Here is a picture of my main system. I built the two monoblock 300b amps with some direction from Paul Birkeland. I would love to see your Cain and Cain system.
Also, the Rega NAOS speakers are a folded version of the Voigt pipe!
