Nice job, quality gear as it's obvious its not your first attempt, matching is so important. This process can take a long time and can be expensive. Has your bar changed as you have gotten older, and where is it now?
I detect that you might be Canadian, a previous comment makes a hint in that direction and some of your equipment is made in Canada i.e. EMM, Absolare and IsoAcoustics. If so, is the connection relevant?
I too own Tannoys, Churchills No.'s 48 , fully balanced OTL's Atma-Sphere's amp's and pre's. dcS Debussy, SME Model10 , improved V arm and a Koetsu rosewood platinum cartridge. The interconnects and speaker cables are Cardas with other cords of Furtech and Purist.
You are lucky in a sense to be where you are in 30 years; it's taken me 60. In my case the people, listening experiences have been fascinating, each a story unto themselves.
In my old age I seem to be gravitating to "low level listening". In a quest for a lower noise floor, micro-acoustics seem to be more and more important, so off I go in the direction of isolation, various types of conditioning etc. I'm actually amazed at the difference in cleaning up the lines and stopping cross contamination. The sound signature of my system doesn't change but the low level information has surely changed.
Enough said. If the above peaks your interest, I'd be happy to discuss. R. J.
