Banquo363,
Thanks very much. Yes, I've placed the power supply on the Symposium precision couplers and sat that on the Symposium svelte platform - which sits on the birch shelf. These viscoelastic platforms still work effectively under electronics (such as power supplies and amplifiers - also spectacular between stands and speakers).
On the Gould, I much prefer the 1981 rendition (1982 recording). His introspection and maturity just seem more appealing and engaging. I also think the recording quality is better and his habitual background vocals just seem to add to the 1982 recording in ways that his 1955 cannot.Maybe that's all just a reflection of my own aging perspectives finding accord with his.
