I don’t think it is on a level playing field for a controlled comparison-- b/c upstairs where the main system is, I could not get the SP-10 to isolate, even with a heavy plinth, rubber feet and a big Ginko cloud. The SP-10 does duty in the vintage system on the ground floor, centered around Quad ’57s, using antiques, an Mc 110z preamp tuner, and a pair of old Quad IIs from the late ’50s early ’60s. Everything was gone over by the late Bill Thalmann, and top glass in everything, but still, it is a limited bandwidth, limited dynamics system, and would not make for a fair comparison, @Inna. PS: the model is the early one, before the mk ii and iii and does not benefit from the further refinements in motor and heavy platter, though it is somewhat scarce in the wild. I have owned it for more than 50 years and wanted to put it back in use, rather than buy a new table for the purposes it is used.
On the Brinkman, I couldn’t believe the difference it made favoring the tube. I’m not sure why, since it isn’t directly in the audio path, but there it was.
