I think we've had this discussion of switching PSs before on this thread, but maybe not. Anyway, at that time I also pointed out that David Berning, the designer of Berning amplification products, has been using switching power supplies at least in his (tube) amplifiers for many years, certainly more than a decade. Meantime, his products are much admired and not inexpensive. So far as I know, no reviewer or end user has ever complained about switching noise or anything of that sort. I have used (briefly) two of his ZH270 amplifiers in mono configuration to drive my Sound Lab speakers and detected no problem related to PSs. Keep in mind that DB is a brilliant fellow and an innovative engineer; not all switching power supplies are created equal. So-called linear power supplies can also be crappy if badly implemented.
Vintage DD turntables. Are we living dangerously?
I have just acquired a 32 year old JVC/Victor TT-101 DD turntable after having its lesser brother, the TT-81 for the last year.
TT-101
This is one of the great DD designs made at a time when the giant Japanese electronics companies like Technics, Denon, JVC/Victor and Pioneer could pour millions of dollars into 'flagship' models to 'enhance' their lower range models which often sold in the millions.
Because of their complexity however.......if they malfunction.....parts are 'unobtanium'....and they often cannot be repaired.
