I'd rather (or my wife would rather) that I not get another amp, but that’s interesting about the "format wars". Selectable phono equalization would be ideal for that, though a DSP could be used on other than vinyl.
(Tho' maybe I could get a Bogen in my shed?)

I see Bogens come up on ebay, but I'm in Australia, and post would be prohibitive, any other brands caome to mind
Cheers
