Citation 12: what are the input capacitors for?

I have a Citation 12 here, courtesy of a friend. I’ve been looking over the design and contemplating the Pass/MF12 redo. My desire to look before I leap won out and I started checking values on the stock chassis with a DMM and just doing a visual once-over. When I flipped that chassis to look…

Is this cartridge snake oil ?

This is the famous Denon DL103 cartridge, to which they change the weak original plastic casing (one of the complaints of the users is that they do not allow a firm fit) for a solid and beautiful metal casing (anodized aluminum) and wood to choose . All of which will make you enter a musical…

I’m thinking specifically of how the BA-3 front end can also be used as the core of a preamp. Is this usually the case, at least in principle if not practicality? More generally, would it be beneficial to remove this double gain and make either the preamp or power amp input passive, to reduce the…
