Dertonearm, There may actually be women who read this thread, so I would be careful. For example, your wife may have access to the internet. Nevertheless, this reminds me of the belt-drive/direct- or idler-drive controversy as well. But seriously, I found and am finding with the hybrid cascode that the sound was very affected by the choice of the tube in the top part of the cascode. Once I made that choice, the sound is further greatly affected by the value of the plate resistor (which of course has a critical effect on gain) and the amount of current through the circuit. (Primarily, I found that lower value plate Rs sounded better, less sterile, up to a point where the plate R = about 10X the Rp of the tube itself.) Also, how one sets the voltage at the grid of the top tube makes a noticeable difference. All of these elements greatly alter the presentation of the qualities you discuss, not to mention the similar choices that needed to be made with respect to the phono output stage. That's what makes this an endlessly interesting and sometimes frustrating hobby. (PS, I would never recommend doing what I have done to a brand new Atma MP1, which is a great unit bone stock. My own unit was VERY used when I bought it and needed a lot of refurbishing to begin with, so I let my imagination run a bit.)
MC Load Resistance
I am using a Denon DL-S1 Moving Coil cartridge with a VPI Scout turntable. The spec for the cartridge recommends a Load Resistance of 100 ohms, but the test data sheet included with the cartridge showed that they tested it with Load Resistance of 47K ohms. Question is, do you think it is ok to set the phono amp at 47K ohms for this cartridge?
