. The M-DAC's CROSS output stage is a full blown Class A preamplifier sporting near zero output impedance. There is really no reason to daisy chain another preamp, just like you wouldn't consider running two separate preamps in a typical system.
This is interesting although I do remain sceptical. The CDQ was claimed not to need a separate preamp but the valve grounded grid is still in line doing a sterling job of improving dynamics, authority, making the sound stage more three-dimensional and improving musical timing.
I am considering getting it re-built with a better, more modern and quieter toroidal transformer, removing the one capacitor so that it is directly coupled throughout and having it housed in a non-ferrous box.
However, if, as you say, a separate preamp is not needed and my ears agree (entirely possible) then I will save my money.
