Michael, I should have read the thread more carefully, as someone already made a comment about the compromises of a all in one preamplification+digital source, as the Wadia provides.
What do you think about the DNA-2? Are you happy with its unmodded performance? It is a bear of an amp, and I wonder if you have any qualms or noticed any shortcomings with it. I myself have a DNA-225 that is sitting on my rack.
After looking at your system, it makes me wonder whether my system is pulling into too many directions and have too many sources that I would like to play with, such as Phono, Tuner as well as Digital. In all honest reality, how many of these sources do I use extensively? Some I use more than others.
Therefore, your system had got me really thinking about sonic and space priorities.
Have you tried passive attenuation with a source?
I have a pair of EVS Ultra Attenuators and I am thinking about experimenting with what I have. Once I did something like that, pairing my Op Chip monos, the EVS, a DAC and the Epos ES11s...Sure the sound was clear, but it felt a little too bleached out, presentation wise. The instruments and the vocals seem to be distinct and yet, lumped together...almost clinical.
But, with this sort of experimentation, I think one needs just the right set of pieces, be it cabling, source, amplification and loudspeaker. More than equipment matching, it is more like alchemy.
Cheers for all the good music that you must listen in your system.
