tube dacs vs solid state dacs


there have been a number of posts extolling the virtues of seceral brands of solid state dacs.

however, it would seem that the flexibility of tube variation, especially in the gain stage , should best the performance of most solid state dacs.

yes , it brings to mind the issue of tubes vs solid state, but i think the particular facility available to tube dac owners vs solid state dacs has not been sufficiently emphasized.

I generally prefer tubes when it comes to amps and preamps. With source-DAC/CD players I find SS vs tube far less important compared to the overall implementation. A good SS discrete output stage,no negative feedback and with a robust power supply can sound as good or better than a tube output stage. Execution seems to matter the most.
