Old vs. New Dacs.

What's considered high in the signal to noise ratio department of newer dacs(62db)? Does this number matter if the dac is SS or tube?
You can scan the digital processor measurements in the Stereophile archives to get an idea of the range of SNR. It seems to me the impact would apply equally to both SS and tube.

Would someone comment on the impact of running a signal with a dynamic range of 96dB through an analog section with an SNR of say 80dB?
personally i don't get wrapped up into specs like this. what sounds the best to you? i have purchased expensive older dacs recently over much cheaper newer dacs because i like the sound better. or example, the older classe, audio research, and mark levinson dacs are still in demand.
I agree, older DAC may have the lower spec but it sound different to some of the latest up sample dac... Not better or worst just different you need to hear it and compare it.
