Using the Zen Blue which would give me the best sound Coaxial to amp or RCA to amp I mean getting the most of the Dac. Thanks
Yep, trying both is the only option.As Al says, surely you just try both? I have no idea which DAC would be better - I use the Zen Blue too and my CD's DAC is very definitely better, so that's what I use.
Luckily I have an abundance of cables. Comes with all the upgrades and they are all gathering dust. I need to stop reading cable reviews. All I buy now are the Van damme cables they are as good as any.If you already have coax and RCA cables to give the comparison a bash, why not do so? If you don't (and would therefore need to 'buy to try'), maybe just go with what cable you've already got?
Those 'in the know' generalise that BB DACs have a more musical sound, compared to the more analytical ESS Sabre sound.
