Tube DAC ?


I posted this in analog and was told it should be here.

My system: McIntosh C 500 tube pre

                    Berning ZH270 amp x 2

                    TT , DCP and Merlin floor speakers

My question is, would a tube DAC help or hinder?

Thank you for your input.

You'll get differing opinions but since you have a tube pre amp if you like the sound you have now a tube dac will add coloration to it. I would try both one or so with tubes and without. 
Get a nice clean, crisp, transparent, neutral, musical DAC...  Have you done any tube rolling with your C500 Pre or ZH270 Amp?  You have a lot of tubed sugar going on there...  You need to demo some DACs in your system to know what sounds good to your ears/brain...  I love the sound of tubes although in my system I chose a non-tubed DAC...  Good luck in your search...
