I will absolutely second the Topping E70 Velvet. If this isn't the most underrated DAC in the sub 1K price range, I don't know what is. Helomech is spot on. Save 1K and grab the E70 V....It also has balanced connections...
Upgrading to a stand alone DAC
I have the upgrade bug..lol. I am considering purchasing a stand alone DAC as 60% of my listening is thru my CD player (NAD C568). This was purchased new 3 years ago for $799.00. My budget would be $1500. Rest of system is the Marantz Ruby KI integrated amp and the Reference 3A de capo speakers. Would I hear a significant difference at this price point?
