The best way I can describe it, especially in instrumental and classical music, with balanced during quiet parts, the quiet is more void. When the instruments start again, it's more lively coming out of that dark quiet.I thought that too. But when I tried my Pro plus directly into my Apollon NCx500 instead of via the (balanced) Topping D70 Pro DAC, I honestly couldn't hear any noise, nor really any significant difference in sound. Neither could my partner (maybe a *hint* of something made her actually slightly prefer without the DAC, could just be different filters between the two)
Calling it noise using RCA is an exaggeration for me, but if I had the choice I'll take balanced every time.
