The Teddy Pardo XPS really delivers on the nDAC, in my experience, especially for the price. The Pardo Burndy is good but I'm reading Naim's is better but expensive.
I have both Naim's and Teddy Pardo's 4 and 5 pin SNAIC's. The TP's are more dynamic! but the Naim's are more natural and musical - more Naim like.
The right power cable can make the Pardo units better.
Last month I installed Synergistic Research Orange fuses in the TeddyCap SE and the Supernait 3.
