My first entry to streaming audio was with a Bluesound Powernode 2 about 2 years ago. I was very impressed, both with the sound quality and user interface. It was a big step up from my old Pioneer A400/CD player combo. In fact, the whole experience rekindled my interest in ‘hifi’ and since then I have become a Roon convert (Rock on a NUC 7i3), started feeding the Powernode with a Chord Mojo, built my own set of single driver transmission line speakers, and most recently added an Allo Usbridge. Each of these steps have provided worthwhile improvements in sound quality.
Since I started using Roon and the Mojo I have simply been using the powernode as an amplifier via its 3.5 mm jack analogue input and I have started to wonder whether the next upgrade would be to move to a better quality amp. I have been impressed with the D class amp in the powernode (Hypex based I understand), so am drawn to a quality D class to replace it. Initial thoughts were the Allo Volt+ D which has quite a few fans on various forums, but then I stumbled across the Audiophonics pa-s125nc which seems to be a largely unmodified implementation of the Hypex NC122mp for a little more money than the Volt+ D. The Hypex NC amps seem to attract a lot of positive reviews for their transparency which is what I am after.
I intend to feed the Mojo signal direct into the amp without a preamp, which I understand should work OK, and then use the Mojo volume controls, or Roon DSP volume as a remote option.
I guess my question is whether anyone has experience of either of these amps, or have alternatives they might suggest.
