Air Audio Services AC-2K Balanced Mains Transformer.
Reviewed by Paul Rigby for The Audiophile Man, May 2020
Conclusion.
What I liked about the AC-2K was that, firstly, it improved the entire frequency spectrum with one flick of the mains switch. Everything was enhanced, from top to bottom. Everything. There were no trade offs here, only positives.
Secondly, the inclusion of the AC-2K was tantamount to a major component upgrade because, well, that’s exactly what it is. It’s feeding the entire hi-fi system with low noise, cleaned-up power.
Grab yourself an AC-2K and, in my book, that will be money well spent.
