I had read the advance acoustic receiver. Is even more expensive. Who does what he should do, sounds neat, but much worse than a cable. So back. Then I found this 4G with digital out. I have a very good converter. Whether on PC or Tablet: punchier, audiophile sound. Exactly what I'm looking. The analog output I've never tried. I believe that in these small boxes the analog stage simply can suck. Super sub, buy recommendation. Oh, connection and function is also perfectly ... :-)
