Query: Poor sound quality - get a wire

The unit is certainly convenient to use, and pairing is rather straighforward. Range is about 30 ft in my (not very exhaustive) test. BUT: The big issue is sound quality! It brings you back to the time of tapes (muffled sound, missing highs, loss of airiness and vigor) and scratched vinyl records (hiss, and most annoyingly, regular pronounced cracks and pops that sound like bad scratches on the record).A direct A/B comparison of the source CDs (Classical) and 320kbps mp3 rips made from them shows the expected noticeable slight degradation when used with a cable; but when played through this unit, it leads to what I consider unacceptable loss of fidelity, clarity and presence. Why even bother about the digital age when this sounds like a low-to-midrange 60s and 70s setup?
