I heard one many years ago in a reviewer’s system. The entire system was about $400k and fantastic. Of course I couldn’t identify how much the player attributed to the sound quality. It was a unique item back then, but today at least as far as servers go, buffered or “memory” playback is common.
And of course use of CD’s is a lifestyle choice. Personally I haven’t played a CD in over a decade, and prefer my music on a server I can control from my phone, and most of the digital music I play is hires. If I’m going to spin a disc it will be vinyl.
Please post back and let us know how the memory player works for you.
