The optical set up was a breeze and quite inexpensive. The improvement in sound is startling! I heard it in the first few bars of music and my wife did likewise within minutes of coming into the room. And, as the old stories go, she did not know I had changed anything. The removal of background noise I did not know I had was the stand out improvement. Every instrument was truer. Each note stood out in its own space. Each brush stroke on a cymbal was wire touching brass. I have listened to Brubeck - Time Out since I was 7 years old (65 years!). It is my go to test disc. I have so many versions its silly. But I have never heard it like this. Even from my Classic Records 45rpm Quiex 4 album set. More listening to do but as an initial reaction, call me impressed.
