Damn Rich, I just read the link provided. Pretty cool stuff. I apologize for not reading the link before. I was at work and I didn't have time to read it.
I have had time tonight and this laser pickup really sounds like it could stomp any record stylus out there for fidelity [in theory], however it reads just a small sampling of the groove. Not knowing jack about the grooves of a record, I take it that the same information is at the top of the groove as well as at the bottom of the groove? Basically, look at the picture below and you will see that the point of the groove isn't touched by the laser at all and even though this player has five lasers, all but two are utilized for alignment so the two that actually read the groove at 10 microns below the shoulder. I guess it has to be, the same information being from the shoulder to the bottom of the groove, right?
Now, another thought of mine was that if you have one side of the groove worn more than the other from the needle being out of alignment [I forget the term...VTI maybe?] and you have a record that has been played many, many times riding one side of the groove more so than the other, wouldn't [In theory again] the indentation of wear ride up to where the laser reads the groove?
Does anybody know the kinks that they are still working out? Is it reliability or tracking?
"Only the part of the beams that reach the groove are reflected to two PSD (Position Sensitive Detector) optical semiconductors. The part of the beams that fall on the land area of the record are deflected and not picked up by the PSD devices. The signals are sent to a microprocessor via analog to digital converters, then to servos to maintain the reader head position directly above the groove.
Unless I am reading this incorrectly, it is still going thru an A/D converter which kills the aspect of getting vinyl sound, you are just reading it from a vinyl source, correct?
It is my understanding that most of the beauty of analog is that is is not converted, compressed or altered in any way with the exception of the quality of the stylus and the TT . Am I incorrect?
Now, on another note....
I tried to work it out to where the record flattener would be available for Carverfest not only this year and for future Carverfests and the current owners and I feel that it would be to difficult to break up the schedule/rotation for that unit. So, I am down to three options..
1. Buy the flattener myself.
2. Have several Carver members become co-owners of the flattener.
3. Screw you guys and and become part owner of their flattener, working with the schedule that's already established.
I am open to suggestions and co-owners of this unit. I personally need this unit because I have 300 or so albums that have been sitting in storage for twenty some-odd years. At the bottom of each vertically stored album, there is a slight curve, disrupting the playback of the outermost part of the album. I have also noticed that albums that have been stored in double LP sets are also warped slightly where the album was folded together. There is no way in hell I'm gonna buy each album over again [even if I could, some aren't even available anymore], so this flattener will be a reality for me...whatever route I choose to go.
