Hi Romy:See below an interesting approach. It probably violates some of your axioms but it does seem rather promising methink, without having heard it. Maybe Jessie Dazzle knows about these and could give us the lowdown as they seem rather close to ...

Hi Jessie, Thanks for reply. I am Mac based and am looking at the following idea for sending music from my computer to my audio system. The guy that builds it says that the sound is much better than he gets out of CD-playback, who knows. ...

Interesting, thanks, Jessie. I am not familiar with this one if I would not look under normal circumstances for London Symphony from 50-60s. As I understand 1958-59 it was after Krips lead LSO and moved to US, interesting… Another interning fact the ...

Thanks, Jessie!I also miss Tesla, and I agree, there should be more guys like this.May you and the other hyper-inquisitives enjoy Mr. Sheldrake as much as I do! (yeah, the "dogs" are good, but keep searching until you find the "speed of communication...

Hi jessie, thanks for tip. I will clean them myself, though I was planning on having the magnet recharged at same time, and I can't do that myself... The 3in1 oil idea is too scary for me, let me know how it works for you 8-) ...

Jessie, are you saying that the RAID system is "quiet" with respect to regular old audible noise from the unit, itself? How is it with respect to the filthy switching backwash on the AC line and EMI/RFI broadcasting?Best regards,Paul S...

Thank you all for your ideas and suggestions on RTA.Romy -- you are correct, measurements always need to be made in context of sonic experience and more importantly musical intention. For me, though, to begin the process, I need to unlearn much of wh...
