I can tell you for a fact that Vinyl does sound better then a "Redbook" CD, but there are alot of factors involved......
1. You need a fairly good analog section (TT, Cart., phono pre-amp) and
does not come cheap.
2. You "HAVE" to have a way to make sure the LP is very clean and
that is not easy or cheap.
3. The LP it self has to be of a good quality, alot of them are not up to
standards, cheap grade (noisy) vinyl, poor manufacturing process....
4. If all your ducks are in line still alot of care needs to be taken in the
handling of the LP so it does not get scratched......
5. Making sure no vibrations get through the tone arm while said LP is
being played (use of isolation products).
So as you can see it takes alot but it is well worth the effort if you do want the best in audio re-production......as for SACD and DVDA well I have not yet had the chance to compare a SACD and an LP of the same title but hopefully in the next month I will (just purchased a SACD player), and after I do I will post a note about the effort........
CD's do have thier place though, easy to use, very durable and they do sound very good and lots of them..every where.............
Everyone have a good holiday.................
