How much better are the Classic 45 rpm vs 33 LPs?


I'm thinking about buying some of these. Some in print, some out. The out's are getting pricey. How much better do things sound in 45rpm vs 33.3? Thanks for your opinions!

there are also singles 12"/33.5rpm that have wider grooves but different carts may act in that case differently and so is on different speeds.
i have lots of 12"/45rpm and most of the time they're all excellent.
speaking of 45's check out this link to a Steve Hoffman forum,
