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

Some of the 45's are amazing--Reiner's Scheherezade, Kondrashin's Capriccio Italien and Espagnole, Reiner's Zarathustra, Gibson's Gounod etc. record, maybe the Reiner Respighi, although it's a bit bright, the Mercury Firebird, Chabrier, Prokofiev--others are a bit better than the 33's, but not much. You might be interested to know that the Speakers Corner website now announces a new series of Decca 45 reissues, starting with La Fille Mal Gardee in July. Don't run to the phone--neither Acoustic Sounds nor any of the other specialty dealers know anything about them yet.

thanks everyone !!

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,
