Rushton, My turntable is no where near the status of your Walker however the 45 rpm Ravel, "Rapsodie Espagnole" in my system is every bit as dynamic and detailed as the Prokofiev,Scythian Suite 45 rpm of which I have. I would not be surprised if you found it the equal of Stravinsky/Firebird 45 rpm. Unfortunately I dallied too long in purchasing the 45rpm version of Firebird. If it shows up somewhere the price will no doubt be out of my reach. However I do have the 200g version and am happy to at least have this format.
I have just finish paying dearly for a couple of records that nearly doubled in price because there were only a few copies left in stock.
Today I just heeded some earlier advice to obtain Starker's Cello Suites/Mercury Speakers Corner before it goes out of print. Acoutic Sounds has it back ordered and some of the other outlets are out of stock. Fortunately Music Direct had it at list price so I did not delay any longer and purchased it today.
In a few years I think we will not regret the financial sacrifice of obtaining these remarkable reissues. I remember years ago when Sid Marks of the Absolute sound did his column on Mercury Living Presence and RCA Shaded Dogs how difficult it was to find clean first issue copies. And if you did find them the prices at least for me was prohibitive. To have them reissed with original cover art and superior vinyl is an analog lovers dream.
