Artcurus-- I remain a big fan of the 78-rpm format, even after parting with my collection. The large grooves and 78 speed allowed for a big, loud sound. Of course, those attributes were accompanied by a fair amount of inherent surface noise and the inevitable scratches, pops and clicks of repeated plays...but I still have a nostalgic fondness for those brittle, old discs.
I love the music from that era as well, and there some really fantastic classical recordings along with all the great pop, jazz, and easy listening. I even had a "Learn French" set, which was fun.
Unfortunately, I was moving frequently at the time and tired of dealing with boxing and schlepping them from one apartment to the next, so I gave a bunch away and took the remainder to an antique shop, figuring they'd find loving homes.
On the upside, I have many of those great songs thanks to iTunes. They sound so different without all the surface noise! The most difficult album to replace was eventually found as a Russian import on CD: Rachmaninoff's 2nd Symphony in e-minor by the Minneapolis Orchestra under the direction of Dmitri Mitropoulos. That version remains my favorite to this day.
Anyway, enjoy your new hobby...and invest in some good, strong shelving, LOL.
