Does anyone play 78 Rpm records?

I collect rare Jazz and Blues 78's from the 1920's through early 50's, and I want to get the best possible sound from my records. The problem I am running into is that most "audiophile" dealers have no idea about 78's and only know vinyl which is very different. I purchased from KAB their modified Technics turntable that plays 78's and has a variable speed (which is essential for me because most 78's were not recorded at 78 rpms)and their solid state phone preamp that has all the different essential pre-RIAA equalization curves to play my records. The area I need help with is Speakers and amplification. I need something that will add color and warmth to these old discs, so I am leaning toward tubes. But would like advice from others who are serious about 78's. Also is it worth looking into vintage speakers and amps that were made in the 50's when 78 rpm records were played?
Thanks
