While it's true that modern equipment allows you to tweak or enhance playback sound quality to get the most out of old format records, I've found that certain acoustic gramophones make 78s sound very good to excellent, depending on how carefully they have been restored and when the record was made. For instance, the average (pre-1925) acoustically recorded records may sound muffled and constricted on an average budget to mid-priced modern record player, but on a carefully restored gramophone (talking machine) equipped with a large outside horn, they will deliver a tremendous presence.
Along this line, unless careful equalization is done, the most prominent sound from an acoustic recording when played on a modern record player will be surface noise--even when using the correct 78 rpm stylus. And of course, many if not most acoustic era 78s were recorded at speeds higher or lower than 78 rpm, so the ability to adjust the the turntable speed--a feature of virtually all acoustic gramophones--is a big help.
I've also found that, for early electrically recorded 78s--1926-circa 1930--the mid-size to larger exponential horn gramophones deliver a more natural sounding performance--dampening, to a certain extent, the exaggerated bass inherent to the recording process, while highlighting the treble and mid-range and putting the surface noise behind the music. (I'm sure the owners of carefully restored Ginn/EMG gramophones could probably attest.)
Personally, I also like them because, unless equipped with an electric motor, they are totally "green." Another advantage is the fact that unlike more contemporary sound systems, many, if not most, can still be repaired. It's probably a thousand times easier to locate a replacement mainspring for my circa 1907 Victor V than to find a replacement CD player or other parts for my Magnavox AZ9435--which by the way DOES need a replacement CD player
