That's right. Especially when playing electrically recorded 78's I find that the RIAA curve cuts the treble too much, and boosts the bass too much. When playing acoustic recordings RIAA is pretty good, since they have a limited frequency range: there isn't a lot of treble, so treble cut becomes a very effective hiss filter, and since there isn't much bass to begin with, the bass boost can't do a lot of damage. Unless of course the record has a lot of rumble.Wolfe wrote:There's nothing wrong about using RIAA for casual listening, especially if you have tone controls to tailor the sound just a bit. Indeed, the RIAA curve helps reduce a lot of surface noise w/out having to go to a lot of other folderol.
If you want to make digitsl copies of your 78's and want to achieve the best results, then, bypassing RIAA and utilizing other curves matters more.
I'm a big fan of the KAB VSP (Vintage Signal Processor) http://www.kabusa.com/frameset.htm?/
It's basically a very advanced phono preamp. You can choose between several different equaliser settings (also RIAA), it has a real time click-pop filter (all analogue, so no digital artifacts), a vertical/lateral switch, a hiss filter, etc. It's a great piece of equipment, and I really recommend it.
