Why do I need a phono-pre???

All depends on whether your receiver has a phono-stage in it. In the days before CDs, they all did; now most don't.

All that plus many of the cartridges today have a lower output voltage than many of the popular ones from an earlier era. I'm not sure that some of the lower output moving coil cartridges would be adequately amplified with the built-in phono stages of a mass market receiver.

Besides, audiophiles love separates! ;-)

You will need a RIAA (phono-pre as you call it) The reciver your parents used probably had one integrated. Most LPs are recorded using the RIAA standard. This means that the bass is lowered by 20db and the treble is 20db higher. The riaa (phono stage) converts this signal back to a normal signal. Highering the bass and lowering the treble. The reason for this is to make the bass rills in the LPs smaller and the treble rills larger, to avoid mecanical noize and uptimise storage.

most built-in phono pre-amps are cheap. You will get better sound out of a dedicated phono pre-amp provided: your turntable is better, you have an open input on your receiver or pre-amp. Prices start at $100 and go up. Good luck!

I've got an Acurus ACT-3, with a Rotel 2-channel and an Adcom 4-channel, so I'm pretty sure I'll need an RIAA. Thanks for all the help!!!!
