RCA output on a turntable?

Keep your preamp and use a phono preamp for the TT; it then plugs into your AES-3 via RCA cable. I think you need to research the Agon archives regarding analogue and what is required for a decent setup.
This topic has been widely discussed and the sound of a vinyl record is something special.

I'm not sure i'm following you... 2 preamps in series? I'll keep researching, but I havent so far found anything to really address what I'm asking...

Thanks for the input!

Not two preamps, but what you need is an outboard phono section. Your turntable output goes into the phono section, that unit's output goes into your pre-amp as a line input to your preamp. The phono section correctly equilizes the signal and boosts the gain to a line-level input. There are MANY choices these days, in all price ranges.

It can be confusing. The phono preamp is a special device used ONLY for the phono gain.
A phono cartridge has a very tiny signal. A special gain stage is REQURED to boost the signal strength, and add in the RIAA correction also REQUIRED.
that special booster is called a phono preamp.
It is NOT just another preamp in series.

Some confusion exists due to the fact all preamps used to contain this phono stage. But with the advent of digital, most pramps dropped the phono stage from their design.

So if the op wants to add a turntable he MUST add a phono stage. He can either buy one of the few turntables with a phonostage built into the turntable.. or buy any turntable and a separate phono stage. no way to get around having that phono stage built in or feestanding, it is totally required.
