Sony PS-J10 internal RIAA normalizer, use the internal one, or should I build my own?

I have a Sony PS-J10 turntable with internal RIAA curve normalizer. When that normalizer is on, I can connect the record player to a standard line input and it will sound - well normalized.

The problem is though, it seems it's pretty heavy on the trebles, so I use the equalizer on my mixer to tweak that. Now, would it make sense, to build my own RIAA normalizer / phono pre-amp? Or would I most probaly not gain anything and maybe I actually should stick with the internal one?

Any suggestions?

What are your plans for your turntable? Play some old records? Listen to new records? Digitize some old records?

I agree with [JAZ]. Building your own preamp is too much trouble for this experiment. And to do "right", it would be best if you test your design... And if you have the equipment and knowledge to test your own design you can probably test the preamp built-into your turntable.


You can buy a phono preamp for about $20 USD. You are not gong to get the "best" for that price, but it would give you something to compare to. (And, it might perfectly adequate... The components to build a good phono preamp are not terribly expenisve.)

The phono cartridge usually has more frequency response variation than the preamp. But I'm not sure I'd recommend upgrading the cartridge unless you wanted to upgrade the turntable too.

You can get a Test Record to test your cartridge and preamp together. But personally I wouldn't bother. I gave-up the loosing battle of trying to perfect analog sound when I got my 1st CD player! wink.gif

You mean there is too much treble? That's unusual, unless you have tracking distortion which can emphasize (and distort) "S" sounds. If you think that might be your problem, try increasing the tracking force (if your tonearm has an adjustment.... And stay within the cartridge specs, if you have specs for tracking force0.

Records vary a lot! I'd say most older records made before the late 1970's (before the disco era) were a bit on the "dull" side (not much treble). At least with pop & rock records... In general, it seems that more care went into classical & jazz recordings. Things got a better toward the end of the vinyl era, but vinyl was never as consistant as CD.

I'd say just use your your bass/treble controls or graphic equalizer if you have one, and adjust for what sounds good to you. If you digitizing old records, use audio editing software (equalizer effect) to adjust the frequency balance.
