NAD PP2 Phono Preamp Upgrade

Would be surprised if the Kenwood didn't totally trash the NAD.

The PP2's design is not very inspiring ...

Yup, I'm afraid you're quite right... Then we have to add the WAF, and then the Kenwood is the big looser...

The problem is that as I'm using a passive pre from Dynamic Precision, I have to "loop" the phono-signal through the Kenwood to get enough gain, and then it is two pre-amps, and two volume-controls in my setup.

I have about a thousand different releases on vinyl, and it would be a pitty not to play them now and then... Of course I ought to buy a new, and really high-end RIAA-stage. This will be my next aim I guess. But first of all I must find a RIAA which gives me at least 68-70db gain, and that's not to easy, I'm afraid...

The RIAA in the Kenwood is really good, but I'd rather get away with only one pre-amp. Actually the L-1000C is a pretty good pre-amp. I've removed lots of unnessecary caps, bypassed and changed other for better qality, as well as replaced a lot of opamps (16-17 pieces...) with units from BB. Not to forget; I've wuzzed around in the PSU as well. All in all this made the Kenwood play very well in my fully balanced (XLR) setup. The Kenwood is as you may/may not know, a fully balanced unit. The only preamp I've tested better, is my Dynamic Precision BPC 7.3. With that said, I must underline that there's lots of units out there, which I have not testet!

Here's a rough diagram for the PP2 in MC mode:

I recently got a PP2 second hand without a power supply. I picked up a 24v power supply from radio shack, which causes the power light to come on, but the audio output is just humming.

The audio input is not able to be heard at all, it sounds exactly the same if the turntable isn't even hooked up.

Any ideas what the problem could be? Does this sound like a power supply issue, or is the PP2 busted?

Thanks!

Sure you got the right kind of supply for the PP2? Is your 24V supply AC, DC or regulated DC output, and what does the PP2 require?

You have to join in order to access the database and libraries there. Takes about 5 minutes to do so, and is IMHO well worth it.

Ah, you're right. I didn't even check that. The adapter provides AC and the PP2 requires DC. Feel like an idiot now!
