basic passive preamp

hocheye

Sent you a PM re the  Reference Line preeminance one, I can always have another passive to do demo A/B's against my unit.

Cheers George

Yes the McCormack Micro line drive is a great potentiometer based passive, with an active stage that can be switched in as well, if your source has low output voltage, <1v. 
Trouble is the active stage is just a  Analog Devices AD712 dual-op-amp chip, not the best of audio opamps, that would be better replaced for dual OPA627's per channel on Browndog adapter boards.
And I think it's only available s/h, long discontinued now.

 George I didn't understand your post re what are on ebay for under $100. And how does the sound quality of the Schitt compare to the others 

Hi, when you said in your first post affordable. I thought cheap but good. The Schiits volume control inside is every bit as good as other potentiometer based passives being presented here that are far more expensive. That’s what makes them a great buy, with a return policy.

I also manufacture the LDR based passive the Lightspeed Attenuator which is maybe too expensive for you, and only one input. Second from the top in this link.

And this is just one of the ebay line level rca switch box.

You want 10kohm log cheap and good quality, there are many on ebay under $100?
The pick for me though is the 10kohm log Schiit Sys. $49 and if you don’t like it you can send it back.
And if you need more inputs there are many rca input switch boxes on ebay cheap.

Cheers George
