Submissive substitute

[Natural Sound]

Well I guess I dragged my feet too long. I've been wanting a passive-pre for my Paramour II 45's for a while now. I like to keep the audio path as simple as possible. I recently came across some discretionary funding and was ready to jump on a submissive. Only to find out that it has been discontinued.

I've heard good things about khozmo.com's products in the past. Their pricing also fits well within my budget. If I decided to go this route what would be a good impedance match for me? I mainly use a Bottlehead DAC during my listening sessions so a solid 2v at the input will be available.

10k, 20k, 50k, 100k and 200k seem to be the options.

Since most bottlehead kits employ a 100k potentiometer is it safe to assume that a 100k passive-pre will provide acceptable performance? Or should I take my que from the Submissive specs, "20K ohms at the lowest end of the range to to 40K ohms at the highest end." for something more acceptable?

What do you think your cabling will look like with this setup?  If you need more than a couple of feet between the passive and the Paramours, then I'd lean more toward the 10K or 20K selection.  If you plan to add a Reduction or Eros as a second source, then the 50K unit will make more sense.

The 100K and 200K controls are not suitable for use in a passive preamp.

Thanks Paul. I hadn't thought about adding a phono pre but its a solid possibility. (I'm still using a c4s seduction but an upgrade to an Eros may be in the cards). Cabling will be as short as possible. 2 feet or less is likely.

It sounds like the 50K control is a good idea.  When I have built similar passive preamps in the past, I have built the output cabling into the chassis so that it's harder to forget that they need to be short! (Also remember that if you want to use a powered subwoofer, use the speaker level inputs)

Send me a PM, I can help you out.
