Is it a sonical advantage to replace my BZLS with a passiv preamp when using the ZEN V4?
I think with ZEN V4 it could be done more easily compared to the original ZEN version.
I have an active crossover (Thel, 24 db/oct) with op-amps. Is it necessary to use the BZLS? I think when using the BZLS there are more parts in the circuitry

It's very easy to check it out. Just disconnect the active circuitry in your BOZ and use pot alone. Your ears should tell you what's better.
I tried to connect the output of my DAC directly to the original Zen, without even a pot, but the amp sounded better with a preamp. But it was Zen without a buffer.

Nelson Pass said:Your source will have to have quite a bit of gain to
drive ZV4 with a passive. Quite a few CD players, like
the Wadia and Theta products do.
My Sony with Passlabs D1 I/V converter also do.
Passive with V4 Zen
I am building one now with the passive built in the box. An integrated V4!. But I am using a BUF634 in between the 25OK pots and the 49K series input resistors to put some drive into the amp.
The overall system gain will work in my system due to the efficicency of the speakers. With normal efficiency speakers more voltage into the V4 may be required than the CD standard.
What I am looking for now is some 1/4" shaft extenders to keep the wiring at the rear of the V4. Does anyone know a source on the net for these?
