Is it possible to use the BA-3 front-end as a pre-amp? I think I read it can, but can't find the reference.
Has anyone used it as pre-amp and do you have any impressions on the sound? I'm currently using a BOZ-J and would like a bit more drive for a bi-amp setup running the L'amp CCS and a F5.
Thanks,
Vince
Note:
If using Fairchild mosfets, use 1K variable resistors for P1 and P2.
Volume control- 20K to 50K

Here is a link to someone who built one as a preamp > http://www.diyaudio.com/forums/pass-labs/196857-between-f4-f5-3.html The details are vague at best !
ZM said that.
Look for post1029 and post 1031here:

It was the intention of the people starting with the Burning Amp series that the Burning Anp should be used in a modular way means mixing allowed of frontends and outputstages, wasn't it Mark himself mentioning this...
I look for the sources...
I found it....

scroll down the page , read my longish comment , where I ( as usually

... would like a bit more drive for a bi-amp setup
I suppose you would want to have seperate attenuators for each channel/amp
juma have shown a jboz like input with B1 like output
might work for biamping
or maybe consider active xo

I'm using a 2-way active crossover (MOX II).

I find the JBOZ a bit light. I really like it, but it needs a bit more push.
Sounds to me that the BA-3 pre has that extra push.
I also have a B1 in the house. It's connected to another system.
it isn't changed , "except" introducing bridge resistor ( each halve serving as virtual gnd to other one)
be sure to have bleeder resistors after output caps ; as drawn , FE is part of amp itself , so they aren't necessary
when stage used/packed standalone , they must be implemented

After reading (links ZM posted) I have a question: As ZM told for the FE application you need bigger voltage swing, so like ~30V rail, but people are suggest to power BA-3 from the same PSU they use for F4. Will a separate PSU which give ~30V rail be suitable for either applications of BA-3: FE(for F4) and preamp other FW amp?
