Customer Reviews
I ended up building three of the kits, one as a stereo version, using RCA's with unity gain, so it could be used inline from a preamp to an amplifier. The other two kits, I built a Balanced version, one kit for each channel, once again with unity gain so it could be used inline from my Balance BA2018 preamp to my ALEPH J amplifier. All of these projects were built using parts and enclosures from the DIY audiostore.
Very useful item, great fun.
Really softens thing up thanks. Wouldn't be without one.
I was looking to experiment and saw these boards and decided to build a couple of them.
They are very easy to build and provide an interesting sound (fuller sound).
I wound up building them for unity gain so I could put them in line with my
existing system, but they would make a nice building block for a simple preamp.
