Any benefit or harm in using a ε22 for β22?

Thread Starter 
I had been planning on using the ε22 back board for the β22 I am building, but I am reconsidering. The reason I would not is mainly for style, but also I had been concerned that the sound quality would be worse with the ε22 back board. The opposite also concerns me, that the quality would be better using the ε22.

Relevant information:
I am planning on using having the PSU housed separately, I am planning on using a gold point volume attenuator, and quality wiring.

So... from a sound quality stand point, would one way be better than the other?

(either way it will be a three channel β22)

the backplane makes it mostly foolproof to route the wires away from 'trouble areas'.

I found that if you get the wiring wrong, you get lots of hum, sometimes even noise. took me at least 3 tries before I got my b22 'clean' on my own.

I recommend using the backplane if you have it. it cannot hurt. I do believe its a 'win only' with no downside other than cost and slight increase in footprint size.


if you do want 3ch, the backplane is VERY recommended. not needed but a nice extra 10% touch, imho.



it really cleans things up. you'd be nuts not to use it if you already have one there!

Makes wiring SUPER clean, just finished one on mine. Also, your signal wires are sent with a huge ground plane surrounding it, which is nice, especially after the pot where it's a Low-Z signal that picks up noise very easily.

Of course some "cable audiophiles", such as myself, choose to run output signal wires direct.

What are the quick disconnect parts for the power and output wires? Looks like something similar to the old disk drive power cables.

Yep pretty much is, those are molex connectors.

They are Molex KK .156 connectors. See ε22 website.
