WTD Leak 'Sound Stager' (or similar)
Hi guys I'm after a passive line volume device.
Basically it just has to have one line in/one line out and L&R independent gain/volume pots.
Something like the Leak 'sound stager' pictured below:

Doesn't have to be the best of the best (although quality would be nice) if it works I might build a much better spec'd one.
I basically have an incurable image 'slant' because of the shape of my room and the only way to fix it is to increase the SPL of the right speaker by a couple of db.
I have a digital parametric EQ which would work but obviously can;t use that with the vinyl!
Let me know if you have naything,
Cheers
