And you really shouldn't be using it if your amp has differential outputs anyways.
Not sure I understand what you are saying
And you really shouldn't be using it if your amp has differential outputs anyways.
If you're tying the negatives together of a differential amp, you're basically summing them. So now you don't even have a proper difference across the left and right channel. Basically a stupid amount of crosstalk... practically halfway to mono-town.
In the case of ground-but-not-quite negatives (such as with class D, but other topogies too maybe), you're probably going to create a ton of noise, maybe some good 'ol fashioned DC offset, etc.
Interesting. I had emailed Woo a while ago and got a reply saying that a balanced amp was fine with the WEE.
Hi and thanks. i use separate amps for speakers and headphones now (two outs from preamp) but this would give me another option. one more question if i may. one of the reviews i read said that the wee would not work with speaker amps that use a balanced output such as some of the pass labs? I did not remember seeing that in the manual but i looked quickly. not an issue for my tube amp but i also have a a blue circle hybrid. Is this an issue i need to consider? Blue Circle description is
All Blue Circle amplifiers* employ true balanced output technology. This means both the positive and negative binding posts supply active signal to the speaker voice coils. The advantage This results in the amplifier applying more control over the speaker cone motion than conventional designs.
The '200 series amplifiers are the first models to take advantage of the latest design refinements to our balanced output technology. Since the negative binding posts are in fact not grounds as in most other amplifier designs we have included independent chassis /earth grounds on the rear panels of the 200 series amplifiers to accommodate installations that may require the application of a true ground.*
thanks. i am pretty sure i want to order a wee but thought i should ask about this
gary
A bridged/balanced spk amp can be used for WEE.
Thanks,
Jack

If you take the positive but tie the negative to ground it should work since you are not using the negative half of the differential amp.
I got this response from him last year...

Assuming that there's no DC offset relative to ground (not likely... but you never know sometimes).
