High resolution digital is dead. The best DAC's killed it.

When I used the EAR 324, it had a reverse polarity button that did improve LPs that were clearly reversed.  Stillness, second pressing by Brasil 66 greatly improved with the button pressed in.  First pressing was correct and fuller sounding even after second pressing correction.

Erik "Most multi-way speakers have 1 or more inverted drivers. A typical 2-way box speaker inverts the tweeter relative to the woofer (but not always)."

Sorry, I am being dense here.  Are you saying that the tweeter and woofer are set up to not work in tandem.  That is, when a signal is telling the woofer to play a note (extend out), the same signal would have the tweeter do the opposite? Or maybe to say it in another way, the woofer and tweeter + and - are attached opposite to the signal from each other?

Jitter, good catch! If speaker drivers are not wired in the same Polarity that would be Big Gnus. 🐂 🐂 🐂 You can hear it right away, I mean, if you can hear. Why would anyone do that intentionally? If it doesn’t make sense it’s not true. JBL did have a woofer wired out of Polarity on some models for quite a while, dunno why. There’s an easy test with a battery across the driver terminals to ensure all drivers are in the same Polarity. Highly recommended. 

Thanks for the clarification.  The only reason I mentioned it is that it would have meant that when replacing drivers I had them not correct.

I have used the battery testing method, but not with a tweeter.  Can you see anything move in or out on a soft dome tweeter to test polarity?
