At least I think I have. And I feel like an idiot.

I decided to give the Erses another shot. So I started to unscrew that elegant wire nut connection in the right-channel low-pass section to remove its stock inductor. The coil lead was connected securely enough, so was the lead to the speaker terminal, but the cap's somewhat shorter stripped lead, though also apparently connected during playback with the stock inductor, slipped out a little too quickly. And the light went on. Could I have been running a 6db/oct. first-order on the right channel bass when the Erse had been in previously? You see the implications. Chestiness, muddiness, bleed-in to the upper midrange, loss of locational precision, yada, yada.

In went the Erse, and I made sure the three-lead connection was secure. Same on the left channel. Then I put Sarah back on. Yep, the Sarah I know and love, with just a touch more low-end foundation and none of the smeary patina I'd heard before. The orchestral accompaniment sounded airier and more spacious, everything where it ought to be.

I have more listening to do with the Erses in, but sounds at this point as if they'll stay.

Guess I have get out the WBT solder, after all. My apologies to Erse, to the concept of DCR, and to everyone who I put through my previously-read nonsense.

Hell, I know better. And your post got me back on the right track. Thanks.
