@tomthiel -
Thank you - we'll try that. I grew up a Linnie, so prefer to have a single pair of speakers in a room. The prior owner is sending me the pins so I can experiment with and without them. Just a brief listen was positive - airy and relaxed sounding (in the best sense of relaxed).
I'd try one of the biwire sets I have, but they are bananas all the way around.
