Jim...very nice write-up. So a quick question that confused me. The Sonographes' (both SC25 and SA250) are from the '90s but you mention that the sound "straight out of the box" was favorable but guarded. Are these new units that have never been used or do you mean since they have not been used for a while they require break-in which clearly has occurred over the past couple of days?
Congrats on the new bedroom set-up
