I just parted with my Spendor BC1 speakers. I auditioned the MG-10 at the dealer and again at home before I decided to buy them. Quite excellent on all counts and nearly all music (I have not played rock). The room is well damped and I play a lot of vinyl. I have tube equipment and anti-cable speaker hookup wire. There is a lot more detail and air from these units compared to the Spendors which I thought quite excellent for a long while.The midrange is close. The most important input is that even though there is a lot more detail the units are not fatiguing to listen to which when it occurs is usually a sign of peakiness in the reproduction. You should audition them in your set up.
