New speakers arrived and am listening the first side of DSOTM (as I had just played on the old speakers) and the first thing that is obvious is the increased sound stage depth and improvement in the smoothness between the drivers. The mid-to-low bass is faster/tauter, as well. First listen is an improvement on classic rock. Many genres to go (and, not fully broken-in). Not too unexpected as one moves up the food-chain in $$.
Optimizing placement, etc., still weeks away as they break-in.
Extremely well packed (with white gloves - don't they all these days) with two cloth bags per speaker. The finish is stunning. As much as I think the fit & finish of the Canton Refs is tops, the Duetto is a cut above.
