@jjss49 Thanks! Much of the enjoyment has to do with the B&W 685s which to my ears sound wonderful under the open air environment. I believe the balance between bass and treble is improved. The 100wpc provided by the 701 delivers the volume required with volume control never reaching 12 o'clock. I live in the country so can play it pretty loud. I have not measured the dB level at the listening position however.
Not sure about that adaptor. I put in a dedicated line run off a sub panel for the outside system.
