thanks.
the dimensions of those speakers are the same as the B & W ones I am removing because they take up too much space. Orb Audio is a newer, very commercial company, but they appear to have a very good product.
Looking for high end quality with a small footprint. For the receiver, this means that the depth needs to be under 13 or 12" to fit in a small cabinet.
Am looking at network receivers from Denon (RCD-N7) and Cambridge Audio (sonata NP30), in addition to the NAD mentioned above.
