I just bought a pair of these from a local audiophile and as much as I would love to keep both of them I can only justify keeping one from a financial standpoint so am putting both of them up for sale and will keep whichever one does not sell first. :-(The NEWER unit follows the design of the KAV-250A/3. Here is the response from Krell technical support on this. "The earlier version KAV-250a’s had audio inputs and outputs for bi-amp purposes. They also had a bridging switch as well as mono connection info on the rear panel. When the KAV-250a/3 came out, although the amp channel was still the same as in the original KAV-250a, we had made changes as to how they were bridged (using internal ribbon cable jumpers) as well as to the rear panels, and we eliminated the audio outputs at that time." I have rated the cosmetics as a "7 to 8" per the USAudioMart condition scale which is my mind is still VERY GOOD cosmetic condition. One of the edges on the front face has a slight scuff. I do NOT have the ORIGINAL shipping box however am very experienced and packing electronics for safe shipment.. Included is the AMP and the power cord. $900 shipped to CONUS
