I went from a 2A3 amp to a 300B, and Steve at Herbie's Audio Lab told me to just send back his Hal-o's for the 2A3 and I could pay the small difference to get those for the 300B. This was after I'd been using the Hal-o's for six months.
Also, there is a seller on Audiogon called Hawthorne Stereo, in Seattle. On two occasions I purchased used equipment from them, and they gave me 100% credit when I upgraded...nearly two years later!
