VPI had the chance years ago. Harry and the owner/designer of Phoenix Engineering Bill Carlin were in discussions about working together, but it blew up. Carlin is not the diplomatic type, and said some things Harry took offense to. That was the end of their proposed collaboration.
The original Phoenix products are long out of production (I got the last 15 watt Eagle), but Carlin developed the current versions that SOTA are making and marketing. SOTA has worked with many VPI owners, advising them on how to install a SOTA motor into the stock VPI motor pods. That enables the current Phoenix products to be used with VPI tables, with excellent results. Audiogoner @slaw has done the install on his VPI, and is very satisfied.
