My problem with the Dodson 2l8 (and the reason I went in a different direction) is that if you had a 2l7 Mk II D, the upgrade offered would only get you about 30% of the way to a 218. To go to the 218 would involve selling the 217 for about $3500.00 (50% depreciation) and then forking over another $4500.00 for the 218. This is why I got rid of both the Sony SCD 777ES, and the Dodson 217, and got the Esoteric DV-50, which plays redbook CD's better than the 217, plus excellent playback of SACD's and DVD Audio discs.
