I have a specific reason to keep both players. If you are into auditioning different cables having a second CD player as a control is a great way to reduce the effect of expectation bias. You can get a good sense of how the two players compare in sound and then when you swap the cables on one of the players you can hear if the sound materially changed. You can do this again and again over a period of weeks and really hear if there is much of a difference. IMO this is a much better way to judge cables (or other CD player tweaks) than long term listening on one player.
I never did get an Oppo so I have 4 CD players, 3 DACs, and one transport so that I can play CD, SACD, HDCD, and DVD Audio. That's more than I need but I sort of collect and keep the ones I like. I almost pulled the trigger on the Wright modified 103 a couple times and I’m pissed that I didn’t.
