Hey there Chris, I've been auditioning the DDP-1 and PS-5 as well as an Ayre Codex this weekend. Thanks for your review on the DDP-1, it's a stunning prepro and will take my digital listening to the next level. Not as impressed with the Codex.
Did you compare the DDP-1 with and without the PS-5? If so what are your thoughts? Does the PS-5 provide an improvement in sound performance of the DDP-1 over it's stock power supply? I'm on the fence and am not sure if I can hear a difference.
Please check PM thanks!
Hoping you have an interest :)
