I hope someone can help me with a question. I have three Sony SACD players that I have been playing with, and I was thinking about a clock modification to one of them but I don't know the clock frequency in use. The players I have are as follows: SCD-XE670, SCD-CE775, and SCD-C333ES. I have a spare NET Audio 16.9344MHz Clock Upgrade hanging around that I would like to have installed into one of these players if it is compatible, but I am having trouble finding information. Any help would be truly appreciated. Cheers, Mike.
