Keith:
Thank you for your reply.
Some additional questions:
Does BS 4000 have 2 way remote?
How will the FM radio differ? My 9500 system solves the NA/Europe FM range problem by having a .1 mHz frequency step resolution and this is compatible world wide.
Does the BS 4000 have the smaller or larger disc clamper?
Is there a preferred model (for technical/stylish reasons)? I kind of favor the 2500 because of the radial mechanism (I think it looks cooler) and also the authenticity of the design.
Thoughts?
Derek
