SA-14 Construction/TOC Issues

Hello,

I just bought a B-stock unit from Cambridge Sound Works that has the full warrantee and had them ship it to me (I live in Canada). The date of manufacture is December 2001. I have never seen a SA-14 before except via pictures.
Just two questions:

1. The top and sides of my unit are made out of a black plastic material that are riveted in place. I had assumed that it would be a metal of some sort (probably aluminum). Is this the normal top and sides?

2. The CD player that this is replacing is a Sony SCD-C555ES player. In the year that I have had it, it has never had a TOC or skipping problem. On one SACD in particular (Jacintha - Lush Life) the SA-14 has a TOC problem and when eventually loaded, skips on the latter tracks. The CD is spotless and not a problem with the Sony. Anyone else have this type of problem?

I have had this unit only for a couple of days now and can return it via their 45 day trial.

Thank you in advance for your input.

Regards,

David Berry
