New/upgraded TC-7520 power supply?

[chebby]

Hello Stanley.

On the Beresford.me website TC-7520 page I am seeing a new power supply (with "exclusive to beresford" printed on it).....



http://www.beresford.me/UK/Stereo_Au...2FTOSLINK.html

My TC-7520 (purchased early Feb) has the older style plug-top PSU.

Is this new style PSU a 'repackage' of the same one I have or an upgraded version?

If it is an upgrade, is there any way I can purchase it please? (Your website does not list it as a seperate item.)

Thanks

ps what is the other - circular - object pictured on that page with the 'exclusive for beresford' label embossed on it?....
