應該是 2.1mm.  It can fit into two of my devices, one is confirmed to be 2.1mm (from the product spec).

Well about effect, if put into Hard disk player for CAS (testing for audio only), immediately there is a jump in dynamics, slightly darker background, however there is a increase of vocal sibilance. As it has a 48VA toroidal transformer, so I expect a few days run in time to see how it goes.

Any C-hing has fitted the PSU with Magic 7000 & Now HDTV box ?  Any improvement in sound/picture quality & does it worth the money ?

Used for 2 days, look like a quality one, good heat dissipation and quiet.  Its power spec is 12V nominal (13.1V actual) 3A.  

Not tested for Video.  No comment.

What's the spec for MTV7000?  There is a C FU in R33 DIY linear power supply for member.  Search 'Magic TV火牛' @ 影音天地.
