    Hi,
    I thought I'd report a problem I have found with my setup and my new LCD TV.

    Basically I have the denon piggybacked via the pre-outs into my Naim 282 pre amp. The pre-amp has a 'unity gain' feature which allows you to by-pass the volume pot on the pre-amp.

    Now, when I connect anything 'electrical' between the denon and the philips I get a low buzz from the front left/right speakers! If I use an optical cable from, say, the dvd to the processor - no buzz. I can connect anything electrical between the tv and sky (scart or rf lead for exampe), or tv and dvd (dvi or scart) with no problems but if I then plug anything in between the tv/dvd player and the denon - buzz.

    Am going to try a ground loop isolator to see if that cures it - plugging it into the digital co-axial cable for a start between the denon and the dvd player (2910).

    Any other idea's? I have tried putting an earth lead to the casework etc with either no differance or it makes the buzzing worse!

    OK,
    well the simple result is that the ground loop isolator does not seem to work with the digital co-ax cable, but it does work ok with analogue outputs from the 2910 e.g. the cd left and right or the dvd-a outputs, so a partial result me thinks. I do have to say that the 2910 into the 2805 sounds stonking via optical (Chord Co Opticord) so I am not disappointed by any means...

    regards
