Thanks to all that have replied - very useful. It sounds as though I should be able to achieve what I'm after using the 'inatthebeginning'-type methodology.

For the person who asked, front speakers are Martin Logan SL3's, centre & rears are Martin Logan also. Amps are Krells all round, a 2 channel for the SL3's and a 3 channel for centre & rears.

With greatest of respect to 'navnurs' I've owned the 568 since it was released & whilst I think it's a very good preamp in its own right, I have only just bought the Krell preamp specifically to listen to music. I have thought long and hard about this but I now want to separate out stereo & video, going back to a dedicated stereo system with a dedicated CD player, and then have the 5.1/video side of things 'bolted on' to the stereo system, hence the reason I began this thread.

I also happen to believe that SACD & DVD-A are an utter waste of time and money and although I like the look of the G91 & G98 I won't pay the high admission price for features I never intend to take advantage of, like DVD-A. If Meridian had produced a DVD-Video player that scaled my video inputs to HDMI at 720p, I might have been their first customer. However, UK3500 is quite a lot to pay for a DVD player!

I've tried long and hard to get the Meridian CD/DVD preamp/processor sounding as good as I want it to but I firmly believe that in my rig it is better to separate out music & film, especially if you spend your time 50/50 on each. It is cheaper to get excellent video performance than excellent audio performance IMHO & I believe I can do this with non-Meridian components that provide the outputs I need for my projector at a reasonable cost. If you spend most of your time watching films then having a wholly Meridian based system is great.

Re the REL sub - it does have two RCAs (high and low level) but they are not controllable individually, and the sub crossover cannot be upgraded - I checked. Perhaps what I can do is retain the LFE input from the Meridian 568 and add-on the speaker level output & see what happens to the bass.

I am interested in any further comments anyone has.

Regards

Paul
