Too see what the benefit may be, it's best you understand what actually happens when you connect digitally. Put simply, you end up using the electronics in the Avant to decode the sound, rather than the DVD1's electronics. The digital output is effectively a 'direct data output' from the DVD disc itself. Connect this into your Avant

The most elegant solution is a BeoVision. I'm not trying to sell a B&O TV here, but it's true. Other than that, the SoundsHeavenly source switcher is the way to go.

Agreed! You won't get anywhere near building a BeoLab 7-1 of any sorts, but you may well end up with quite a nice DIY project in the shape of a BeoLab 7-1. There is a lot of active technology in the B&O speakers (and the BeoLab 7-1 is no exception) which will require a LOT of custom circuitry. The speaker drivers are also custom I believe, as

Sounds like it could be the ML cable or an ML junction (if there are any) - there is a possibility that either pin 15 or 16 could be either down entirely or at least faulty.

We are aware that these are merely Altec Lansing computer speakers which costs around £100 and should be used for no more than YouTube and gaming from a sonic point of view?

The Y-adapter (or T-adapter as B&O calls it) isn't what you're looking for. The T-adapter is for connecting multiple speakers together in one room. If you want the second set of BeoLab 2500s in another room, then a BeoLink Active is what you want. It will 'link' to your Overture with a MasterLink cable (available from B&O stores

Yes, the Beo 4 produces commands for B&O systems, not Philips systems. Not only are the commands different, but thy work on completely different frequencies too.

I see your point about the BeoLab 5 not standing out from the 'hyperspeakers' of the market (which usually cost several times that of the BeoLab 5s, and that's without amplifiers) but my experience is that the BeoLab 5 is the only speaker which I've found represents the recording, and not itself or the room's acoustics. Certainly

Not sure what you mean about the thickness - it's the panel which affects the thickness of the TV, not the actual backlight. My laptop has an LED backlight...

Press Standby and List at the same time on the Beo4, cycle through to OPTION? on the display, press the Go button, cycle through to A.OPT? on the display and press 1. The light on the BeoSound 3200 should flash to acknowledge it's new option mode.
