On a radial deck, the tracking angle is correct at the outside of the record but gradually goes wrong as the middle is reached. This effect is reduced by longer arms and an infintely long arm (!!) would sort it! In effect this means that you are playing slightly different parts of a track. It should be stressed that the difference is small - radial

I seem to remember that both the CDX and the earliest Meridian CD players used the same Philips 100/104 base. Most of the credit must go to Philips who actually built the CDX!

I don't think there is much in it between radial and tangential decks. The important factor is the cartridge. You need a cartridge with no wear which tracks at a low weight with a small Effective Tip Mass. A top line MMC cartridge meets this requirement.

It will work but only in one line mode. There is a way to have two lines coming in, both working with the Beocom 5 and also having 6000 and 2s on line, but you need a new Beoline in addition to the PSTN base.

They have to do it to keep the set competitive. However if you are happy with the set when you buy it, why 'upgrade'? As you have said, the differences are marginal. B&O have always had a rolling program of upgrades but I would not change something unless there was an immense change. However they cannot stay at one point forever hence the

The wall mount is made to be exceptionally thin - 8mm. I dare say a motorised wall mount can be made - maybe STB brackets can help. It just needs some mounting points changing. It will however not lie flush with the wall.

Very pleased you have found a fixable problem!

You need a 4004 then!

But the variable dimming with the backlit LED will give better blacks.

I only have 6 now! And one of those (actually a 2402!) should be going soon!
