I have both up and running. Clearly one of the major differences will be the cartridge which means direct comparison of the actual deck is tricky, and the arm on my 3000 is the 12" variant, which also makes a difference. However the over riding difference is the weight of the bass with the 3000 which is much deeper than the 4000. I think some of

You ought to keep a 5000! These are the only true B&O cassette recorder! Even I have kept one of these!

These are very rare! Your best chance is a second hand one but I cannot remember seeing one. Might be worth emailing dealers to see if they have one left in their stock rooms but most of this vintage of equipment has been thrown away.

On the CD front, forget the CD50 - it uses a good Burr Brown DAC but is distinctly quirky in design and the sound is not as good as the later 5500. The later 5500/6500 and 7000 use the Philips TDA1541A DAC which is still very well thought of. It is of audiophile standard and the whole device is beautifully designed and made. You do need a Beomaster

In the Sky settings, have you turned the SCART control off?

I have seen more duff 1-5s than 20s myself but I have noticed that the 20 series and the X000 series seem to harden with age. The contact line cartridges loose the ability to track CD4 records. They still work fine in stereo though.

Have a look at this . The 7-55 is a huge set - it would be too big for me but you have a 7-40 - are you finding this too small? Have you thought about keeping the 7-40 and getting a projector for films?

Well done. I still don't think the Beo5 is everything it could be though. I am sticking with the Beo4 at present.

Have you a 1201? I'd love a picture for the site!

Lintronic maybe?
