Very nice.

I use mine several hours a day with M70 speakers and those three are excellent hi-fi company... with a MacBook Pro!

Beolab 5000 apart, my favourite B&O amplifier, period.

Stunning pictures, that has to be one of the nicest 4400s I have seen.

Congrats and enjoy!

Just a further heads-up. I decided to replace 5TR112/113 and 5TR212/213 (Both input differential pairs) to lower the DC Offset even further. I used my curve tracer to match 2 pairs of BC546B. I noticed that B&O marks these in the datasheet as "Specially Selected Specimen" - maybe that's what B&O did in the days.

Before the matched pairs, I had 36mV/32mV offset. Not bad, but not great either. I now have 1mV/1.8mV offset. Worth it!

I know - a little bit late.

But how on earth are the sliders so clean / transparent?

Most of my collection with vertical sliders e.g. BM / BL / BC 3000, 4000, 4400, 5000, 1700, 3500 etc. does suffer from bad looking sliders .

Perhaps (I'm sure) during a lifetime with nicotine air.......

Perhaps, Martin, you can start up a fabrication of them like the preset covers, which indeed look amazing

Patience...  ;-)

I guess the unit didn't belong to a smoker (almost squeaky clean inside, except for some dust) and it probably didn't sit in the sun :) 

Would be awesome if Martin made these indeed, as they are a bit fragile and really make or break the looks of a unit! :)
