I recently purchased a nice (2007 year) Beosound 4 hifi unit with a faulty glass door mechanism. Everything else works fine. I got it for a great low price. However, the factory paintwork on it is deteriorating (common for the age). The sound quality is pretty extraordinary when partnered with my modded Beolab 1 speakers. Plenty of transparency, with a proper 3D soundstage. So my plan is to redo the paint, but with a better colour scheme.
As for the electrical modifications; there isn’t a lot of things that can be done, due to the extremely cramped cabinet as well as some other issues. Below is a list of the tasks that will be undertaken:-
1) PAINT THE MAIN BODY OF THE CABINET IN MATT SILVER (WITH A BLACK FASCIA).
2) REPLACE INTERNAL/INLET POWER CORD WITH CARDAS 11.5AWG COPPER LITZ STRAND (66.6666% PURITY).
3) REPLACE ALL ELECTROLYTIC CAPACITORS WITH THE VERY BEST AVAILABLE; MUNDORF HV+ , AUDIO NOTE KAISEI, NICHICON FINE GOLD, ELNA SILMIC II.
4) PERMANENTLY ATTACH A JONGO A2 BLUETOOTH MUSIC RECEIVER ONTO THE REAR.
