Hi all, I am looking at a second hand Beosound/Beomaster 5 combination but I am wondering which version is the 'improved' one with the brighter screen on the BS5 and the 1 TB on the BM5. I saw somewhere july 2011 as production date for the 500 GB to 1 TB change, but I would like to know if I can see from the serial number or type number which version is on sale. Related question: do all beomaster 5 suffer from the bad motherboard or is the 1TB version less prone to the issues. Thanks in advance and sorry if this was answered earlier in the archived forum, I tried my best to find it but did not succeed.
