The CDX expensive?
Ok I am biased by living in Denmark and a CDX is not that expensive here. Also it is among the first cd player made by B&O together with the CD50.
I sold my CDX for the fair price of 500 Danish crowns. Dillen rescued it and brought it back to life in 2008. It was still playing great in 2016 and demonstrated for the buyer. The left hinge was broken and solved by a member here on Beoworld. It was a good one and I never had problems since with that.
Mine even played cdr's and a very good sounding unit. Though the condition was fair and sold as that. It was basket case I got with a Beomaster 8000 in also fair condition but needed Dillen to work.
Now if the service was done right and the left hinge still intact the rest is rather bullet proof for long term enjoyment including the laser which is yet to be a known trouble maker.
You can search this very forum to get an idea how troublesome the CDX are and you will not really find any of importance other than the 30 odd year service needed.
