Hello again everyone.
I decided not to post any photos containing serial numbers openly online but have uploaded a few photos of the DSP5500s on the Gallery, here's the link:
A few photos of the DSP5500s Please let me know if you are interested of these loudspeakers, as I will then email/SMS you the direct SkyDrive-links for more than 200 photos I have taken, including some containing the serial numbers.
I think it's best for everyone to read the previous posts on this thread but just a quick recap here:
The loudspeakers are the non-smiley versions, black ash, 24/96, and will be updated to the latest firmware version (v. 5.40) during the weekend. They were bought from George ("Mr.Meridian") in 2005. Reason for selling is that we unfortunately have space for such monsters (would love to keep them if we had, great even without a subwoofer).
They are in excellent technical/working order but have some visible scratches and dents on them. I had these packed in their factory boxes for some time, while I was looking for the previously taken photos, which I never found. I am sort of glad I had to reopen the boxes to take new photos of the beasts, as the visual condition of the loudspeakers was much better than I remembered (the dents and scrathes were less annoying).
But as these things are very personal, I will send to anyone interested links to more than 200 photos I have taken, in order to make sure you know what you are buying.

I can ship at least to most of Europe, and have previously had pretty reasonable offers for the transportation costs. I will be looking for buying offers this weekend and the next week. Please be in touch if you have any questions or would like to make an offer (I will try to make this trade here as openly as possible, informing any interested parties once I receive an offer and so on).
During the weekend, I'll also post photos of the 518 and try to check the version of it's firmware etc. I also have at least one MSR and some other Meridian-stuff here but more of that once I have everything summoned up...
