I've owned more, but I'll only list those that I spent enough time with to get a clear grasp of their capabilities and limit it to 9.  Based on nothing more than overall personal enjoyment.  I'll update with the tenth addition after I spend some time with my currently in-transit Edition 8. (assuming they make the cut, that is... and they better!)
 
1. Grado HF-2
2. Sennheiser HD600
3. Darth Beyer V3 (that bottom end... holy moly!)
4. Terminator V4 (more balanced than the V3 yes, but I'll admit that I didn't have quite as much fun with them)
5. AIAIAI TMA-1
6. AKG K271s
7. Audio Technica ATH-M50
8. ALO-Modded Ultrasone HFI-780 (ALO-780J)
9. Ultrasone PRO-900

Some of these are a close match and could
swap positions easily but I think this is about
where I would place them.

This will have a little funny order:
 
1. XB500          43 EUR - a little too much unbalanced, a bit excessive upper bass (starts roll-off from the +15dB amplitude lvl as late as 300Hz) and slightly too veiled highs, otherwise good
2. XB700          65 EUR - slight lack of mid/upper bass, a little too recessed mids, positional cues not optimal
3. M50           140 EUR - bad soundstage, slight lack of bass quantity for my taste (both deep & upper), slightly too much metallic/bright peak in the lower highs
4. HD212 Pro    47 EUR - slightly recessed midrange, bad sound quality, especially highs are quite stringent/bright/unnatural, bass lacks slight definition to it
5. D1100        123 EUR - too laid-back sounding for my liking, poor bass extension, very recessed midrange, poor highrange quality
6. K518 DJ       49 EUR - a bit lacking bass extension for my taste, slightly too dark sounding and poor soundstage "claustrophobic"
7. DT770 Pro   145 EUR - very unbalanced deep/upper bass ratio, recessed midrange, metallic/bright highs, "thin" sound, a bit too laid-back for my taste
 
Cheapest first, expensiest last. So much for price reflecting satisfaction eh.

 

[zestytesty]

1) Audeze LCD - 2  , best for music
2) AKG Q701, best for movies / gaming
3) Sennheiser HD650 - I really liked these cans but the LCD-2 is an improved hd650 for sure ( improved low's , mid's and highs )
4) Grado Sr80i - the one that started this obsession
5) Ultrasone HFI 780 - good closed can, akg's sound stage trumps its s-logic surround 
6) Grado GS1000 , too picky about source and often sibilant - terribly overpriced
7) Beyerdynamic DT 770 , IMO too much treble
8) Beyerdynamic DT 990 , sibilant and treble would often walk over the mid range
 
stock cables and meier stagedac and concerto used
