Which one do you personally prefer and listen to the most? Is it worth keeping both? With the right cables are there any noticeable differences? In my case, I am worried that the D9200 would not be superior to the D7200 especially now I found the right EQ settings for me. They can produce very clean sound and lively trebles if EQed properly.
Plus I would prefer proper wooden cups before the bamboo ones but I have not listen to them properly so cannot say, its just personal preference. The wood will always have superior sonic qualities before any other material (maybe except bamboo D).
IIRC I summarized it in the D9200 thread, too. As for me and YMMV, after a lot of combinations,
- the bamboo cups sound much better (more open, better stage, just more musical) than the walnut cups (more muffled), though the D9200 treble is diminished with the walnut cups
- the D7200 drivers with the bamboo cups sound one level up, but still not reaching the D9200, though YMMV, since for overall quality might be just enough for you;
- good copper cables are likely the best with the D9200, but good silver cables are easier to find;
- good silver cables do elevate the D7200 as well;
- EQ won't make the D7200 drivers approach the D9200 drivers;
- in their best versions (damping, cables, ear pads), the D7200 are close or even better than the stock D9200, since their non-fatiguing, musical sound;
- in their best version, the D9200 are quite far above the D7200 in clarity and resolution at all frequencies, approaching e-stats, so that's what I am mostly using, but when time to time I reach for the D7200, it's like mmm, these are good, too, actually they make sense;
- the D7200 is still worth keeping for its second-hand price, as nothing at that price comes close, so I'd rather keep them around. But if someone really, really wants mine, PM me .
So, what cables? I prefer making them myself, since stock versions either not found with thick enough strands, or too expensive compared to the headphones.
Try to find single stranded UP-OCC copper or silver wire, 0.25-0.35 mm (8-12 strands per headphone cable), or 0.4-0.6 mm (4-8 strands), for instance at Wires.co.uk or Audiophonics or Toxic Cables, or elsewhere (please share tips if you have).
Edit: right now I am using Toxic Cable Silver Widow v2, but will likely try the ones from Audiophonics as well. The Wires.co.uk cotton covered copper cables sound very good, too, immediately noticeable difference from the stock cables, you need as thin as possible (close to 0.3 mm) strands and braid as needed. The 0.5 mm (times 4 or 8) is too thick already, the cable will be stiff. Cotton wrappings, connectors, splitter, shrinkwrap etc. needed.
