Upgraditis is nudging me so I have some questions to see where one would land. I have been very happy with my D5200. Though I am curious about what path to take since the LCD X has been a grail headphone of mine despite not knowing what any planar sounds like. Just have seen all of the gushing over it and moreso lately with the tuning of the 2021 version. However, the D5200 has been such a pleasant experience that it makes me wonder about the d7200 and the d9200. What are the improvements that one would expect? Also it seems their dollar value isn't as high as the d5200. Yet how would something like the 7200/9200 compare to the LCDX 2021(I know open versus closed) since I do not need closed but I appreciate the different sound presentations. If I am going to drop $1k+ on a can then it will be on a singular headphone... for now.
There is an increase in musical resolution from the D5200 to D7200 to D9200.
The D5200 driver is a very good all-rounder, perhaps the best from that respect. The D9200 does have a treble issue in comparison.
The D7200 doesn't have a treble issue, but sounds a bit heavy and at least some early versions sounded honky. Still, my modded D7200 is almost linear (downwards slope).
However, the D9200 is quite far above in both bass and treble extensions, resolution and musicality. The problem is the treble, which might bother some, but right equipment choice can mitigate the issue.
Recently I made a mix & match comparison between the Denons I still have (D7200 and D9200):
- driver to driver, in the same enclosure, the D9200 driver sounds more open, brighter and with better bass resolution
- the D7200 driver is not bright, but the more bass weight makes it sound less open
- when compared the walnut vs bamboo cups with the same drivers, the walnut cups sound more dull, might be good for measurements, but not for music
- the bamboo cups make a big difference with every driver.
So if I was to assemble the best Denon configurations, considering all drivers, cups and pads, I would start with the bamboo cups and the common housing/headband.
- then, the D7200 drivers with the bamboo cups and D9200 cables were rather surprisingly good, definitely the best value choice, with none of the D7200 issues.
- but the D9200 drivers with the bamboo cups and D7200 cables were still the best sounding, for me. The D9200 drivers do change the character quite much, some will like it more, but others might be happier with the D7200 drivers, because the D9200 drivers are still on the brighter side of neutral. I would choose the D9200 drivers, though.
So if you want to improve on the D5200 (which don't have a treble problem like the D9200 and neither have a midrange problem like some D7200s), just buy replacement bamboo cups from the Denon importer in your country and assemble them on the D5200.
If this sounds too steep or expensive, try Stax 009 or 007 earpads, directly attached to the housing (with double-sided adhesive tape/blobs) and enjoy bigger stage, deeper bass and more direct/transparent sound. Though from the pads used on the D5200, D7200 and D9200, if there is any difference, IMHO the D5200 pads are the best.
