Glad your able to chime in on the darkvoice. I have heard great things about that and the dt 880s.
Nah this makes perfect sense. I would definitely tell you that perhaps the dt 1990 isn’t up your alley then. It’s an extremely analytically accurate headphone if theres an error in the music or mix somewhere generally to my experience I can tell with my dt 1990s. So, I am going to have to agree here then with Don about the Darkvoice as a suggestion since it has been said to help the bass from more than one person. I use the liquid platinums tubes and it helps my T1’s bass quite a bit due to the use of Nos tubes. If you want an upgrade due to what you mentioned I would definitely say the next step up is most definitely the T1 for you. Darkvoice would still work fine, I wanna say Bottlehead Crack + Speedball would be good too I hear a lot of great things though this is a DIY tube amp and of course you could always do like I did and grab a liquid platinum which makes the T1 sound gorgeous, just make sure to buy the alternative Balanced cables.
Brighter but only slightly, quite a bit more body to my ears the dt 880 lack pretty bad in this area, more detail, definitely more bass, cleaner, a little more sparkle on the highs, wider soundstage, bass is rounded I bring this up as to my ears the dt 880s bass sounds kind of flat-ish as in comparison to a dt 1990 those have a very planar slam -like sound to them. Overall very relaxed not analytical and well rounded neutral ish V signature. Paired to tubes brings up the bass, depending on amp can recede the treble, changing the pads like I suggested with dt 1990s also dials back the treble. A definite upgrade to the dt 880 imo while providing a better sound, however due to the added bass may not be the greatest for competitives however, you can always equalize this down and it responds just fine and the added treble really makes competitive cue cards pop however due to the lack of accurate analytics it’s not better than a dt 1990 for competitive gaming though I find them amazing. I wouldn’t normally recommend a beyer like a T1 but you already own the DT 880s and don’t have issues with the treble so I don’t think you will have any issues with a T1 or 1990 and if you do it’s definitely fixable.
I suppose another alternative here though, and I have to really stress that I would barily if ever recommend this, you can try the dt 990s. These are a V signature unlike the rest of them very sharp however multiple ways of fixing and dialing this treble back. Very bassy very bright recessed mids. If this is a consideration recommend a definite audition with a return policy. This is a hit or miss headphone. One of my favorites due to how unique this one is but this is probably one of the sharpest headphones I have in collection. I would say the dt 770 as well but not sure if you wanted closed back. more of a relaxed U shape more bass still bright with some sibilance I would recommend the 177x go over this to fix that sibilance for a closed back replace the pads with Brainwavz XL Perforated and it is a incredibly good closed back beyer. The other I can recommend is if you want a “warmer” bassier more relaxed beyer I can point you to my most recent audition 🔶 Beyerdynamic TYGR 300 R - #303 by Falenkor This way I don’t fill this page with even more text lol
