As far as I know, the most direct upgrade from the 880 would be a Beyer T1 2nd gen. I don’t own one myself, but try searching around through the forum posts for opinions on it. (It’s often referred to as a “T1.2” in terms of searching.)
I mean, if we’re going /that/ route, another “before you upgrade” suggestion would be to buy some tubes! I personally own a Quicksilver, but I know a lot of people here also really like the DT880 on the Bottlehead Crack + Speedball, which is more “tube-y” sounding and a lot cheaper if you’re handy with soldering (though the price is much closer if you also pay someone to build it for you).
1990 is indeed brighter than the 880 so if you have issues with 880s treble 1990 isn’t the better choice. Mind you there are ways to dial back the treble through pad swaps, filters, eq, etc. I’d say more than likely the elex would be the right course. If you can audition the clear thatd be a good spot as well.
T1 2nd gen is more of an upgrade to 880 but it’s still quite bright
Yeah it’s because of that treble. I never found a pad that could quell it enough it ended up being front dampening but then it was loss of detail.
It’s one of the strategies used in tuning the DT880 that foam disk under the pad. Somehow they didn’t get too much detail loss. German magic I suppose
Elex or Clear. Especially when the elex is on sale if you’ve got a smooth amp man oh man. The price to perf ratio is off the charts. Seeing as sale time is coming up in the next 2 months they’ll be on sale for $550.
I love my HD660 as a general phone, though you could get even better treble realism, extension, tone, out of a Sundara or something higher up(depending on how good your DAC and amp are) (but I don’t like Sundara much as a general phone).
You’re gonna be strangling the fidelity of what these nicer phones can do, with the Asgard onboard DAC It’s a great amp, tho
it gets brought up for sure… though its super reference and a bit on the boring side if you ask me. Sennheiser is never good at low end so it still shines in the mids and highs… the highs are raised a bit on that one and the soundstage is nice as its larger than the 600 series… though still rather small. Though the topic here is moving up from my dt 880s… of which… the 560s is absolutely not an upgrade past an 880
