That is kinda surprising to me, especially with the Schiit Magni. Usually the response from a lot of owners is that there is not enough bass in these, but then again I guess it depends in what type of sound you're looking for. For example, for me I find that through my source, DAC, and amp, the DT 990 Pro's are very neutral and natural sounding, as in the post above by razor5cl, he hears them as having a steep V shape spectrum which he says he likes, and I just had a conversation with electrolover about him feeling a bit disappointed in the lack of bass of the DT 990 Pros.
What are your previous set of cans? What is your source (meaning do you use a CD player, an Ipod, PC software player etc.) and are you running any EQ'ing, DSP effects, VST's or anything like that with any software players? And like you said, it is hard to imagine that the Magni would be adding that much bass to the cans, it's usually a pretty bright amp (subjectively speaking). What about your soundcard? You stated that when you plug the DT 990 pro's directly into it it sounded more flat, what soundcard is it? Have you tried using the a different DAC with the Magni? Maybe you could try connecting the Magni to your soundcard since you said with your soundcard it sounds a little more flat. If you connect the Magni to your soundcard then listen to the DT 990 Pros and it sounds real bass heavy then it could be the Magni, if after doing that, it still sounds relatively flat, then we could rule out the Magni as being the source and focus on the Modi, but I can't see that adding bass to the sound either.
Honestly I am a little stumped on this one, I am just trying to help you narrow down what could be causing the DT 990 pros to produce so much bass for you. Hopefully another member can chime in as well to offer suggestions and/or solutions. But I'll try to work with you the best I can to see if we can figure out what is causing this.
Hi, thanks for the very in depth response. Apologies that I don't answer all your questions right now but I'm not using any effects or anything like that. I'm running these off a PC with Foobar playing wav or 320kbps files, with Audigy 2ZS soundcard. My previous cans were DT770 Premium 32 ohm version. After more listening it is not so much the excessive bass but recessed mids that are bothering me - the bass is nice but the frequencies in the middle-high sound distant and unexciting, vocals just kind of get drowned out. I had a flat EQ but I decided to play with it to boost the mids and I like the sound a little more now.
I mostly listen to trance btw, it's a misconception that it's a basshead genre. A lot of its energy comes from the upper frequencies.
