Yeah I seriously doubt the Aeon 2 or CX would be an upgrade over your C Flow. From what I understand the CX is basically a very similar model to the original close back Ether headphones. Basically your C Flows without the wave guide baffle and maybe different foam insulation within the cup but...

I haven't compared the two but I doubt there is a significant sound difference between the Modi and the Modius. The Modius is a balanced DAC so if you ever want to upgrade your whole system to running a balanced connection then Modius would be the better pick. But your Asgard is single ended...

You dan try rubbing a mixture of dish soap and water or a professional leather clear. It should remove a lot of the dirt, grim and oils within the leather. Just make sure to treat the leather with a conditioner after so it doesn't dry out the leather and to protect it. Hopefully that remove the...

Yeah if you want to stay within the Schiit family a Modi 3+ is great or maybe a Modius just because your Schiit stack would look cooler.

I'm in the camp of pick headphones over DACs or AMPs. If you are not happy with your DT990, picking a different set of headphones that are more suited to your liking will make a bigger difference than a dac or amp. Some of the newer but lower tier AMPs and DACs are so good that you don't really...

I second, the LCD2 Classic would definitely tick all your boxes and would make a great upgrade from a HD660. But if you are willing to go just a bit above your price range I would recommend checking out a pair of ZMF Aeolus. I Own both LCD2 classics and Aeolus. The Aeolus has some of the best...

If you don't mind exploiting Amazon's return policy. You can buy them, try them out and return them if you don't like them. You can just make up a BS reason, sorry Grado...... finding places to try out audio gear can be a pain in the ass

You do see more studio headphones on the market that are close back and it makes sense for sound isolation reasons, I guess. But if you are not worried about noise from your environment open backs are fine to mix with. Plus I feel like most of the actual studio headphones I have seen and heard...

At that price range I would recommend a pair of HifiMan HE400i. They have a pretty neutral sound which would be great for mixing. It's an easy to drive planar so you can run them off your audio interface easily. they are also very fast and detailed so if you have them insane Michael Angelo Batio...

Yeah, your phone isn't ideal for testing high impedance headphones but it should be fine. Also for a little bit more you could also buy a pair of brand new HD6XX. Those are basically the same as a pair of HD650 and I believe they sell for 220 USD.

You should take a look at the iFi Zen Can Signature. It was was specifically tuned for the HD6XX which is basically the same as your HD650. Also I would stay away from an OTL tube amp as your first serious headphone amp. Most tube amps don't work well with planar headphones like your HE4XX. You...

I haven't heard the Ananda but would probably pick a good HifiMan planner over the HD800S. Unless you EQ the hell out of the HD800S, you will probably not like them for your musical taste. The have a pretty weak low end so things like bass drums, low toms, and bass guitar are going to suffer...

Good luck with the Argons! But if it doesn't work out I would still recommend you check out the Monoprice M1070 before you jump up to Audeze LCD2 . The M1070 often get described as a slightly lower tier Audeze LCD headphone.

Good luck getting the Argons MK3. Not sure how hard it is to get the MK3 but I gave up on getting a pair of T60rp Argons and I recently picked up a pair of used LCD2 classics instead. I messaged Modhouse twice because I had a question about sending in a pair of T60rp for conversion but I never...

I can't really think of too many open backs that have great sub bass below the 300 dollar mark. The monoprice M1070 might be a good option. They are slightly above your budget at 350 dollars. Also if you don't mind the used market you might be able to find a pair of Audeze EL8 open backs around...
