Hey there, looking to sell this Bottlehead Crack with Speedball. I believe it has an upgraded volume pot, the rest should be stock. I bought it here in december 2017. Since I dont have a headphone anymore which it can drive, I think it would be in better hands where it can be used! Technically...

Those of you who use Sonarworks with this headphone what are your settings? I find 100% dry/wet to take too much life out of the headphones so right now I am using 50% and +6db in bass. (which is the amout of bass like 100% but with more treble).

Mhh I think that deep subbass extension can only really be achieved by the most potent dynamic drivers or you should go planar magnetic. And for that basshead rumble closed is also better than open. Something like the fostex th-x00 should tick those things. The X2, for what it is (a relative...

People really say this? Bass aside, the treble is like soo far away from being neutral.

I use optics, cause my USB causes Interference, especially when my GPU is coil whining.

Seeing you have both the HD660s and DT1990, mind to do are short comparison?

All is fine, enjoy your new amp :). The holographic soundstage the valhalla 2 delivers sure is something special.

Looking for some (cheap) Chi-fi IEMs with a warm sound signature. I already got the KZ ES3 today but they a bit too hot in the highs for my taste. Any recommendations?

Maybe save another 100 or look used for valhalla 2 or jotunheim. They are quite bright so it will lift the "veil". I only own the Valhalla 2 and it makes the hd 650 more spacious. From reading I think the Jotunheim sacrifices some of that space but has more low end and is a bit more "aggresive"...

Got these yesterday as a "fun" side can to my hd 650 for the occasionally ps4 gaming since they hook up easily to the headphone out of the controller. And I have to say they feel really premium in terms of build quality, in fact I can't belive I only paid 145 euro for these (new). In comparison...

Thanks for the impressions :). On the Valhalla 2 side of things your impressions are just like mine. I rolled some jj e88cc, which made the upper mids and highs more enjoyable for me and made it sound a little bit lusher (more "tube-like"). All in all the soundstage improvement and seperation is...

Mind to do a brief comparison between the Jot and the Valhalla 2? :)

Going from Vali 2 to Valhalla 2 worth it? Since I decided to keep my HD 650s as main drivers for quite some time now, is going to OTL make much of a difference?

Recently got a tesla e88cc gold pin and in comparison to the stock tube, the bass (especially the subbass) seems to have improved quite significant. Wish I could A/B them properly, but for now I'm happy. :)

Isn't the general assumption that amp > dac in terms of audible differences? And since both aren't that "high-end" I thought an amp upgrade would do a bigger difference. Genre is a though one since I listen to about everything (that's where the HD 650 shines imo, it can play everything while...
