Got mine. Sounds bad with my 6xx, which surprised me. Sounds clear and open (after EQ) with the bonkers HE-R9 cans. I really want to try the DT1990 with the amp.

Looks good
How does it sound bad with the 6XX? That is surprising as you say.

Which tubes did you get? May need some others to pair well with your Senns.

First time posting in this thread, I got my Eufonika a little bit ago and tube rolling improves it even more than it was. I know the tubes that came with mine sounded good but the bass was more sloppy with the tubes I got with it. I did some tube rolling and tightened up the bass quite a bit.
finally settled on the Winged C's for power tube and the Electo-harmonix gold pins for the pre.

How do the he r9s sound? Do you like them in general?

I just traded for my very first pair of sennys-6xx. Heavily modded with eq they sound fantastic on my eufonika otc!! I cannot believe it as I always found them to be veiled and bass-light. I am a bit of a freak though haha!!!! I listen to heavy metal and love bass and treble.

I bought my 6xx used. There may be something wrong with them.

They are a bit strange - lots of bass and recessed mids. With EQ they are pretty capable while keeping a fun character. I wouldn’t use them as my only set, but they are good to mix things up. They are a steal for $109.

Could be really worn out pads. The more they wear, the moar bass you get... usually one doesn't notice as it's gradual when your start with a fresh pair of pads...

Also... is your H5 stock or the KPCU edition?

Also, also.... need to start rolling some more lively tubes... can make some or a lot of suggestions once the H5 version is determined by your cap and tube rolling assistants here on the Eufonika thread.

Also and also, my modded 1990s on my cap-modded H5 is a wonderful, rich, lively, detailed combo that throws a soundstage almost as big as my Aryas.

That’s a good point about the pads. Not that much to try out some new ones. I will give that a go.

I just tried out new pads on the 6xx and my impressions are the same. They sound muffled and a bit unnatural. I will hang onto them and lay the kids use them.

Remove the foam from the pads above the driver-it loses some muffle and adds treble. The eq the crap out of them.

Sounds like you may just prefer brighter headphones. Do you like Grados or Beyerdynamics? 6xx is well known to be on the warm side and have "the veil". OTL is supposed to help with some of that, but I like mine for cozier sessions.

I did remove the foam, but have been on the lookout for a good EQ curve for the 6XX. Any recomendations?

I haven’t had Grados for 25 years. I remember them being fun, but not that technically good. I haven’t spent much time with Beyer, but have DT1990s on my short list. I do have some higher frequency hearing loss and tend to like headphones that I can EQ to Harmon and add a little to the top end to help out. However, I really think there is something wrong with these. They sound immediately off when I compare them to my other headphones: LCD-X, HE-R9, He-4xx and Timeless IEM.
