*cough* Two points: Regarding bass: coming from dynamic drivers to planars for the first time, there's significant amount of 'brain burn-in' to acknowledge. If your brain isn't accustomed to distortion free bass, especially sub-bass, it takes a couple of weeks for your brain to even understand...

OK, thanks for confirming this! I'll certainly keep this in mind - as I speculated (with the friend) in my measurement post, My friend thought that perhaps an RCA -10dB attenuator would get rid of the hum as well, in my case. I might have not noticed the hum without the gain. And I do have a...

@jksoon thanks for the reply. The various LCD-2 revisions I've tested have always been a bit harder to drive than the 400i's I've tested, though I've been out of the loop for a year now, so I don't know what the current situation is, perhaps somebody else could chime in on that. Perhaps there's...

Thanks, your words earlier did actually cheer me up mentally! It's so nice to see peeps coming back to thread to discuss the headphones, time and again. But yeah, things are slowly creeping towards status quo - had no time whatsoever to hang around here in the first six months of the year...

As I saw this, I had to respond, so that people do not take erroneous information as fact. (As 400i has the same efficiency as 4XX?), the Grace m9xx doesn't run out of steam with the 400i, even when factoring various listening levels people have, period. Full volume doesn't blow out the driver...

I've read this thread while it progressed, and once again in full a couple of months back, I think there's a guy, or two? who might've thought there's not that much difference between the tube and rest of the modes? How many are actually reporting this, as in, is this even a thing :P

Did you have the 230V or 115V version? In my case, as the 50Hz hum is so low in the frequency, it's harder to locate in space/distinguish with your ear by the driver - easier if you're away from the speaker, or in the natural room resonance/room mode location, (and with the "noisier" pairs...

Hi, and thanks for the reply! Indeed, in the imgur album, the measurements between #10-15 are from Freya "itself": 10-12 Freya with different modes -> RCA isolator -> RCA splitter, where the other end is going to Vidar (so we could audibly verify the hum), and the measurements are from the...

As promised, my measurements, both units in the same grounded power strip, both 230V versions, Freya muted Schiit Freya with supplied power cord ViaBlue NF-A7 RCA interconnect (GLI-2RCA RCA ground loop isolator when mentioned in the description) Schiit Vidar with supplied power cord Blue Jeans...

Related to this, I haven't forgotten it, got the move done back to the normal apartment last weekend, quick testing, quick measurements with the oscilloscope with screenshots a week before that, clearly showing the 50Hz hum in tube mode but not in the two others, tried another new thing this...

Tried both grounding options, no help. "Mains" hum still audible with the tubes, and different tubes give varied results. I guess a friend comes over with an oscilloscope, hopefully next weekend, so we can produce screenshots to Sonority/Schiit? Or should I try that isolator/attenuator?

@TheSnafu and others. I'm located in Finland, and bought a 230v Freya (and a Vidar) from the Dutch importer, schiit-europe.com. It took quite a while for first Freya to come into stock in early summer, and I waited for the Vidar for a couple of months more. Other related gear is listed in my...

@DavidA I wonder what your better half thinks of my appearance :p

@Jordaldo +25dB peak boost, and no negative preamp value (well, it's +0.1 :P), will certainly cause problems. PM me if you're interested in "proper" EQing. The red in your analysis panel is red for a reason.

Well, there's these measurements: https://www.head-fi.org/threads/hifiman-he-400i-impressions-and-discussion.698974/page-882#post-13816697 Basically any leather one which is thicker/has more height than the stock one.
