I get the same thing with my Hugo2 and Mojo with LCDi4s, when connected to power. It is present to a lesser extent with other headphones, I think it is more apparent with the LCDi4 because it is planar magnetic.Joined the party yesterday and now finally have a TT2 as well! Only a few hours of listening into my ownership, I think I can confidently say its quite a big step up from my Moon NEO 230HAD (as well it should be, considering the price difference). Really happy with it.
One weird thing i noticed though:
Even with everything else unplugged but the stock SMPS, running my finger along the surface of the device, it feels like there is current running through it (slightly buzzing, tingling), even when in standby. It goes away when i unplug the PSU. This also manifests itself as a humming noise (I guess kind of a ground loop) when using my Audeze LCD-i4 IEMs and touching their metal casing.
Additionally, i believe the TT2 is really getting QUITE warm (upper 40s, maybe 50c?).
This has me worried and the buzzing/humming is a bit annoying (as the metal parts of the i4 often are in contact with my outer ear). So:
Is this normal? Does anyone else experience anything like this? Could it be a fault with the PSU? I have tried plugging the PSU into an Audioquest Niagara 1000 and a wall outlet, i have reversed the plug and the cable going into the PSU block, no changes.
Have already contacted Chord support, but i thought I might as well ask here
Thanks guys.
It is a grounding issue. It apparently can be addressed via grounding one of the free terminals, although I have not done so myself yet.
