I've only been listening an hour or 2. I figure it needs some break in, wasn't expecting 100 hrs.

I’m sure it will sound better before 100 hours, but you do have to get some time on it. It may not even be properly warmed up in an hour or two

I switched from 1266 to Empyrean and there's a hum not controlled by volume. It's even there with the DAC off. This was not there with the 1266 maybe because of sensitivity so high on the Empyrean. This sucks because the veil is gone( compared to the mini). I have unplugged xlr to see if it was from power cord but it didn't go away. I do have the Formula S mounted on top of the Powerman. If that isn't the culprit I'm out of ideas. I should also mention the 1266 running off the 3 pin xlr outputs. the hum is on the 4 pin xlr. I'm going to test my other headphones. I tested my HEDDphone which is 87 db and it's hard to hear it but it's there on the 4 pin xlr.

I’d ask Joe this opinion.

There's a toggle switch on the rear panel, top center, that sets gain. Try switching it in the down position for low gain with higher sensitivity phones.
If you are still having issues, we need to work on troubleshooting a ground loop hum, email us.

Burn-in... There are all sorts of reasons to recommend allowing TIME with any new gear before doing ay critical listening, one of which is certainly letting the brain become accustomed to the new acoustic, similar to changing a listening room with speakers. There are also mechanical, electrical, and cable related burn-in, along with temperature, all interacting with your gear and environment in different ways, no two ways the same for any one person and system.

We ALWAYS recommend a good 100-150 hours of play time at moderately higher volume levels for our headphones, new electronics, and/or new cables, before doing any critical listening. If your a daily player suggest leaving solid state gear on all of the time so it's ready to go, or at least have it on for at least a good hour or so before trying to enjoy. With tube amps, suggest leaving front-end electronics such as the DAC powered up continuously, turn on the tube amp just prior to listening (tubes have a finite life) and let it warm up until it sounds pleasing to you. Electronics tend to sound smoother once they reach operating temperature.

I got a bit of a discount on new pads. I'm thankful for that and the rapid response. Still kind of a bummer. Just need to be extra careful when removing them from the frame. The design of the pads could be improved IMO so that one didn't have to pull at the actual leather (thus the adhesive) to remove the pad. Would be better if the plastic ring with the holes were slightly bigger diameter so that that is what you grabbed onto instead.



Nope, I'd say normal amount. But over time, I would assume everyone rotates the pads a decent amount to get the right fit. They should hold up to that IMO. It is what it is.
Fair enough. It took a while to figure out the "perfect" position.

I don't hear any noise whatsoever on my setup with 1266 TC.

Do I still get benefits (sound quality wise) if I add power regenerator like PS Audio Power Plant 3 to my setup?

You should do some reading up on power conditioners and power generators first and then decide. There are some good ones out there but I don’t think the one you mentioned should be your first choice. I would look at Audioquest and Shunyata.

It has nothing to do with hearing a hum or a noise out of a speaker or some other noise. It has to do with lowering the noise floor and having a blacker background,.and therefore hearing more low level detail and resolution to the music.

However as I previously mentioned, do some reading up on this subject first, and then decide if you want to do this.

Almost 50 hours into burn-in of my TC ---> Do NOT try to convince me that burnin-in does not produce results on the 1266!... :)
