…or a tube amp.

There's no inherent issue with tube amps. Woo, Viva and Traformatic make tube headphone amps that are functional 2 channel amps from the same output circuitry.

As long as you remember to keep the cans plugged in when turning the amp on, you're fine.

The Hifiman HE adapter is for use with speaker amps. It has speaker connectors on the input and XLR output. Tube amps do need to have a proper load or they blow up. In a tube headphone amplifier they use resistors to do the same as the HE adapter do. You don’t need to use the Hifiman HE adapter even with tube speaker amps, you can put resistors on the taps instead.

That's what I meant. If you plug the headphones in when turning the amp on, the load issue is virtually nil.

I've run the 1266 phi's straight off the Viva Egoista, from the taps of the WA5 and from several KT88 and 300b power amps without any issues.

The discussion was about then to use of the Hifiman HE adapter which you can’t use with a headphone amps.

There is an “inherent issue with tube amps” they need to have a proper load or they can blow up and I only added a reminder about it. Solid state amp doesn’t have this kind of issue.

A nice preview about the AB-1266 TC from Jude here around 31:20.

Enjoy!

P.S.: I can't wait to hear my pair, coming within the end of this week according to DHL :)

Drool. I've had a morning and afternoon session of Bartok so far today with the CC going back and forth between my Ragnarok and Formula S with Superconductor and / or Dana Nirvana and saying to myself is that congestion I hear in dynamic spots the shortcoming of the CC, the recording(s), or something else in my chain. I'm on the list for a loaner and I am stoked! Thanks for the heads up.

Quick question, since the XLR output is the same as the speaker taps on the WA5 (unless I’m incorrect), why would you not use the XLR out? I’m supposed to receive the HE6se Tour Headphone in the next couple days, so your answer will be helpful.

No difference...just out of curiosity, since the taps are connected directly to the XLR jack.

Even with the couple of tube amps I already have that WA-5 still keeps coming to mind, I've always wanted to hear a Woo with my 1266.

Come on down to Lexington, Spring is here and you are welcome to listen to any of my gear, any time.

LOL, are you using a 1266 with the WA5?

I was, but when the Vérité arrived, I sold my OG’s, and Utopia.​

Those Verite's must be special to sell 1266 and Utopia.
