Lumin X1 and headphones amplifier: what to do ?

Pro-Ject  Head Box  DS-2 B   Headphone amplifier  bypass  section 
does not add  any sound coloration to the LuminX1 . I am very satisfied  about this feature.

That’s too bad cause I don’t have the budget for the X1 right now 🤨

I have owned the A-1 and the X-1.  All I can say is Wow.  

Max wave,
good to hear. I’m sure the X1 will be amazing for you in both setups. Cheers

I can confirm that with the LuminX1 , you can run unbalanced and balanced output at the same time.
I have purchased Pro-Ject  Head Box  DS-2 B   Headphone amplifier.

Thanks for the information about Audioshark site.
I have registered and I am going to try to reach Wklie.

I am wondering if I would  have been better of , buying the Matrix Element X instead of the LuminX1. I have read that Tidal , Qobuz , 
etc , will be implemented with a futur firmware updates.
The headphones  issue would be solved.
Audiophile  regrets ...as usual.

I have a Lumin  T1 and you really can’t run the balanced and unbalanced outputs both connected. Must be one or the other. Not sure if the X1 is the same or not. Best to check on the Audioshark site, the Lumin designer (Wklie) is a regular on there and very helpful.

Interesting informations
I understand now ,what ´´low output  ´´ and ´´ low gain configuration ´´ are  all about.
I have never figured out that , Headphones amplifier’s selection could be that  complex.

Thanks 

@nekoaudio 
Many thanks.

I will take a look at the Bryston  BHA-1
My dealer, who sold me the Lumin also sells Bryston.
I don’t know what you mean by ´´low output ´´ mode.
I not very technical.
And yes, I prefer my system  to be all balanced.

Regards

There are several analog-only headphone amplifiers that accept XLR inputs and have 4-pin balanced XLR headphone outputs, such as those you linked to. I would recommend sticking with that approach as you've stated you want to keep the analog output of the X1.

That being said, the additional feature you probably want is some way to pass through from the headphone amp to your speaker system. As the X1 only has one pair of XLR analog outputs (unless you use RCA for a second set of outputs and switch between the two when you are switching between headphones and speakers—but I think you'd ideally want to avoid that).

Two units I'm aware of supporting what you're looking for, that also provide an exceptionally clean signal path without coloration, are the OPPO HA-1 (discontinued but can still be found) and the Bryston BHA-1. Some people prefer to get the BHA-1 in a "low output" mode for the rear outputs, as the normal output level is too high for their speaker setup.

I forgot to mention that I use my Focal Clear headphone with a 4 pin 
balanced cable.
The headphone amplifier must has this feature.
