We cant' tell from that information. there is nothing telling us how they are wired.
@fadetoblackbs This one on Amazon UK has the correct Pseudo balanced wiring. Obviously you'd need two for stereo connections.

I got this information from the supplier - as far as I understand it is the right way:

„2549 consists of 2 wires plus shield.
The way we normally connect these cables (& we don't have any issues) is the following:

XLR side:
Wire No1 (Hot): PIN 2 of XLR
Wire No2 (Cold): PIN 3 of XLR
Shield: Pin 1 of XLR

RCA side:
Wire no1 (Hot): Signal of RCA
Wire no2 (Cold) plus Shield: Joined together at the shield of RCA“

Yes, that looks fine - and matches the diagram in my post above.
 
If I understand Amirs statement on the very first post correctly, this means I should aim to use the lowest gain setting on this amp for best results?
"You can see the benefit of low gain in am amplifier for best noise performance especially since the dynamic range of the DAC improves as well with higher output."

Yes - use the lowest amp gain that will allow you to drive the amp to the maximum volume you need.
 
4 gain settings and load independent it would make a fun amp to on very hard to drive headphones like the Tungsten
 
I have ordered this unit. Can’t wait to try it out.

Created an account to let other users know that amp does not ship with a power chord. So you’ll have to source that and include in overall costs if considering other options.

just to avoid any frowns on Christmas morning when a lucky person unwraps their new amp but can’t use it until a power chord is sourced.

Great forum and review. Glad to be here.
 
The infamous "Black Fraud" as we say here... :facepalm:

Hello, first post

I was watching Blade Runner 2049 quite loud and the Apollon just shut off. So did my receiver. This has not happened with my other amplifier.

I had to pull the power chord from the apollon and put it back in. Then it started again.

Is this some kind of clipping protection?

In your email you did not mention that your receiver turned off as well. Are you triggering the on/off of the Apollon with your receiver?

No Matias, we are not engaging in any “Black Fraud.” All our models are currently discounted, and the prices remain unchanged across the entire range, except for the ST models. The price adjustment for the ST models was necessary due to increased costs of specific components and materials.

No, i do not use the trigger on/off in my receiver or with the Apollon. I have watched other movies at the same volume and this has not happened then. I was just courios to why it happened and if theres an explanation.

With my other amplifier this has never happened, not even with Blade Runner 2049.

I really like the Apollon :)
