Hi Pavel,
May I ask you a favor.
I bought a set of transformers of the kind you suggested and was listed on Andrea's site.
The problem that I have is that I bought a second cheap pair from the same vendor and all came in the same box. I have no idea which ones are the more expensive Permalloy ones.
Could you point out on my attached picture if the ones
with the silver laminate core or the darker ones is the
right pair.
This would really help me.

Thank you in advance,
Klaus

Permalloy has a glossy core.

Thanks Pavel

I want to encourage all those who have the differential version of this dac to
try the cheap TPA3116 boards from China as those chips have differential inputs.
Most vendors only use them single ended but my board from Yuanjing
has the second input from the differential pair tied to ground via a ceramic cap.

As you can see on my previous picture I simply removed the ceramic caps and attached wires to the vacant pads.

This combination just makes the most analog sound I have heard from digital.
My previous combination of Xmos/AK 4490 is not even close.

The details, spacial presentation, and the organic sound is fantastic.

Klaus

The BOM shows the registers of the Nexperia manufacturer.
But the highest quality version was with the old registers AHCT595 Phillips or NXP.
Unfortunately, the old Phillips/NXP isnít equal to the new Nexperia.
