replacing the volume potentiometer with a DACT21 step made the sound more cleaner, clearer.

I usually stick to the black plastic enclosed ones with 24 ohms just like Denon originals.

and ebay, only one seller

yes the chinese denon replica driver has lots of bass, sub bass and no bleed into mids and thay have consistent build quality to them the highs have some sharpness in some areas works great with unbalanced applications

Denon uses a metal mesh in front of the driver, which is also 1.5 Tesla by the way. Audio Technica uses a metal grill on many of their drivers wouldn't these count as a shield?

The Beyerdynamic Tesla drivers are grouded with an additional wire, this might be a factor in how the headphone behaves with radio waves or static electricity.

are those 1.5 tesla Beyerdynamic drivers a concern? thats 15000 gauss equivalent

I'm undecided between this 128 ohm and the 250ohm one. they look different in execution

what Beyerdynamic uses this type? 128ohm With Tesla

Question! If I buy from https://www.auneaudio-europe.com/ in EU I don't have to pay duty/custom taxes too, right?

👍

why would that be a huge risk for you? right now under shipping in EU for my order it says: Priority ( 1-3weeks, avg.2weeks )- All taxes & duties paidFree Priority ( 1-3weeks, avg.2weeks,free on $300+ )- All taxes & duties paid$25.00 Express: TNT/DHL/UPS/FEDEX etc (Exclude tax and duty)$32.00...

Probably Ohm's Laws. someone with electronics knowledge can explain better than me. you can test this yourself with the GT and Jriver player. Jriver is capable of controlling the volume digitally without bit loss, so you decrease the volume level on JRiver and increase accordingly the volume...
