Great!
ReplyDeleteGreat build quality.
DeleteInteresting that four mids were used instead of four bass units. The phase relationships between drivers must also be very complex. I bet it sounds good though.
ReplyDeleteYeah it sounds pretty decent.
DeleteGreat blog you have here, I really appreciate the effort!
ReplyDeleteRegarding the added resistance, I want to understand something.
When you add the resistance, does it make the impedance of the headphone raise up or does it actually make the headphones see the output impedance of the amp as a higher one?
As I understand "the 1/8 Damping factor rule" is more critical for headphones using BA but What does adding a resistor actually does regarding this rule?
Hope you can clear it.
Adding a resistor makes the headphones see the output impedance of the amplifier as if a higher one. Also, adding a resistor lowers the damping factor.

Great, thank you for your answer.
ReplyDeleteLooks like there's a pretty significant dip around 7k. Is that noticeable at all when listening?
ReplyDeleteHuman can't notice that :)
DeleteI have been reading your posts regularly about the headphones and I need to say that you are doing a fantastic job. Please keep up the great work.
