very good
Made my Hi Res Headphones Philips X2HR at 30 ohm impedance sound much lower. Do not know why it did not work as I taught.
200 ohm impedance connected to my Philips X2HR (30 ohm) just made the sound from the headphones very low even if I turned it to Maximum volume. I tried with a LG V30 which is capable of up to 600 ohm impedance.. Probably should have chosen 75 ohm... Hope for better luck next time.
