The moment arrived to a big upgrade. I have actually a Hifiman he5le and an amplifier M^3 I will change my amplifier and my headphone. I have a budget of $2000. For this price I heasitate to buy electrostatics headphone & amp. I saw an electrostatic helmet which had a good head, the Jade of HEaudio ,I do not know if it is good but I retained it by his head
Thank you for me advised for my next purchase.
