Due to circumstances, I regret that I could not go.
Speaking of headphones, headphone amps. Therefore, I decided to go to the
HDA-5210MK3 from BAKOON PRODUCTS.

Although not well known in Japan, this headphone amplifier is quite famous overseas, both in the East and West.
Enjoy the overwhelming sound of it's current output!
