Astell&Kern Kann Ultra
Best high power portable player for demanding audiophile headphones.
This is a powerhouse for driving demanding, high-impedance headphones with pristine, balanced audio. It excels as a dedicated, high-fidelity source for serious listening sessions, but its hefty, sharp-edged design and sluggish interface make it a specialized tool rather than an everyday portable companion.
