EF500 (open-box)

​I bought the EF500 specifically to drive my Arya Organics, and the pairing is exceptional. The 4.5W balanced output provides massive headroom, delivering deep, highly textured bass control. The real standout is the R2R DAC in NOS mode—it adds a beautiful, liquid warmth that perfectly smooths out the Arya's treble peaks without sacrificing its massive soundstage. Finally, the rear ethernet port allows me to stream bit-perfect FLAC files directly from my local server, keeping my audio chain completely free of PC noise. It is the ultimate, clutter-free desktop hub for planar headphones.

Everything was fine, the EF500 sounds perfect! Great discount! thank you

Very good sound and value. Absolutely recommended.

Excellent for the price and a great pairing with the HE1000 stealth.

great sound, but device is a little noisy, overall very good
