Excellent and fast

Zander Quigley

Good thing, it remains to wait for good headphones, now I tested it on iPhone Wired, the difference in bass and volume is twice better than on the built-in sound card.

Providenci Maggio

Arrived in perfect condition and before the scheduled date, they were to arrive on the 31st and arrived on the 20th!

Jerad Lakin

I am a music lover with 50 years of experience, I've chosen this DAC for my daughter after studying the reviews, but I was very surprised by such a great sound as from a DAC for $2000 - I did not expect it.
I'm also waiting for the FX AUDIO DAC-X6MKII Bluetooth 5.0 from this store.

Stewart Daugherty

Delivers what you promise, I have no experience with other DACs but the confidence is in the recommendation of the Leonardo of the mind the headphone channel.
