Well built ; Extensive connectivity ; Big, weighty sound ; Refined ; Forgiving with lesser quality recordings

Lacks the level of drive and dynamism found in the best

Worth auditioning at this price, but it needs to deliver more energy and excitement for the full five

OPPO continues to amaze everyone with their products. The is a legend. Now the are startling us all, and the HA-1 . . . well, all I can say is if OPPO were a publicly traded stock, I would be sad that I couldn’t buy any, since I review their products.

The HA-1 is beautifully built ; The HA-1 supports all current digital formats ; The HA-1's sonic character doesn't change as the volume goes up ; The HA-1 can power even hard-to-drive headphones to satisfying volume levels

The line output does not automatically mute when a headphone is plugged in ; The remote volume control is over-sensitive ; The Class-A amplifier section runs warm and requires adequate ventilation ; With highly sensitive earphones, the HA-1 may produce...

When audiophiles use the term "high end," they are usually referring to a component's performance AND its price. Ever since The Absolute Sound's Harry Pearson initiated the "I have the best toys, and you don't" gambit, high-performance audio gear has...

Fantastisk nøytral klangkarakter som passer en rekke high-end hodetelefoner, og mange tilkoblingsmuligheter. Blant annet Bluetooth

Tross enestående lyd og fleksibiliteten til HA-1, er det et kostbart produkt som kan gjøre et kraftig innhugg i budsjettet til entusiastene

Prisen er den eneste ulempen med HA-1. Den er ikke billig, men så får man upåklagelig lydkvalitet, fra det vi opplever som en av de mest anvendelige hodetelefonforsterkerne i dagens marked. Entusiaster må definitivt ha Oppo-forsterkeren på listen over...

Ich hatte außerordentlich viel Spaß mit dem Paket von Oppo. Was auch an den umfangreichen Features des HA-1 liegt, insbesondere im Zusammenhang mit der persönlichen Ausrichtung meiner privaten HiFi-Anlage. Die Möglichkeiten, ihn als Zentrum einer...

Fantastiskt neutral klangkaraktär som passar en rad highend-hörlurar. Många anslutningar, bland annat Bluetooth.

Trots enastående ljud och flexibilitet är HA-1 en kostsam produkt som kan göra en rejäl buckla i entusiasternas budgetar.

No lack of inputs, including Bluetooth; Headphone amp is good all-round with plenty of power; Functionality is well thought-out

Mute function for the pre-amp output only accessible on the remote. Knob feel for the volume is terrible. Display text is hard to read at a distance
