I’m looking to sell my QA390LE. It works great for most IEMs, I don’t recommend audio64 or campfire (most models) but everything else has no issues with noise floor. I really enjoyed the combo with Aroma Fei Wan which is quite sensitive.

This bad boy can drive tungsten DS to at least 90% of the way from the best I’ve heard it(plenty of volume and play on volume knob) But unfortunately I sold the tungsten and most of my gear so here we are. Shouldn’t have any issues running any headphone through the qa390le offering plenty of wattage, gain and voltage.

It’s a swiss Army knife and a device I’d recommend someone who wants a reference source when auditioning headphones or amps with flexibility to pick up and go. Offering a bypass to it’s battery, can be used with direct external power and of course is battery powered lasting around 10 hours on a charge. if anyone has any questions on specifics about the qa390le don’t hesitate to Direct message. I’m asking $1025 shipped.
