Apos

Apos is a great company and I highly recommend them. They have great customer service team and they respond quickly and offer a great exchange policy. I finally found my perfect headphone setup. Thank you!

Very good

Fast shipping and well packaged

I was shopping for a small desktop headphone DAC/amplifier for my home office. I was shocked by how many choices were available in the marketplace. A friend had purchased from Apos and steered me there. I engaged with Peter, the customer care agent. He was incredibly responsive, patient, and helpful in guiding me to the best choice for my needs. I purchased the unit and it arrived on time and in perfect condition. I couldn’t be happier.

Love my 5u4s! Ordering was easy, shipping was good, and the tubes sound AND look great! These were recommended to me for Cayin HA-6A a mk2 and I'm very happy with them.
