Great customer service. I highly recommend doing business with them

My cassette player works very well! Good project.

Wide variety of items to purchase! Ordering is quick and easy but, shipping seems a little slow. Would still order from Apos again. I ordered a FiiO K11 R2R and am really enjoying the warmer sound it brings to my setup.

Very good communication and service from APOS. Only docked them one star because prices got lowered shortly after I purchased, so cost me an extra $100.

It’s my second cable and I’m happy with it

Headphone ear covers are so much more comfortable than the standard ones and they are so well,-made it feels like a factory upgrade! Regarding the sound ito my ear it does not affect the sound that much. The only downside is they do tend to get a bit warm being it is August and for log listening sessions but I assume it isn't going to be an issue in the cooler months.

The Gremlin is magic. Impressive delivery.

Topping DX 5ii is amazing! Clear amplification with nice visuals. It could use a little more power to obtain a bit more loudness, thats just my opinion.

Hassle free order and fast shipping. A+ for Apos on my order.

arrived quickly and in perfect condition, sounds wonderful,very pleased.

I saw the Snowsky Retro Nano DAC/Amp online and immediately had to have it, except I don't like paying full price. Found that Apos had it open box at a discount. Never even heard of this store but, after some research, turned out you were legit. Got my product quick, in great condition, and at a fair price. Happy customer!

Great service. I love their products.

Great unit…great price! Service was fast and convenient!

NEVER WRITE REVIEWS. SOUND IS THE CRITICAL FEATURE FOR ME. THESE OFFER CLARITY AND THE RIGHT AMOUNT OF BASS BOOST. OUT PERFORM MY NAME BRAND WIRELESS HPs AND APPLE AIRPODS PROs. SUPER PRICE POINT. MY GO TO DAILY LISTENING DEVICE. USE WITH FIIO K13 BALANCED CABLE.

Super service and great piece

Big improvement to comfort. Especially on Sennheiser headphones for me. Always got pressure on the top of my head before but now can wear much longer without any issues. Great strap Capra Audio.

Still evaluating these op-amps. But they seem to be a good improvement to the DR70n output stage stock op amps. Very nice sound into my Rotel RC-1572 MKII, Rotel RB-1582 MkII and Polk R700. Really gives the system a wide soundstage, with depth, and nice revealing crisp musical sound that is enjoyable for hours. Listening to detail, and clarity in a very musical enjoyable way. Have not tested these for dc offset, but per the spec sheet should be very low, making this a good paring to drive tube amps.

Received my new Fiio K17 R2R. The mailing was crushed on one end along with the interior box, but luckily there was no damage to the actual device. Sounds great. Good seller.

Gremlin is a great beginner audiophile product. Ray Tubes that they offer sound great.

Apos has great support and products
