I'm not a hifi nerd, but I definitely don't like all-in-ones and bluetooth speakers around the house. To my ears, this is great.My first dip into these tiny Chinese no-name amps, I did do a bit of research and Aiyima seemed to be one of the better brands. I needed optical since my system is based off a Wiim mini (amazing device) for Airplay. Not many of the cheap amps had optical, this does.To give a comparison, I was coming from a (massive) Panasonic SA XR 700 amplifier, one of the early big-name amps and one which people still rate highly. I could never love the sound, it was so clinical, so detailed it could be exhausting. I realise that's a plus for some, what I love about this Aiyima D03 is it has a pleasant warmth to it.I don't care about looks with something this tiny, but it looks fine, the remote's fine, I never use it since I use my iPhone with the wiim. It has bass and treble controls. One of the best things is it's so tiny it sits on top of my speaker (Q Acoustics 3030i, works great with them), and barely uses any power at all on standby. A plus in these times.

Was looking for a small form amplifier to hook up to my TV via optical port to drive a couple of large speakers. I had a much cheaper Nobsound unit doing the same job but it didn't have a remote control feature or the optical input.This amplifier is well up to the job and sounds and looks great. The display is quite small so hard to read this at a distance, but can't really expect it to be any bigger on such a small unit.I did experience an issue with the remote control whereby the volume buttons (particularly volume down) were working intermittently or not at all. I contacted AIYIMA via the Amazon product page and received a response right away. They shipped me a replacement remote control which on receipt confirmed that the original remote was faulty.From a customer service point of view, I was really pleased with the support recieved and hadn't been let in a position whereby I'd have had to return the product for refund or needing a full replacement.Thanks team AIYIMA 😁

lovely little compact Amp with plenty of connection options, mainly bought for Bluetooth for my projector and TV sound, I'm happy with it, its running an old pair of mission 782's with no problems, and a mk acoustic pro sub

Fab little amp with plenty of power, bought for use in a 4.5m x 3m gazebo for a wedding. Used with B&W 602 speakers.Plenty of power and punch, had been worried about depth of sound and bass level, but this little amp was brilliant and not used at anywhere near full volume.Bluetooth connection was straightforward as was cable provided for laptop.Did exactly what I needed it to do and will be used for further outdoor parties/events.

Film and music great sound reproduction great clarity and stereo imaging along with superlow bass excellent product.
