Amazing compact amplifier.
Nice sound quality for the price. Very easy to use and to install. I’m very pleased with this product!
It’s great! Don’t hesitate it sounds fantastic for the price. Just know that it’s really around 30w-40w depending on ohms of speakers. The remote and excellent Bluetooth chip add to its enjoyment. I’ve been using it as a PA system for my music looping setup and tried it on some vintage KLH model 6 speakers and sounded epic. The 2 band eq on the unit is nice too.
Totally satisfied. Clean, excellent sound right from startup. Did not even require a warmup or break in.I owned an NAD 1050 D. Expensive, upwards of $700 when purchased. Never liked it. I’d owned NAD stuff before but was badgered into downsizing by my wife. So I went with that unit. Never happy with how long it took for the sound to normalize.Had fantasized about a McIntosh but knew I’d get grief for a large amp.Took a chance on this one for a little over $110.LOVE IT. TERRIFIC SOUND. Happy once again. And for a bargain price.A very good day. I’m loving it going on three weeks now. The Bluetooth works so well with Spotify, unlike the old NAD 1050.
Very nice, as advertised, great looking and works great with my bookshelf speakers!
