AK45 Pro Stereo Amplifier Home Audio, Stereo Receivers with Bluetooth 5.0,Max 400W, 2.0 Channel Audio Receiver for Home Theater Speakers w/USB/SD/RCA/2 MIC in for Karaok

I bought a digital turntable and powered speakers. the sound was very tinny. Bought this Amp and a set of passive bookshelf speakers. Huge improvement. very good value.

I got this to use with my computer to amplify a pair of 6-inch 2-way speakers for better quality than you can get with the typical dinky PC speakers. Won't win any fancy audiophile awards, but they work just fine for basic listening for streaming videos and music. Can't really beat it for the price.

Nice little unit. I got for fm radio, but doesnt pick up good. The antennae really does not deliver...sorta,sucks

I use it to drive a 6 living room speaker system consisting of 2- Altec Lansing, 2- Sony and 2- Pioneer CS-C9000 all encased in their own wooden cabinet driven by Apple Music on my Mac M1 desktop. Movie soundtracks from John Williams, Hans Zimmer, Barry Goldsmith and Bernstein come alive in the highest fidelity. Exceptional sound from a cheap little remote controlled amplifier, with Bluetooth, FM Radio and USB inputs including a microphone input.

This is a great amplifier. Well worth the price. Great quality output also thru high quality speakers.

Very good sound quality and power! Bluetooth function works fantastic. It’s a winner

The AK 45 Pro series amp is a little beast. My office head unit died, I nearly clutched my chest like a Victorian widow, and after a quick hunt I rolled the dice on this thing. Surprise: it sounds clean. It also happily pushes about eight speakers in my office, which is great until you realize it will also try to evict you from the building. I had to turn it down because it was treating my workspace like a tailgate. Hookup is almost insultingly easy. Operation is simple enough that even a sleep-deprived adult with coffee-shaky hands can manage it. I’ve only had it a month and a half, and I’m already eyeing a second one for the shop out at the ranch. For the price, this is a steal. Bluetooth is a nice “yes please” extra. Try it. If you hate it, you might just be the person who also complains that pizza is too pizza.

Sounds great! Using it with my media server PC. 2 issues I see so far - 1) documentation on device functionality and and interaction with the remote control. I have a Visio TV that I use as the display monitor. When I select the EQ button on the remote, the TV changes input source. Should have a unique code that doesn't conflict with other devices. Also, if I turn the TV off and use the remote to change the EQ (which isn't really documented well in the user manual), nothing happens. I don't see any EQ presets. 2) It seems strange to me that there is functionality within the remote that can't be accessed from the device front panel. Maybe it's just me. You can use the remote to turn the unit on and off if you leave the physical power switch on. However, the lighted volume dial stays on regardless of the function on/off you select on the remote. Makes me wonder if the unit is really off or just the digital display is off. So, I physically turn off the display. Again, I like the sound it produces - very crisp and clear over all frequency ranges. I also like the ability to play a USB driver. However, they have a repeat function and a forward or backward function for the tracks on the USB driver but what I would have liked to see was a shuffle function. Oh well, the price was good and performance is OK so far.
