Impressive performance in a small package

I was skeptical about both the performance and sound quality of this amp given its relative cost and small size. Both problems are not problems. I hooked up a turntable to a preamp and this amp really delivers both volume and fidelity. I've hooked up a set of JBL ES 30 speakers to it and it drives them with no problem. There's a small toggle switch on the back to switch the input from RCA to BT, which might be more intuitive from the front, but the functionality is fine. Would buy again.

Cons
  • Good overall but...

Nobsound A2: Flat, uninteresting sound, weak bass extension. not for listening to HIFI music.

I've long bought this amp hoping that the extra power would drive my ELAC Unifi UB5 better than my current fosi DA 2120c, but it's a huge disappointment. Nobsound A2 is NOT a HIFI device. very flat sound, poor soundstage, no spread and clarity in the mids, bass is cut off, high frequencies are steely and thin. VERY DISAPPOINTING SOUND. Bluetooth works well, handles and construction are fine. It's just not a serious device for listening to music. I just wish my Fosi had a little more power, itโ€ฆ

Amazing sound quality for the price. Bye.

I was doing a backup phono stage setup and replacing an old Denon 50w stereo receiver when COVID hit and I got fired. Due to limited finances I had to look for a cheaper power amplifier. Enter nobsound. At $90 I couldn't go wrong. After a 10 minute setup, I went to The Beatles White Album and immediately heard the difference. Crisp, clean, with good, tight bass. Also enough power. I played almost all my records and the sound was better than my old Denon day and night. I almost forgot this thing

Exactly what I was looking for

I was looking for a small stereo that could drive my 80 RMS speakers and this one almost nailed it. Knowing that 160 watts is peak, the RMS is usually half that, so 80 RMS seemed like a perfect fit. Knowing the limitations of my speakers, this amp can deliver 70 RMS with the power on. One weird thing I noticed is that Bluetooth volume is better than with RCA, which is usually the other way around. Bluetooth connects quickly and sounds great if you're listening from a distance and don't careโ€ฆ

Cons
  • Update Availability

Good amp, especially for the price.

Amplifier works great straight out of the box. The PSU isn't great, some very faint hissing at 0% volume, most likely from the PSU (but honestly doesn't matter and can't be heard when playing music). I had an unswitched DC power supply on the go, I'll update the review when I'm done. With my 100 watt speakers per channel, this thing goes from quiet to super loud instantly. The only problem I have with this amp is the volume potentiometer. The high and low frequency potentiometers are nice andโ€ฆ

Cons
  • No paint required

I like the sound though.

This is a great mini amp with amazing sound, which I believe is due to the TDA7498E chip, which delivers high power and clear, undistorted stereo sound. The CSR64215 Bluetooth chip really helps achieve faster and more stable transmission. I compared this amp to the Fosi BT20A and the difference in performance was significant. The Fosi amp was much smaller in size and weight with the same build quality. Fosi's power supply is 24V 4.5A while Nobsound uses 35V 5.0A for 80W per channel for my 8 ohm

Cons
  • Not sure

Just what I wanted for home audio

Nobsound A2 160wx160w Bluetooth Mini Amplifier. I've only used the amp for 1 hour so I don't know how well it will hold up over time. Everything worked great out of the box. I have speakers that are over 30 years old and wanted to see if they still work. In fact, they sound the same today as they did 30 years ago. I have a Klipsch sw8-II powered subwoofer and 2 Polk Audio 5jr speakers. I only intend to listen to music from my phone via bluetooth and I found it sounded really good (I'm not aโ€ฆ

Cons
  • Low repairability

Much better performance/sound compared to 100w x 2 mini amps

I work A LOT with small class D mini amps. I have bought and used several. I found Nobsound gear better than Fosi, Breeze Audio etc. So I was VERY excited to see Nobsound start offering their 160W x 2 BT amps on Revain. I had to try them. A NOTICE! These amps are not 160w x 2. These amps have been professionally tested on dyno test equipment. They are around 65-70 watts (RMS) per channel. However quite thick. I'm using one with a Skar Audio 15" DIY passive subwoofer. Subwoofer 4 ohms + 4 ohmsโ€ฆ

Cons
  • Definitely bad product
