I wanted to purchase this a few years ago but couldn't decide what speakers. I found a pair of Realistic Minimus 7 for $20 on Facebook Market Plus in mint condition. After about an hour of playing, I was blown away and the sound warmed up. Looking for a wonderful amp for near listing field.I would recommend this amazing little amp

I had some pretty decent SONY speakers from a shelf system from the 90's - the base unit went kapupt (kept spitting out cdrom tray) but I kept the speakers! Went looking to see if there was a better alternative and came across this beauty. Now I have this connected to an iPad and it's my music station.

I was amazed by the quality of sound in this mini tube amplifier. I have been gradually start using it at low volume for about 30 hours now and gradually breaking it to half volume and I am truly satisfied in its performance - sound getting better as per vacuum tube amplifier characteristics. It recommendable for others!

4.0 out of 5 stars Wow!
Reviewed in Canada on November 23, 2023

Took a chance on this when my giant home receiver finally died. Running our Apple TV into it and playing through a pair of Klipsch tower speakers. Great for movies and music alike.
Fills our very large living space very well with clean and warm sound. The AppleTV remote adapted to it as well for volume control.
I actually had to install an attenuator, as it didn’t get quiet enough for conversation BG if we were too close to the speakers. Has a quirk where it sometimes doesn’t want to wake up after muting with the AppleTV remote, but it works again after turning it off and on again with the supplied remote or on the actual amp.
I’d recommend and would consider another if I needed it in a different situation.

3.0 out of 5 stars Good sound, misadvertised
Reviewed in Canada on November 10, 2023

Sound from this amp is 7 out of 10 where my 10 is audiolab 6000a. First thing I did is I upgraded tubes to GE ones. They become warmer but not sure if better. I guess it's personal preference thing. All in all they worth the price but I had to return as my speakers require at least 70 watts to sound their best and this amp barely makes 55 wpc, while advertising 100 wpc. Upon research I found out you can upgrade power supply to get more watts out of it but this upgrade moves this amp to another price leauge where you'll find better options

5.0 out of 5 stars I loved it, for the few weeks it worked. (Updated)
Reviewed in the United States on March 6, 2023
Verified Purchase
Edit: Changing from 2 to 5 stars. It was the ac adapter that died, not the unit.

I bought this to redo my PC sound setup for music production and also incorporate my tv into the mix with the optical in.

Everything went as planned. It sounds great, but I'm coming from a smsl setup so it didn't blow me away or anything. But for the price and additional inputs and the cool aesthetics I was super happy. The remote being a huge huge plus.

After a few weeks I watch some YouTube videos after waking up. Everything is great. Go to Hogwarts for a bit. Great.

I leave for the day and when I come home it just won't turn on. Nada. Completely dead.

I don't smell any magic smoke. Luckily I'm within my return time with Amazon so I don't have to deal with the manufacturer. I'll update this review when my new unit arrives tomorrow.

The only thing that I don't like about this amp is what everyone else complains about. It'll go into standby if there is no sound for several seconds. I can deal with that. I don't see what everyone else is talking about with db scale not doing anything. It doesn't on low volume but it does when you turn it up. That's understandable to me.

More importantly to me is that the volume goes up and down in notches. So the very lowest volume is still louder than I would like watching stuff at night when I fall asleep. That may just be the way optical comes out of my tv, I'm not sure yet.

For the price, aesthetics and integrated DAC, I'm not sure it can be beat.

It is amazing what a nice sound this little thing can provide. Especially I like warmth of the sound (kind of softness) produced by tubes. Pair it with Polk's speakers (like I did) and you would just "bath" in music all day long.

5.0 out of 5 stars Amazing Output for a little guy
Reviewed in the United States on May 1, 2024
Verified Purchase
I ordered this without much prior knowledge and coming off a failed experiment with a similar item from a lessor brand, so to say I was apprehensive is an understatement. The box arrived and the unit was well packaged, very solid feeling, and amazingly small for such claimed output. Quickly hooked it up to some small Polk speakers I have and WOW, this little box kicks out some power. No distortion at any level, just clean, crisp high and lows that you can feel down the street! WOW is literally all I could say after hearing this little box sing. Do not hesitate to buy this, you will not be disappointed!
