Universal Preamplifier/Headphone Amplifier/Media Player

Using this now to play music files through TF card slot and listen to headphones, but I plan to connect a stereo receiver in the near future and run several different tubes through them. . It has a remote control and makes it easy to adjust the volume, input, etc. The sound quality is pretty good and I like that the op amp is in the jack [I have some more expensive ones, I will try in the future] Overall a good device and cheap price.

Pros
  • Stylish and modern design
Cons
  • Negative impression

Excellent tube preamp

This is a fantastic sounding preamp. I am very happy with this headphone amp and can use it as an auxiliary input for my main amp and it sounds good, I upgraded the tubes and it really improved things, but it used to sound great with the tubes. This device looks good and is very versatile, the only thing to note is that the SD card slot is not perfectly aligned and it is possible to insert SD cards, the card can fall into the device. I also wish it had a master volume control rather than just a

Pros
  • Stable test results
Cons
  • unreliable

Sounds good! suitable for amplifier

I was skeptical to buy without reviews but I tried. Sounds really good and the Bluetooth connection to my iPhone is solid. It's a bit noisy/static/crackling when it's first turned on for a minute or so, but it might be a weak tube thing, but after it's warmed up it gets solid. If it lasts, I'll buy better quality whistles. The only negative, and I knew this in advance, is the lack of a volume control, but the buttons and remote control work well, I hope they hold up. I checked several MP3s on a

Pros
  • delivery was very fast
Cons
  • compatibility

I really wanted to like this tube preamp.

Bluetooth connects easily. The signal to noise ratio was excellent. The sound quality was very good but kept cutting out when people were talking, I couldn't tell from the music but it was likely. I have the AIYIMA Tube T9 version and I have the same problems as this one. My biggest issue with both is using the RCA inputs, if the left input is not connected the audio on the right will cut out. I spent hours of my time trying to figure this out on AIYIMA thinking it was a soldering issue or…

Pros
  • GOLS certified
Cons
  • Only available in black

Don't buy this! Speaker covers are a good investment

The volume button on the remote either did nothing or reached 11 on a click bluetooth needed 1 try once at least 10 tries on average once 2 hours too , then with the remote the problems must be basically in front of the box because when the bluetooth decided to to connect the volume can be reduced or fully increased, can not say there are no volume meters. Luckily I bought new resistors with this thing and hopefully they did the job. On the other hand, fuel delivered on Christmas Eve for the…

Pros
  • Easy installation
Cons
  • Other interesting options are available.

blown away! on Home Audio

So I bought this to test before adding it to my main setup in my listening room. Not new to audiophilia, but new to tube preamps/amps. I ran it through a Fosi Audio Class D TPA3116 mini amp using standard tubes for 3 months and always thought it had body, but the highs have definitely died down. Sonically, it was boring, to say the least. Enter the world of high-quality tube preamps! I bought a set of GE JAN 5654W bulbs here and fuck it! So first I had to spread each pin with a steak knife to…
