Premium P1 Bluetooth 5.0 Vacuum Tube Preamplifier: Enhance Your Audio Experience with Hi-Fi Valve Headphone Amplification, Wireless Connectivity, USB DAC, and APTX-HD Support Review

Pros: Some nice features like bass and treble controls, selectable Bluetooth, USB or AUX inputs and a smooth volume control. (Yes, I know most serious audiophiles will only use the digital input, not BT or Aux.) Cons: Depending on what headphones are plugged into this amp, background hiss can be noticeable and a bit annoying. When using my Andromedas or Solaris IEMs, the noise is very noticeable. When using my cheap Sony or JVC headphones, the noise is barely noticeable. (I have other…

This only arrived an hour ago so this is based on my first impressions. I'm impressed to say the least. Great DAC/headphone amp. Very well done. There is nothing to complain about in terms of processing quality. In this price range, you never know what you're going to get. Bass and treble controls really add to the P1's versatility. I suspect they are analog. I don't really notice a change in sound quality when they're set flat and then turned on and removed from the signal path. But the…

Now on to the physical aspects, I really liked this design, it's very beautiful and brightens up my office. The power button has a red power indicator. It also has three switches to select the handset's LED color (blue…

Are you saying that for $100 I could fix all the sound quality problems on my PC? clearly inferior to the analogue. I know it's mostly a matter of taste, so that's my taste. I really like the sound of R2R and vinyl in music, it has a warmth and depth that fills the room. I always felt that PC sound was missing. I was skeptical about the purchase but decided to take a chance. I ended up spending over $100 on software and other products to try to make my music sound right. I was a big user of…

It's been over a year and I still love it. I still use this little amp and love it. I was initially disappointed with the USB input as there was a lot of noise when connecting to a desktop computer. This amp lacks an optical input which would make it almost perfect. But last summer I hooked up all of our computers to a panamax surge protector/line cleaner to protect them during a lightning storm (yes, we have extension cords everywhere). It was some time after the cheap optical DAC died and I…
