Loxjie P20 Balanced Tube Hybrid Amp for Under $100

I just picked up this balanced tube hybrid for no other reason besides the fact that its $85 on Amazon with Prime Delivery. It’s a small and compact. Sounds alright.

Tubes probably need to burn-in for a bit to open up, so will report some impressions later. It has balanced XLR and 1/4 SE out, and XLR and RCA inputs with a digital volume controller which also acts as the power switch and input/output switch. No EMI noise at all, which is wonderful! Not even when I put my phone right next to it.

Also the packaging/box looks like a Massdrop box.

Manufacturer's Description:

P20 is Loxjie’s first full balance tube amplifier headphone power amplifier! It use the military grade 6N3 tube.

Plus the well-designed and calibrated amplifier circuit! Let the amplifier have lower distortion under the premise of ensuring"Tube Style"!

And the P20 also has true balanced inputs and outputs!

This can maximize the performance of the headphones!

  1. Bought a Loxjie P20 a few weeks back and continue to marvel at how
    nice this little headphone amp is. The single ended outputs
    are far too low powered for any headphone over 16 ohms or so.

    The balanced outputs are where the P20 really shines. Fit and finish
    are also extraordinary for a tube headphone amplifier costing less than $100.

    Great value!

  2. Does anyone know the output impedance for balanced and unbalanced of the p20?
