## Customer Reviews

### ⭐⭐⭐⭐⭐ Great sound for the money
*by G***Y on 27 September 2021*

Great sound quality and loads of power with this amp. I have paired with a TEAC UD-H01 Dac for my set up with PC, I can power just about anything I own, including the difficult to drive TinHiFi P1's. No problem for Sennheiser HD600's, 650's or Monolith M1060's. A passthrough for speakers with the volume control and auto cut off when plugging in headphones.Sooooo pleased with this purchase and well worth the wait for delivery from the States.

### ⭐⭐⭐⭐⭐ Headphone Amplifier and preamp. Excellent buy.
*by P***0 on 24 April 2022*
