SMSL HO100 Review (Headphone Amp)
This is a review and detailed measurements of the SMSL HO100 balanced (input) stereo headphone amplifier.
Conclusions
The SMSL HO100 delivers on three of my favorite features: balanced input, included AC adapter and low cost. Distortion and noise performance are excellent landing near the top of the class at any price. Power output though is good to excellent depending on your headphone impedance, leaving room for pricier offerings from SMSL and others. The only odd thing in the measurements is the muting at subsonic frequencies (which I could not force with music content with very deep bass).
I am happy to give a recommendation to SMSL HO100.
