I have owned the ALO RX MKII for a while, and I still love them. However, they seem to not have a huge following, and is routinely being skipped over in discussions about the best, or even better, portable amps.
They sound fantastic to my hears, with a hint of emphasis on the bass. It does have a clean, impactful sound, and has a very low noise level (can’t hear anything on the W3, DBA-02 MKII or the UE TF10.
They sound, to me, better than the RSA Tomahawk (better be given the price difference), the Pico Slim, and the TTVJ Slim (later two were brief tryouts).
So why are they underappreciated in general?
