    After successfully implementing the tube-hybrid mini amplifiers Aiyima T9 and T9 Pro (and an unsuccessful test with the Nobsound B100), I was curious to give a tube-less mini amplifier a try, and my choice is the Loxjie A30, which qualifies as an all-in-one budget solution with enough inputs...

Now that I have discovered ASR I would be interested how the Kingrex performs in terms of measurements. As this product is...
