I find ASR to be unreliable. Why? Because it focuses on measurements only and they do not listen (well, now they do a bit more but still). Example. They sing the praises of the Topping D90. Never listened to it. They reviewed other products that measure less than the D90 say it cannot be recommended. Never listed to it. I’ve had those products in my system and found that the D90 ain’t great sounding but it is good for the money. This is not about personal taste but rather it’s about parameters such as detail, sound stage and clarity. I love my Benchmark AHB2 to bits, ASR says it’s totally amazing (based on measurements). But there are other power amps which do not measure as well yet gives me a lot more listening enjoyment. Then it’s known that Amir says listening at something like 90dB is not loud. Loud for him is quite a bit more than that. What’s his hearing like? So even when I question ASR, I do have points to try back up my apprehension about them.
