@jtgofish Sadly, I can't even say that ASR does a decent job at covering low budget amplifiers. ASR just does their usual benchmarking and you're lucky if some member does a comparison between an Infineon chip amp and a Texas Instruments chip amp for example. So you'll be even more confused about amps from reading the ASR forums. So intuitively you'll want to buy the latest offerings from SMSL, Topping or Sabaj. Which one is better? Nobody can give you a straight answer. Some of these amps approach 300€. And for that money you could buy a Cambridge Audio AXA25 (new). But ASR does a poor job at covering budget AB amplifiers. So nobody can tell you whether you should buy a cheap AB amp or class D chip amp. You only have a "SINAD" score to compare the amps.
