I have couple questions to “ASR Tests Originator”:
1: Can you please describe your measurement equipment' employed at ASR LAB? I assume tester is calibrated, maintained, and upgraded periodically, - correct?
- are you doing your measurements in Faraday Cage?
-what cabling, loading, power, additional filters, shielding, etc are used for ASR tests? ..and why do you think your test setup is good to represent average user?
2: How do you select units for tests? Do you receive devices from manufacturers, or do you obtain those randomly?
- sometimes manufacturers prefer to send “good units” to third party test LAB to produce “excellent reviews”, while most of manufactured units of the same model are "so-so". I haven’t seen two analog sound units, including speakers, amplifiers, pre/eq/etc of the same model/brand with the same test results in my life!
