@amir_asr Either you are or are not the owner of ASR. Either way, my conclusion is based on listening results after measurement (if it can be measured-the CD trimmer can measure some characteristics prior to and post trimming by listening to the CD). Since I do not rely on measurements only, I (and all of my many music loving friends) use my listening skills to determine if audio equipment sounds more or less to my liking. Measurements can be very deceiving both in what is and what is not measured as well as the potential synergy with other equipment and listening room.
The best test of audio equipment is to place it in the room and with the equipment it is to be used with. Aside from that, measurements and physical inspection of audio equipment can provide a basis for comparison and evaluation (such as will it more or less likely to fail in use). It goes without comment that different power ratings of amps and bass capabilities of speakers vary by design and parts quality which can result in lower or higher cost to manufacture. Unfortunately, just as with so many other products (non-audio) on the market, you don't always receive what one pays for. There are many shoddy expensive goods in many product categories. That does not mean everything deemed "too" expensive is bad.
ASR "militia" cannot differentiate the difference between biographical summary of one’s music expertise versus self-aggrandizement I am no more important than any other audiophile; however, music experience as an amateur recording engineer in major orchestral halls of well over 250 recordings and for the Erich Zeisl (brother in law of Schoenberg) centenary collection of 11 CDs for Vienna, UCLA and USC establish some credentials that my opinion in how vocal, chamber and orchestral music can (not should) sound is evident. I do not have a "golden ear." I just have a lifetime of experience performing and recording/mastering music.
When I conclude that each individual should not rely on measurements only, I am asserting that each piece of equipment should be tested for it’s musical value (not economic) in a specific room with specific equipment. ASR members laugh at anything outside of their sphere of experience and make derogatory remarks of someone’s character if they disagree with neutral statements concerning equipment or experience. If that is you Amir, owner of ASR, you know this to be true.
