Asking with no snark...
Have you ever tried these comparisons with basic controls (unsighted and level matched)?
I had to hear it for myself too...
It's easier to let go, when/if you can hear it for yourself, or rather NOT hear it in my case.
A while back, I found this image on the internet. I also found a video of a Yamaha engineer tuning an amp for the UK market. Did a little research, turns out Europeans does not share the same taste in sound as North Americans. North Americans seems to have a cultural preference for "warm" sound (what ever the hell "warm" means). And that is not to the taste of Europeans, so Yamaha "tune" there amps for the European market.
Assuming this is true, 1) I wonder what the heck are they tuning to tune the sound 2) can measurements alone be enough to determine if one likes the amp or not? If an amp is "tuned" and the measurements specs are the same for all regions, then is measurements alone enough to determine ahead of time if one will like the sound or not without an audition?
I don't know, I don't have the answers, but I want to ask the question and open this up for discussion.
EDIT: Here is the video of the amp tuning done by Yamaha
I've checked the user manual for the US and UK model of the A-S1100, same exact identical specs. But yet, the UK version has been "tuned" and assuming it sounds different after such turning. So why is such difference in sound not reflected on the specs? Does spec alone measure the "sound signature?" Can I trust ASR's recommendation that, one does not need to audition an amp, they can just buy it by looking at the measurements and specs? (Not an insult, a honest question)
Now I show this video and picture to a diehard pure objectivist in the past (The same type who said to me, there is absolutely no need to audition any amps, all you need to do is look at the measurements, there is no such thing as "sound signature."), he simply dismissed the picture and video as marketing gimmick.
MORE EDIT: I did a little research on this guy, Taro Morii, who was doing the tuning on this video. I found
this, patent filings, so clearly, he is not a marketing guy, he's a legit engineer at Yamaha.
I also attached the user manual of the US and UK version of the Yamaha A-S1100, pretty much same exact measurements and spec, but yet, the UK version was "tuned." So are they concluding that measurements and spec can't measure everything? What the hell did they "tuned" to change the sound without changing the specs and possibly measurements exacty???
