So kindly guide me to any specification sheet of any amplifier that shows based on inter channel phase and level correlation:
Manufacturers don't put it on a spec sheet, but reviewers do measure it. For example, look at the first graph in
this Stereophile Magazine review and you'll notice that the left and right channel have almost half a decibel of level difference. So if you're listening vinyl on this Marantz integrated amp, the image is going to be shifted a little to the left (all things being equal).
The alternative is to simply accept someone's subjective view, because you believe that parts of an electronic circuit in a box (integrated amp) cannot be measured or quantified. So if someone subjectively experienced better imaging, then you have to accept it. If that same person experience the Loch Ness monster...
When I said these cant be measured, I did not say absolutely. I meant in the context of this thread where specs. like cross talk, THD are being bandied about.
You have to work with what you have in the real world, and those are the specs that manufacturers provide. So if someone claims that shelf A is stronger than shelf B, but shelf B is spec'd to hold three times the weight of shelf A, then that claim cannot be supported. Likewise, if someone says that stereo amps have better sound quality than AV receivers, yet none of the specs we have to work with demonstrate that, then there is nothing to support that claim. Unless you're willing to accept it on faith.
BTW are you not contradicting yourself by saying that these cant be measured and...
Yes, I should have phrased that better by pointing out most of those were items are typically not on a spec sheet, excepting "dynamisn" (assuming it meant dynamic range).
In-fact recently when I was auditioning the Harbeth SHl5, the dealer stated that in his room the soundstage depth was measured at upto 8' behind the speaker baffle. I don't recall seeing that specification in the Harbeth manual or any of the accompanying equipment manuals.
Soundstage depth is function of several things: room acoustics, speakers, source material, your hearing, etc. (doors666 got the priorities right). How would Harbeth know the specifics of your dealer's showroom, let alone what he heard?
I am not trying to disprove you maybe you are right and all the thousands of $ I spent on my stereo equipment was in vain:sad: - I should simply buy the best multichannel receiver there is
You should buy what makes you happy. I don't understand why you are making this so personal. This thread isn't about you or your equipment (nor me and my gear) but helping the thread started find something to drive his speakers. Which is why I based my recommendation on objective capabilities/qualities, so he wouldn't have to take my word for it (i.e., rely solely on my subjective opinion, biased by my personal preferences).
personal listening bias (can we measure & quantify that?)
Subjective listening results minus blind listening results equals bias error, typically expressed as a statistical deviation. However, if you're more comfortable believing that listening bias is an immeasurable intangible, then ignore the previous sentence.
BTW the Audyssey MultEQ and Dynamic Eq. implementation on my Denon 2310 is pure crap. I used it to balance channels and found them significantly off, and redid everything manually (probably because the mike they provided is some dollar store special and because they have to stuff some much into one box for the given price compromising the sound). Found the same thing on a friend's 4310 as well. Maybe Onkyo implements this better than Denon.
They should be the same implementation (doubt Onkyo gets a special version of Audyssey that Denon can't have). Guess I've never had the bad luck with Audyssey that you've experienced, nor have others in my local HT group. Channel balances are typically fine, as are distances (including latency of other devices in the signal path). The main complaint is too little bass (Audyssey's target curve is measured flat, when it should be perceptual flat). But raising the subwoofer level or bass level fixes that. If it didn't yield a net positive most of the time, then it wouldn't have caught on with several manufacturers.
BTW, it may be worth downloading the Audyssey set-up guide at the end of
this post and giving it one more try.
