Interesting link I found in AudioAsylum about hearing

Naturally, all the audiophiles took offense to this

Thanks I rather enjoyed reading that.

Seems reasonable to me. Our senses often deceive us, but many times they are accurate. By the same token measurements can often fail for various reasons as well as tell us things that might be hard or very time consuming to determine through sensory information alone.

A balanced approach of objective measurements and proper listening tests that the author proposes seems very logical to me.

P.S. I am sure a board certified audiologist would have a good laugh at a lot of the things audiophiles say.

That article took a round about path to arrive at a conclusion more succinctly said by Richard Feynman, the Nobel Prize winning physicist.

"The first principle of scientific inquiry is that you must not fool yourself – and that you are the easiest person to fool."

Which is contrary to audiophiles 1st rule

My hearing is absolute and perfect and I'm so self aware that I can tune out all bias that might affect my hearing.

Great advice!

That should be a sig line.

I would take his comment more seriously if he hadn't been known to play bongos. That's a deal-breaker, for me.

The comment about preferring a FR that was not flat would most likely be true for all of us, if we were being truthful about it. I know I prefer a house curve from +2dB @ 20 htz ~ -2dB @ 18khtz. Which I setup as a target FR on the Dirac RC.

Have you found out if that reduction at the top is because the speakers and room combine to make it too strong and have you tried this with different speakers? It's really not a huge difference numerically, but it's definitely audible and I have heard changes like that make a system a lot more listenable because it's not as fatiguing.

It also depends on the listener's preferred volume. I like flat response toward reference volumes, but a similar house curve at a more typical speaking volume. It's best to start with a speaker having a flat response, then allow Audyssey Dynamic EQ to handle the house curve I think.

For starters, I had to compensate for tile floor and concrete walls(about all you find here). Even though I do have some wall treatments and very thick area rugs.
A difference of 4dB is quite large (every 3dB decrease is 1/2 power reduction) and +2.5dB @ 20 is certainly not a roll off.
And at the seat, there was a spike around 2000 that got cut.
It most certainly made at least a subtle difference

What can I say? He was a sub-atomic particle physicist, and you're an engineer .

That sounds like Sheldon Cooper, dumping on Wolowitz.

What most listeners prefer is an un-eq'd speaker with flat response, low distortion as a starting point that THEN responds really well to applied EQ.

I read through that post and I have to give kudo's to Chris for posting that at even his own site. A site that is unfortunately chock full of audio voodoo practitioners.

They love them some Audio Regen with zilch measurements (it's basically a 2 port, powered, USB hub).

The contention is that most USB based DAC's have an issue locking onto the incoming bit stream, therefore making the USB PHY 'work harder', introducing audible noise.

Lonnie over at Emotiva had a comment that mirrored my thoughts:

What crappy USB DAC are you using and, drum roll, where are the measurements.
