Mr Carr

Very enlightening indeed. Of course i made the insensitive remark half joking, but would never have thought that an experienced listener can be easily misled by visual and other non-related cues. Having heard many high-end commercial products, some highly praised in the press, i have usually felt disappointed rather than exalted after a first hand experience. Still, my observations on other's reactions is very limited indeed. Again, an excellent post and another one to enter my collection of JCarr's posts (my favourite is the story about the Riken resistors and cheap opamps in the Sony DAC).

Default Soft vs hard

I didn't read the 150 or so post on this thread and I don't drop in to actually discuss the subject but I have a view point that could explain the difference in sound of different pads.

The idea is that different pads will stress the chip waffer differently, this is, a soft pad will stress more the waffer than a hard one. Also the heatsink surface flatness where you mount the chip will also play it's roll on this. All this is more evident when you use a simple screw to press the chip against the pad/heatsink.

On the same idea the tork you applay to the screw on a specific combination of pad/heatsink flatness combination will also play its roll.

So, if we come to a conclusion (not saying that this is) that a stressed chip waffer causes a degradation to sound we would have to work with very flat heatsink surface plus a hard pad and clamp the chip with a bar on top of the chip using one srew to each side of the bar.

Peter, take a look at the tube vs. solid state test posted by Dr. Leach. Very informative.

I've pulled a couple of irrelevant posts at the end (including my own). Let's all try to keep things on topic and away from personalities. Thanks, guys.

Reply to Jonathan Carr (not wanting to repeat his post):

Jonathan, very enlightening. I have a story that may interest you although it concerns vision rather than hearing.

This is a man who, because of some local brain damage is blind, that is he is unaware of visual images. Yet, his eyes, nerves system and brain vision center is OK.

He is shown cards with a line on it and is asked to "guess" the orientation of the line (remember, he is " blind", lives in the dark).
Yet he scores almost 100%. When confronted with this, he gets angry, thinks he is ridiculed, he's blind for pete's sake!
So, he "saw" nothing, but was able to tell what was in front of his eyes.

Moral: you can be completely unaware of any clues or sensory impressions, but your body still recognizes them and acts on them.

Hi Jan,

Now I may have an interesting analogy for you too:

When walking down a quiet street with buildings on both sides you suddenly here pianomusic coming from an open window on the first floor.

Can you tell within a split second whether this is a real instrument being played or a recording being played back?

To some people water is just that: water.

Other people may have other sensitivities which makes me come to the conclusion that in most cases DBTs are more telling of the nature of the participants than of the DUT.

I won't make any sweeping generalisations on this kind of topic but I can surely tell a Heineken from a Stella.

Not that I think either beers are particularly fine brews...far from it.

For me, 99% of the time, yes. Live music doesn't sound brilliant, or liquid, or ethereal, or any of the other flowery reviewer adjectives for electronic devices. It just sounds... live.

Hi,

Precisely.

Now, the question is how on earth does this mechanism work?

Is it the more extended bandwidth, if any, we perceive from the life instrument?

Personally, I don't think so.

Then, by deduction, is it the recognisable harmonic correctness of the instrument that sets it apart from the recording?

That, and other factors, I think are closer to the truth.

I may have opened a can of worms here, I really don't mind, but I'm conviced that what Peter Daniel, Peter..well Analog-SA and many others hear are overtones that remind us of what the real instruments should sound like.

Now, if Peter Daniel would forgive me for speaking from experience: never tune a system for a particular result from a single recording, been there done that....it's a "faux pas".

I can 'splain it if Peter wants me to...

Cheers,
