General rule, it helps if you (and that really means you) actually read a paper before commenting instead of responding to trigger words.

1.) No, he does not promote the "time smear theory" instead he does exactly the opposite
2.) No,he does not confuse anti-aliasing and anti-imaging filters
3.) Obviously you don't know who Doug Rife is
4.) You are often doing what seems to be projecting; in this case it's an author like you relying on the fact that others (presumably from the same cult section) do not read but instead post supporting comments

Ok dad, can I now go and play? :rofl:
 
Choose a large but trackable groove modulation; calculate acceleration. From typical stylus effective mass and typical contact area calculate pressure. I don't know how to calculate temperature from pressure.


Neither do I but we need an instantaneous delta-T of 80 odd C for which I cannot see a mechanism. More fun that the usual discussions to try and find one though.
 
I'm sure it sounds better than the DAC you **** smeared and listened with Richard.

Congratulations on being more confused than usual, and full of **** too. I did not do anything at all to Richard's dac. He sent it out somewhere for 'modification.' It came back as shown in the pic I posted.

You are probably forgetful too, but a number of people in this thread were interested in finding out what was done to Richard's dac and how my own Benchmark DAC-3 sounded in comparison.

No requests for measurements were made before we did the listening and then opened the modified dac to take a few pics. It was only after people saw the pics that they started complaining about why didn't we anticipate that everyone would be asking to see measurements. We did not anticipate it either since we had not seen the inside of the dac ourselves until done with the listening. No measurement equipment was available at that time in any case, since Richard's test gear had already been packed for shipment and or shipped (I don't know which).

To recap, we listened both dacs playing PCM and DSD64. We agreed at the time of listening that my stock dac sounded better than Richard's modified one (less distorted, to me anyway), but Richard said his dac sounded better after the treatment than it did before. (I was not involved in listening to it prior to its final state as shown in the pics.)

I thought Richard said he heard a difference, not that one sounded better than the other (whatever that means)
 
This was all settled law decades ago; I don't get why it has to be refought 45 years later. (Used to 40 years in the BT thread, but time has moved on.)


All good fortune,

Because we don't know what that does (if anything) to the temperature and if there is enough time for anything to actually get hot. I don't think it does but happy to be proved wrong. 2.5 millinewtons doesn't seem to be able to cause much heating. I am also not sure about your 1000G number but need to think about that. And please no one quote the shure advertorial again....

I removed the post for that reason and for the dead link. Will write up a better one.
What is the Shure advertorial?


All the best fortune,
Chris
