You dissing my rig! Yes, it is not the best. Lots of room for improvement with a better cart and phono preamp. Still this Thorens was a top LP turner in the 70's. Even has a built in speed strobe which is nice feature. I still hear people comment that it compares favorably to the Linn - LP12. But, I've never compared it to anything else, in my home.

I've heard the LP12 at a shop years ago on some Wilson Watt Puppies and it was good. I like our setup better. I've also heard top LP playback on some Apogee Duets years ago at a local audiophile shop "Audition", and it was really, really nice.

I've heard lots of good analog on top gear at shows too, and we have a very nice system overall and the LP playback it very nice with good records. I mean, I don't think you got to spend $10,000+ to hear good analog. If you do, well forget it!

Isn't sound quality a major consideration here? Are Stradivarius violins chosen due to their playability and responsiveness, or due to their sound? Or should we perform blind tests on violins in order to know which one of them is a Stradivarius?

I'm trying to get your point.
Do you say that listening evaluations aren't necessary for audio gear?

One can stick 10 idiots into a DBT, the outcome will still be that of a bunch of fools.

Same deal as with automobiles, any step up from a sheit car will sooner feel over-expensive than obvious.
Drive a nice set of wheels for 6 months, then get ready for the shock when you get into the old piece of crab again.

Joshua, that is WHY I am still in business. More than once in my engineering career, I have gotten so dependent on my measurements and topologies, that I did NOT listen to the final product. Guess what happened? Hint: twice in power amp design with Parasound. Can you guess which model numbers?

Yeah, I agree with that. I have some classical music "Digital" records and I can't say they sound all that good, kind of sterile. The ones from the 60's and 70's often sound best.

99% of audio is built with exactly those outlooks and constraints - standard T&M is the accepted publishable criterium, however those figures say little about the actual listening experience.

This is WHY I do NOT do ABX tests. I can't pass them, either. Neither can John Atkinson, or just about anyone else.
Are we deaf, but arrogant? Are we 'fools' to believe in our own listening comparisons?
No, you're just human.

I know that's difficult, and in some cases impossible for some people to come to terms with. But that's nothing a small dose of humility can't cure.
