Perfectly valid test to me. - hukkfinn 08:13:36 08/24/06 (0)

Do you have a polarity switch on your preamp? - Dave Pogue 10:01:12 08/21/06 (4)

Shhhh... you might attract the attention of that polarity psycho! :) [nt] - Steve Cortez 16:41:12 08/21/06 (2)

Excuse me! That's Polarity Psychoâ„¢,ok? We MUST stay abreast of such things...N/T - musetap 18:02:43 08/21/06 (0)

A slight change in volume (SPL) will be audible ... but so what? - Richard BassNut Greene 08:58:32 08/21/06 (5)

You didn't mention if the tweak caused a small change in volume (which could be audible) nt - Richard BassNut Greene 09:30:35 08/22/06 (3)

A small change in level will often be mistaken for a change in quality - Analog Scott 12:05:11 08/22/06 (1)

"Clark is clearly being sarcastic." No, the word is "realistic". Those people will never be happy... - clarkjohnsen 09:13:23 08/21/06 (5)

Sounds like a fun session :) I'm awfully curious what the tweak was, I've tried something similar... - Steve Cortez 17:53:22 08/20/06 (0)

Make lots of tests - Caymus 11:22:00 08/20/06 (0)

It was a great test, Phil; way to go. Obviously the fans of DBT don't accept it... - jeffreybehr 10:05:18 08/20/06 (3)

Not a thing. I'm responding to your statement... - jeffreybehr 14:37:12 08/20/06 (3)

Itâ€™s still better than sighted listening tests - Caymus 11:46:08 08/20/06 (1)

I disagree. One could get unfounded confidence - Analog Scott 13:23:54 08/20/06 (0)

Great response, Scott...NOT. Do you think those who raised their hands DID NOT hear a change? - jeffreybehr 09:53:51 08/20/06 (3)

Phil, try to pay no attention to Scott. Your testing methodology is perfectly valid... - jeffreybehr 12:23:27 08/20/06 (1)

Actually few experiments are done double blind - Norm 10:40:17 08/20/06 (2)
