Something I thought I would mention, I didnt really "consciously" connect it, but I have realized an important "axiom" for sound changes, psycho-acoustics, and overall musical progression is ones system. Now this MAY be obvious, pardoner moi, if it is. -- Ok here it is. --- To test a mod or change in system, it is ESSENTIAL that one listens to said change at high volumes (whatever that may be, dependent on ones power availability, speaker power ratings etc.) IMHO = a high volume audition brings out the warts. These are not detectable at low volumes. Now, I put that in a general sense. I'm talking about SMALL differences.

Example: I usually sneak these "sessions" in when my wife is out, walking the dog, whatever. So, sometimes I have limited time. So, here is a summary of what I "learned" from a 45min session. -- 1st test - sub woofer - custom crossover to lower the fx's delivered to the amp. All is good. - except I needed to rotate the sub so that the port is closer to the floor - minor tweak. 2. Recent addition of Mundorf EVO alum/oil bypassed with silver/oil. At volume the EVO sounded better on its own. 3. Some digital "hash" that I wasnt happy with - solution - I had JRiver doing the upsample to 24/192. I did an A/B comparing it to file that was previously upsampled with SOX via Foobar/min/aliasing/dither etc. Winner - Foobar. Not by a little either. So, NOW, I have to clean out my hard drive of all the "extraneous" albums to make room for 24/192 upsamples - crap - they are about 4gb/album! --- anyway - all that in less than 45min.

Thats right Greg, .. and for all you kids out there, Foobar (derived from the ancient Greek - FUBAR) is a great FREE tool for us Windows folks. Its a digital audio "swiss army knife" thats indispensable in ones digital tool kit.

I think you are correct Eric and I do the same. One needs to have a bit of SPL to hear all frequencies equally well.

Here is some info that I found:

However, as a Mac user I can not agree with using Windows  ;D

  Actually, I find this thought to be a somewhat new idea for me. It shouldn't be, as many years ago, when I would tune in a radio station in, I first increased the volume so that I could know exactly when the reception was the best. I wonder if other similar principles apply, such as listening to something in mono rather than stereo. Weird thing happened once. I bought a tape on sale of 'Synergy-Chords' . Wow, I thought, what a great deal, and I listened to it and liked it for it's dark presentation. Later on, I bought the album, and WTF? It sounded completely different! The reason was,,,,the tape was stretched, and had given looong slooow notes to the music. Completely cool when ignorance blesses us.

True story:

I was visiting my in-laws in Florence, Italy a couple years ago. My father-in-law had found a DVD of a comedy he loved as a kid, and he had just bought a DVD player so he could watch it. We managed to get the DVD player hooked up, and he started watching the movie. Sure enough, it proved to be very amusing and he was soon laughing hard. After watching the movie (bear in mind, I don't speak any Italian), he said it was great, but he didn't realize that back then everyone was speaking with Mickey-Mouse voices in order to make everything seem funnier. He had somehow forgotten that part of the movie, or else didn't realize it when he was a kid. The next day, he went out and bought a few more old favorites of his. He started watching, and then got a funny look on his face, when everyone in those movies was talking too fast, too! I still don't understand how it happened, but the audio settings on the DVD player were screwed up and everything was double-speed. I find it impossible to believe that it was just the audio, and not both the audio and video, but I don't recall anyone noticing anything out of the ordinary about the video itself. Maybe it was just because it was an old movie, and we all just assumed that the fast movements were due to the original being filmed at a lower frame rate, which often leads to old movies looking a bit off when viewed at modern frame rates? No idea...

 Yah, the stretched version was just about my speed.
