Kind of late to party here, but I received 3 pairs of GE's a few weeks ago. I've been playing with them in different locations with VERY different results. I could write pages of comments, but I don't have the energy or desire to do so. So here is a short version:When I attached 1 pair to the negative speaker terminals on my speakers, the sound changed immediately. It was not for the better. I lost some upper frequency tones verified with certain tracks I use for critical listening. It didn't take more than a day for me to figure out that I couldn't live with the sound I was getting.I tried a pair of GE's on the amp's negative terminals with the same effect. I even tried a pair on my preamp and that really took away the detail and resolution of the sound. Not good.So before I gave up on the GE's altogether, I decided to try them on my speaker's positive posts, the sound was completely different. I lost no detail or resolution and I'm convinced I've gain a level of clarity, decreased background noise, slightly more defined bass, and increase separation and sense of space. Ok, this is good, but why the POSITIVE speaker posts? This sent me on a quest to find out if one of my components was inverting absolute phase. I couldn't find any information on my gear that stated the phase was inverted. Then I set out to figure it out on my own.I can't seem to definitively figure out if my absolute phase is inverted or not. I tried the battery test and couldn't really determine if the driver was moving in or out as it bounces quickly and I just couldn't tell for sure. Then I did some tests with my finger on the driver and convinced myself that the phase was inverted. So I flipped the speaker terminals at my amps and I convinced myself that the drivers were now in the proper phase. This I'm 15% certain of... So now I'm listening to my speakers with the absolute phase inverted from where I've been listening for the last year or so. My thoughts? I'm NOT SURE! This kind of stuff drives me INSANE!! I listened for an hour without any GE's installed and got used to the sound that sounded really familiar to me. It is possible that the bass sounded a bit punchier, but I won't state that as fact. It's more of a gut feeling than anything. I didn't really notice anything else different about the sound, so inverted absolute phase doesn't seem to be a horrible thing for me. Time to install the GE's again...I installed a pair of GE's on my negative speaker posts and listened again. Again, the sound seemed to change similarly to when I installed them on the positive speaker posts with the phase inverted. I could hear slightly increased clarity, a more quiet background, slightly more defined bass, and increased separation and sense of space.Totally confused by all of this, and frankly a little sick and tired of messing with all of this, I decided to just listen. The sound is really good, but I had really good before. However, it is now a couple of days later and I sat down to listen for a while. The sound is amazingly good. It's one of those deals where I can just let the music play regardless of what's on. Everything sounds really great. I would say it's better than what I had before the GE's.Big picture, I'm still VERY confused. Are my speakers now running inverted absolute phase or not? This I find a bit upsetting. I need to figure this out. I also need to play with the other GE's I have, I'm just not in the mood for now.
Wikpedia's definition of audio nervosa, see below.
Just wondering-Anyone do any SPL measurements, comparing with/without GEs? Seeks like there's some attenuation to me.
TJHUB,I'm so late to the party, it's probably over! However, I want to share a thought with you on your experience regarding the phase inversion. First, is your source strictly CD/SACD/DVDA based? If so, this may explain why you preferred the sound phase inverted. I was recently informed that approximately 90% of all CDs, SACDs, DVDs, etc. are phase inverted. So, if your system has correct phase throughout, you will get the best sound by inverting the phase in your system as this will correct the inverted phase from the source material. I recently made this change and can't believe how much better the vast majority of my CDs and SACDs sound.I'm getting ready to order some EVS Ground Enhancers and was contemplating which speaker terminal to attach them to, positive or negative. You may have already done the ground work, but I guess I'll have to try them both ways as well. Now, if I can just figure out how to order these things. I don't find any way to do so on their website, and there isn't any phone number to call. Does one just send them an e-mail?Cheers,Dean
