"Thank you for sending me the QPI Series Au. I tried it today plugged into two different duplex outlets in my listening room. I plugged the QPI Au into a duplex outlet with nothing else plugged into that's on the same circuit as my NEC CD-730 CD player and Emotiva XPA-200 amplifier (each is plugged into separate duplex outlets on the same circuit).
And I also tried the QPI Au plugged into a duplex outlet with a switched outlet and unswitched outlet with the amplifier plugged into its unswitched outlet. I thought that there was better sound with the QPI Au plugged into either outlets that there was an all around improvement to the sound, but I preferred the QPI Au plugged into the switched outlet with the outlet being switched on. As a general rule I've never found the trade offs of line conditioners or filters either in parallel or inline worthwhile because their downsides always have out weighed their upsides until now that is!!! I usually have pretty good power (there's only one other house on my transformer and it's at least 300 feet away), so I don't haven't been using any power conditioning or line filters. But having said that I have some really weird passive tweaks on my breaker box that include a 9 volt batteries and similar tweaks on my two components. That I'm quite impressed with the improvements in the sonics and musicality I'm experiencing is a tremendous understatement because it's the first time that any AC power conditioning or filtering haven't had downsides to my system's sound and musicality that nixed their use for me.
Here's some of the wonderful upsides of using the QPI Au that my words alone can't express, and it's not as if I didn't already think that I had one of the better sounding audio systems in our solar system. The images are more focused and more holographic, there's deeper and tighter bass (my bass was already the envy of every audiophile who's heard it), midrange, and extended highs. My tweeter is a monopole Linaeum with only a single treated and modified 6.2 microFarad Clarity cap and with the two other drivers playing full range. One of the tracks I listened to was track no. 6, Hotel California from the Eagles CD Hell Freezes Over. I don't necessarily use that track because it's my favorite music by any means, but I use it because it's a live recording and has a number of elements that help me quickly hear changes to the sonics and musicality of my audio system. Of course I'll be using the QPI Au from now on and demonstrating it to my music-loving audiophile friends and potential customers. It's humbled me in a good way as it always does when just as I think emotionally that my system couldn't get any better (of course intellectually I always know better but it's fun at least for a little while to believe otherwise) to think that without the QPI Au in my system couldn't sound any better or connect me even more to the music I love and even some that I love not so much. But once the QPI Au is heard in one's audio system, there's no going back. I'd like to audition the QPI Pt. And I'd like to hear the effect is of using two or more QPI Au simultaneously/in combination with other QPIs. One really has to hear its effect to truly appreciate what a great improvement it makes even to such an already great system that i believe is probably one of the best in our solar system. I've despaired of ever finding a power improving product so, Kudos and more Kudos!!! So how to I become a dealer?"
