Music And Movies
I have been doing a lot of listening to Jimi Hendrix’s Blues (MCA) disc. I’m a huge fan of Hendrix and am familiar with the disc, so it seemed a great place to start. Prior to adding the PurePower to my system, I sat down and listened to this album in my Meridian G98DH. Then I connected the PurePower to just the Meridian gear and I must admit I wasn’t ready for what I heard. “Born Under a Bad Sign” had improved detail and a more believable sound to it. My system is pretty revealing, but the addition of this device really took it to a new level. I then connected my Mark Levinson 433 to the unit, as well as all my sources, and went further. “Catfish Blues” is my favorite song from this album, and with the PurePower, it gave me an experience I won’t soon forget. Every note had more detail and a more natural sound to it than I’d heard in my system prior to adding the unit. Every lick of the guitar and rap on the drum was perfectly done, and Jimi’s voice sounded even truer than before. I was worried that amplifier would draw more power than this unit is rated at, so I gradually turned it up and checked the percent usage. Surprisingly, I was able to crank it to extreme levels without overloading the unit.
I moved onto Keb Mo’s Just Like You (Sony) on SACD in my Teac Esoteric DV-50s. I had often heard the DV-50s benefits from a power regenerator, but until now hadn’t tried one with it. I should have. “That’s Not Love” came through with more air and detail than before I added the PurePower to the system. Bass had more slam and immediacy to it, while each note of the guitar was more clearly portrayed. The resonance of the acoustic guitar on “Perpetual Blues Machine” was amazing, better and more lifelike than without the PurePower. “Just Like You” had full and rich bass, while the small details of the bells in the distant background came through more clearly than before the addition of the PurePower to the system.
I was pretty amazed at what this device did for the sound of my system, especially given its baseline. To see what effect it would have on the video side, I plugged my Sony KDS 70XBR2 rear-projection LCD HDTV into the PurePower and started playing some movies. I cued up Deck the Halls (Twentieth Century Fox Home Entertainment) in my Toshiba XA2 reference HD DVD player and was treated to excellent color and contrast right out of the box (don’t ask about the movie itself). I switched the player and TV from the PurePower to the wall outlets and easily saw less brightness in color and less contrast as well. When the PurePower was used, reds were deeper and richer than without it and the contrast from the many snow-filled scenes was better. I swapped the PurePower in and out a couple times and re-watched some scenes; the picture was clearly better with the PurePower in line. Adding the TV did significantly up the power usage and, playing films at high listening levels, I saw readings into the mid-80 percent range, but never felt the sound to be compressed or that the unit was being overtaxed.
3:10 to Yuma (Lionsgate Home Entertainment) on Blu-ray was my next film to test. The movie is filmed almost entirely in the plains and as such is full of oranges and browns. With the addition of the PurePower, the colors just seemed smoother. Watching the movie without the PurePower in the system seemed to make the varying shades irregular, while adding it back in made them seem more lifelike. Reds from blood were brighter and more real-looking.
Even my cable TV was improved with the PurePower 700 in line. I saw more natural colors with improved edge detail that was clearly obvious upon switching out the unit. Colors seemed more real, especially skin tones. The change was so substantial that it was as though I had changed the picture settings on my TV, but I hadn’t; I had just allowed my TV to reach its full potential. This was obvious on HD, as well as SD channels.
