As I've mentioned I spent yesterday with Bill listening to music and swapping power cables between my do-it-yourself cable and Pete's Triode Wire Lab Seven Plus cable.
Inserting Pete's cable into the mix made an immediate impact in improvement on the quality of the sound. First of all, in the bass, it became more detailed and lifelike and a lot of 'boominess' that was there that I hadn't realized was present - disappeared.
The overall presentation of music gave a sense of more space and air around the individual instruments. At the same time the appearance that music was coming out of the speaker boxes disappeared, the presentation took on a holographic or 3-D presentation while adding a width and depth to the soundstage not previously there. Quite simply, I was shocked the overall improvement, never having realized I didn't have all these attributes in my presentation already.
We did a good portion of listening via CD, and one of the first things we both noticed was a lessening of glare in the sound. The presentation was overall more lifelike. The same is true for listening to digital music via squeeze box, in fact even more so. Again the addition of a more lifelike quality to the music was significantly noticeable to both of us immediately.
And of course the same held true when we listened to vinyl. One example, while listening to a Stan Kenton version of Over the Rainbow, the finger work of the bass player on the upright bass, not previously noticeable, was readily apparent as he worked his way up and down the scale, it was a little spooky.
And the way the Triode Wire Lab 7 Plus improved base was shown in an additional manner, as follows. I've been experimenting with adding a small powered sub to my two channel system, I simply ran wire from one of my main speakers to the high-level inputs of the sub for now.
Though this setup has given me an appreciation for what a sub can add to my system, it's been with one readily apparent negative aspect, my soundstage has shifted to the side where the subwoofer-speaker combination is, or to my left. I assumed having the sub mated to the speaker has affected the load that the pair presents to my amp in such a way that it's shifted the soundstage in reaction to this. Adding the Triode Labs power cable to the mix immediately placed the soundstage back where it belonged with every instrument in its place with air around it - it was simply freaking amazing what was happening.
And these improvements seem to be a family trait of the Triode power cord family. I had recently purchased the 12 Plus power cord for my DAC, and so we swapped out the 7+ for the 12+ as the main power connection to my PS Audio Quintet. Again with the 12+ in place all the improvements listed above were still evident, the only difference is maybe a loss of the lowest of the low end grunt in the bass, otherwise a marked improvement all around.
All in all of full day was spent in both analog and digital, listening to an assortment of rock with a little jazz thrown in, all in all the improvements mentioned were there for everything we played. I simply have to rate Pete's handiwork as one of the best values in sound improvement I've come across, and if that sounds like hyperbole all I can say is give them a try to hear for yourself.
