ABX testing with AQ Dragon power cords


I was talking to my dealer about how good the system sounds that he sold me. I mentioned that I had tried some new speaker/interconnect cables from a local amp/cable manufacturer & both I and the company boss agreed that there was little discernible sound difference between his cables & mine. He couldn’t understand why. He also told me that my room acoustics were amazing, top notch. He’d like me to bring my cables (& his) to his listening room & we’ll compare there. That’s for next week.

My dealer said that in his 40 years this has never happened & he was ready to rise to the challenge. He said he would send me a couple of AQ Hurricane power cords to try on my amp/pre and I’d be amazed. I said why bother, send some Dragons. He told me to connect them to my amp & preamp & I should be amazed within 10 seconds of comparing. Today I received a Dragon HC & Source power cord. I listened to some music I’m very familiar with through my Lumin T3 playing FLAC files from the attached USB. Then I swapped the amp & pre to the Dragons and listened to the same songs. No difference that I could tell. So I redid the test, one song at a time, switching back & forth. Still no difference.

I invited two neighbors over (separately) and asked them to look at my FLAC library & choose a song that they knew well. I played that for them with both sets of power cords. One said he couldn’t hear any difference between the two. The other said that one (mine) sounded like it had slightly more treble, the other (Dragon) sounded like more bass. I played a third version (turned out it was mine but he didn’t know) and he said that was the bass version. He was wrong & admitted that the differences were so small that he really couldn’t choose between the two.

I called my dealer & he asked if the difference was earth shattering. I told him no & he asked how that was possible when he just sent similar cables to another customer last week with a similarly priced system as mine & that guy said that the SQ improved 50% and was ecstatic. I said that that guy must have decided already that he was going to buy them and determined that for that money they must improve the sound. My dealer said that either my ears are those a near dead 95 year old or his last 40 years experience have been a sham. I suggested that he was selling & demoing a product to people that had a propensity to believe it worked & therefore it worked for them. I offered to have him drive here (4 hour drive) and listen for himself & I’ll swap cables while his mind is blown. We may get there yet.

I hesitate to post a photo of my listening room as experience tells me that those that are strong proponents of cables will pick it apart and blame a myriad of other crap  rather than recognizing that the 3 of us heard no difference on a high resolving system situated in a room would good acoustics... but here goes.

@dwcda nice! Thanks for the update.
So the most surprising first - you couldn’t tell that the Puritan was in your system. That’s a 180 degrees from my experience with it. Is it the PSM156?
In my system with PSM156, using 3 different power cables feeding it, it restricted dynamics, sweetened and mellowed out the presentation to the degree I couldn’t live with it. I tried their Ultimate cable and didn’t like it - brittle up top, thinner sounding although with higher res than the Classic. Running amps into Puritan was garbage. Even the dac and preamp sounded pinched. I’m exaggerating for illustration purposes but you get the idea. I sold it and don’t miss it one bit. Direct on dedicated line now. Some people love this power conditioner, I didn’t.

Second part…the loud sub. That’s potentially the culprit. Bass that’s overpowering is going to overwhelm the entire presentation. I would be testing every change in the system with the sub off. But it’s your system you do what you like. However, like I said, sub will null subtle changes. You’re going to probably tell me I’m looking for way to justify hearing the change but that’s how it is.

The fact that both of you heard power cables make a difference is cool. And that again comes down to the degree of improvement, if any. Is it worth it to you? Going back to original configuration, you would know if you can’t live without that cable you just heard. If this feeling isn’t there, move on.

That’s my take on it. And I’m looking to hear @mclinnguy thoughts on what he heard.

Oh and I forgot…having a Furutech FI-11 CU (copper) AC connectors will change the sound of the cable. Just like using Furutech XLR connectors on Mogami instead of their stock Neutrik. Good connectors make a difference and will improve the sound of the cable. The FI-11 CU is relatively cheap but excellent connector. I used it before. 

@mclinnguy read your thoughts on the comparison. The UHQR are very nice. I have Steely Dan and Miles Davis. The sounded superb when I had the table.

My room is a challenge as well. It’s not square but not too far from it. I struggled with bass overpowering everything else and I have no sub. Just my Wilson Sabrina and Pass X260.8 mono amps. Once you tune the room and system the difference becomes apparent. I still suspect the sub is a possible culprit. Also, the 4” thick GIK bass traps will suck up some of the mids and highs as well. I switched to limited range tri traps behind the speakers and the results are excellent.

When I read you heard sibilance with mogami xlr vs Absolute Copper that’s exactly one of the biggest differences I heard in my system when switching between Mogami studio gold and AZ Absolute Copper. So I don’t think you imagined it. In any case, it is what it is.
