I got so confused trying to figure out what my new Ares 8-wire w/Psquared plug was doing using my not-fully-burned-in MD Zeus that I swapped it for my regular-plug 8-wire. Then I took my XR for a ride with the Psquared. Wow. Now I know what it is doing. It increases detail, it improves placement within the soundstage, it improves clarity. Imagine sound as a tomato and you use a sharp knife to cut the tomato into slices, and those slices are what you hear within the soundstage. Then imagine a
really sharp knife cutting the slices into even finer pieces of tomato. Weird metaphor, I know, but it seems that the Psquared is delivering finer cuts of sound. It's hard to describe, but it is clearly happening. For $50 it made a whole lot of difference.
From an interview
https://www.headfonia.com/q-n-a-saturday-effect-audio/2/ Psquared is about halfway down.
HFN: Can you tell us a little bit about the PSquared plug?
EC: PSquared plugs employs the plating of 2 noble metals – Palladium & Platinum both which is in the same noble metals group as Rhodium but complements each other. Palladium & Platinum plating is commonly used in high-end premium HiFi setup and has yet to be explored within the Head-Fi community. We collaborated with Oyaide to bring the PSquared plug to the Head-Fi masses and thus far, response have been very well received.
HFN: What are the benefits of your PSquared plug?
EC: PSquared brought in a very rich and dynamic tone while enhancing the highs to be crispier and snappier. Reviewers have stated that the sound stage has enhanced greatly wherein a 3.5mm PSquared performs effortlessly well as though it is on a 2.5mm balanced configuration through the Astell & Kern players. One key noticeable difference is that PSquared plugs helped define the dimensions in which the music reproduction usually plays at. One could “See” (hear) better the placement of instruments and performers in a decently mastered source.
I'll listen to the MD Zeus with my regular cable tomorrow and try to get an idea as to how close it is to the XR.
