I second Hawaiikid's comments down to the last word. In my system that is exactly how Pursang sounds, and I have the same reaction to my comparison with AZ Satori (a single run, not shotgun) as well as with Magnan Signature. All the signal cable in my system is Pursang - two sets of interconnects and the speaker cables.
That said, I have a caveat based on a couple of recent experiences with the interconnects. The first one was whern I substituted Pursang IC into a friend's system (AI Mod III pre, Trimax 805 amps, MM de Capo i's) in place of his Wireworld Gold Eclipse III+ from pre to amps. In this situation the Pursang sounded very detailed but lean and tipped-up, much like the stereotypical conception of "silver wire".
The second experience was in a different system with a Wadia, Hurricanes and Total Eclipses. We put the Pursang between the CDP and the amp in place of his Wireworld Gold Eclipse 5. This time, with the Hurricanes in triode mode it sounded similar to what we'd heard in the other system, but less obnoxious. When we switched the amps to pentode mode everything just came alive, and I heard the same effect I get in my own system in terms of extension, immediacy, depth, palpability, musicality etc. In this system, with the amps in triode the Wireworld sounded "better", but in pentode the Pursang left it in the dust.
The local opinion of four others who have heard it is that the Pursang speaker cable is more of a sure thing than the IC, and that it's unequivocally superior to the AZ Satori or Magnan Signature (which is the cable the other four use). My opinion is that if the system sounds worse with Pursang in it, then the problem is likely elsewhere.
My system is an Audio Note 4.1x DAC, an Audion preamp, Wavelength Triton amps and Coincident Total Victory speakers, so it's my feeling that the more good tubes there are in the system, the better Pursang will work. IMO, that's because there's more music for it to let through. If there's crud being generated at any point in the system, the Pursang will not hide it.
