@aaf evo for selling me his PW Audio 1950's, I decided to grab em after using the PW Audio 1960's two-wire. While the 1960's 2-wire is a phenomenal offering from PW, it is unfortunately too bass heavy for the Empire Ears Legend X.
I'm lucky enough to have both the PW Audio 1950's and 1960's 2-wire, so I might as well share some thoughts to all of you lovely head-fiers!
Check out my signature for the chain. As you can tell, I'm a huge fan of copper, which is why PW Audio has emptied my wallet.
PW Audio 1960's 2-wire: First thing that grabs you is the bass, holy moly if you thought the LX had bass... It's great for rock/indie/jazz/classical, not so much techno, house, trance, anything with a heavy kick/bass. The bass on the 1960's makes it fatiguing to listen to for long hours (as many mixes are several hours long). The separation and imaging is superb, better than the Ares II by a long shot and edges out the PlusSound Exo Tri-Copper. Soundstage width is much greater compared to the two previously mentioned cables, and depth increasing slightly as well. The Ares II+, while a great stock cable compared to many other offerings from other companies, is easily beat out by the PS Tri-Copper; the Ares II+ sounds congested in comparison to my other cables. The mids are not the front and centre of the 1960's. The timbre and tone that copper creates with mids is something I thoroughly enjoy and the 1960's delivers, hands-down. There is great extension in the highs, no brightness or sibilance whatsoever added. Overall, I would recommend the 1960's to anyone looking to get a TOTL copper cable and those that don't listen to 4 to the floor, bass heavy music. While very expensive at 1K usd, there are a few floating around the used market.
PW Audio 1950's 4-wire: WOW, was the first thing I said when I plugged these in. Thom Yorke's voice just opens up like a book. There is so much air and throatiness behind each word, it's amazing. The LX pairs wonderfully well with the 1950's. I always wanted a little more bump in the upper mids due to the way that the LX is tuned. The 1950's doesn't bring out really add anything to the overall signature of the LX, it just makes it better. The bass's ASDR is perfect. Soundstage is something PW Audio is known for and there is gobs of it here, wider and deeper than the 1960's (probably due to the impedance difference in 2 to 4 wire). Separation is better than the 1960's due to its slight bump in the upper mids giving more emphasis on the instruments in rock/indie/jazz stuff that requires more mids. The mids are where the 1950's really stand out, guitars, synths and vocals really shine now with these babies in. I haven't noticed much of a difference in the highs when compared to the 1960's.
The PW Audio 1950's are going to be on my Empire Ears Legend X indefinitely.
