Moving on to "First Times," my heart begins to race once more. The bass feels overpowering, the dynamics have notably improved compared to the 1960s, vocals come across clearer and sweeter, and the overall sound now boasts an abundance of detail. However, I can sense the progress in "First Times," but I find myself only able to listen to one song with this pairing. It feels overwhelming for me, despite it representing a step forward from the old sound. It's simply not a combination I'm accustomed to.

I also tried cross-listening these two combinations, and I found them appealing:

Fir Audio M5 CIEM paired with PWaudio "First Times"

Fir Audio Xenon 6 paired with PWaudio'"The 1960s" 4-wired.

This further underscores the importance of matching cables with headphones. Merely being expensive doesn't guarantee that they will mesh well together. Upgrade cables only alters the sound quality. Every headphone or cable manufacturer carefully considers compatibility when introducing a new product, adjusting the sound to align with their preferences or to enhance the performance of their existing offerings. It doesn't guarantee that any combination will suit your particular preferences. Therefore, after selecting headphones, it's crucial to personally explore various cable combinations.
