I just got home last night after a long trip away. So, the first thing I wanted to do is try out my C9 with all of my full sized cans. After spending so much time with IEMS over the last few weeks, it's really nice to hear full sized headphones again. First and foremost, the C9 pairs the best with the Hugo 2 for full sized headphones. My Hiby R6 2020 isn't high quality enough to really achieve their full potential and it is very striking how much so. I need to find a DAP that pairs with the C9 as well as the Hugo 2. Any recommendations?
Anyway, I've been listening to HD 800S, ZMF Verite Closed, Hifiman Ananda and Focal Clear. All headphones benefited significantly from the pairing with the C9. The HD800S gets a better bass response to go along with the huge sound stage and overall clarity. Still can't beat them for Classical Music and Jazz. Bass response isn't good enough for other genre relative to the alternatives.
ZMF VC really gets to the next level with the C9 + Hugo 2 as I reported before. I had family and friends listen to the VC and they all universally said this was the best headphones they have ever heard. They wanted to know it's price to get one for themselves. They took a pause when I told them. The detail and richness and 3D presentation of the sound is really striking. My friend said he had never heard guitar plucks before in the songs he listened to.
The Hifiman Ananda really saw a big improvement in sound quality. I love the tonality and sound signature of the Anandas, but the problem I've had with them is the bass response and the timbre. The bass showed a remarkable improvement in level and texture. Still short on punch and slam, but great overall improvement. I was going to sell them, but the improvement was good enough to keep them.
I just picked up a Focal Clear from the close out at Headphones.com of the OG Clear. I must admit, I am a bit disappointed in the Clear OG relative to the others on this list. I loved it standalone and they sound great if I don't listen to anything else. But, when I A/B test them against all of the above, they come out last. They are new, so maybe they need to burn in. I decided to get a Utopia to replace the Clears in my full sized headphone line up.
All and all, I love the Hugo 2 + C9 pairing for full sized headphones. I think this is not an obvious set up that can be on anyone's list as their permanent desktop system for a TOTL system. You can get a full sized desk top set up, but with the Hugo 2 + C9, you have both a transportable and a desktop all in one.
Edited to note: The C9 does a really good job at accentuating what a given set of headphones is good at. When listening to all 4 of these headphones, they all sound distinctly different. You need to spend time listening to a lot of music to determine which version of the music you prefer. To me, it's like having 4 favorite restaurants that I can sample any time I feel the urge for that specific flavor.
