Yes! The CA Cascade are sooo much fun!
I think that planars for me are on a separate complimentary path, in that they are on average more expensive, and that they do things differently. I would consider Planars as a more advanced purchase for when you have more experience with what you like. But that being said the HE4XX is very cheap and does a lot right and would be easily a first purchase recommendation for people getting into the hobby. The problem with both of these headphones for people getting into the hobby though is that neither of them are readily available. I have had the 4XX (gave it to a buddy I thought would appreciate getting into this hobby but needed a push down the rabbit hole). I have currently the M1060 and the M1060C (in pieces, trying to mod an aftermarket LCD2 headband onto it). Will be getting the Mobius hopefully soon. I have listened to some of Audeze gear but not extensively enough to pass “judgment”. I would love to hear more planars in the future, but we will see. I think I will begin focusing on amps and DACs next.
The funny thing is that I kind of found my sweet spot with headphones, I tend to currently grab one of these on the regular, HD700/HD800/Fostex X00/Cascade/Andromeda not necessarily in that order. They all fit easily into what I want from them. The Elex/M1060s/58X are just kind of there, I may have to sell them off to good homes here in the future lol. The CA Comet is my go to gym IEM with the MEEBTX1 bluetooth band. Outside of those I think it is time for more experience with like I said before amps and DACS =)
