This i agree with, it doesn't compete with open backs. But the bass is to die for. It's highly setup dependent though. On the TA-ZH1ES it was boomy, unfocussed and just...bad overall.But if you're looking for upper midrange and treble detail, while it is decent, it doesn't jump out at you.
This i don't i've compared them to the HE1000se, Utopias and lcd-4z and found them on equal footing or better, with the one exception being the speed of the HE1000se. Compared to Stellia and LCD-XC i find them better and more comfortable. While on a Hugo 2 differences i'd call them in the same ballpark, on Dave , and adding the M-scaler later i feel like they scale up better. In my current setup the soundstage is so vast that on some tracks you can hear the music coming from slightly behind you.they really didn't compete with other flagships
Ofc YMMV and everything matters, from mains filter to keeping the M-scaler on battery ,a decent streamer, etc. Also the stock Z1R cable is pretty bad, I'd recommend a silver one. And i'm a huge cable hater.
I'm itching to replace them and haven't found anything i like more yet. Had them since they came out. Admittedly i'm looking only at closed backs and haven't tried the Verite Closed , no place to do it.Is it really in the same league as the cans that cost 2x more?
But even in the open back realm i feel like the difference is so small i'd rather have the closed back isolation from my mechanical keyboard than the "extra" stuff on the open backs. I'm hoping the Stealth can complement them , if not i might bite the bullet and just get the Audeze CRBN + an amp for that ultimate detail and speed and be done with it. I'm not counting on any of them to provide the bass i want since i already have that in spades on the Z1R. Drum kicks are just unreal. Impact is amazing and sub bass is as deep as it gets. As detailed and fast as planars are, i haven't found one yet that comes close to that physicality. Haven't tried the Abyss yet though.
I know the Z1R are polarizing but they are very dependent on the electronics used and since you're already using a Dave, and what you're searching for is exactly what i love about them i can confidently recommend that you give them a try. With a decent silver cable preferably.
