Recommendations for next headphone


I currently have the Focal Utopias, Abyss 1266 Phi TC, Focal Stellias, and Hifiman Susvara. I have a number of amps and DAPS, the AK SP2000, Ifi audio, Focal Arche, Benchark DAC3 HGC, Woo Audio WA11, WA33. Also using Naim ND5XS2, Auralic G2.1, and PS Audio Directstream w/bridge DACs. Not looking at electrostatic at this time, until ready to plunge for a top of the line amp for that. Not considering Raal. I do like detail, clarity, and the more bass the better, but detailed bass, not muddy. Dosnt have to be super fast, I have that and more covered with what I have now, but I do enjoy different types of sound, one kind is never enough to satisfy. Meze Empyrean? Sony MDR Z1R? HD800S? HEDD ? Others?

I bought the DAC3 to use as a dac mostly in a two channel system, but now am using the Naim and auralic streamer dacs. Also added the meze and hedds to the stable last night, so now to see what else to try. 
I'd throw the LCD4 in the mix if bass is your thing.  The Sony MDR-Z1R are very close in performance to the LCD4 and can be had for a lot less.
Last night I had a problem with my work. So I started some work at 9PM and finished at 5AM this morning. All that time I was listening to the Meze Empy with WyWire Platinum XLR. I was streaming the "1976! Songs of the Year" playlist on Tidal. It was so enjoyable that after I finished my work I stayed up a little longer listening to a few more cuts. This was with the HPA4 and DAC3B.

I love this headphone system.
