I’m running it through a Vorzamp Duo, so it’s well amped. Also, having given my ears time to “burn in” - it’s not as overwhelmingly boomy as it first sounded, and I’m already much more tuned in to a lot of the stuff that’s great about the 1540, including soundstage, imaging etc. I also find a bit of eq-ing to boost the top end actually helps tone down the warmth.
I’m quite conflicted over this headphone... it’s definitely better for my needs than the Ultrasone DXP, and it sounds like lots of other ‘phones near its price class offer only marginal gains, and specifically lose out when it comes to comfort, air and soundstage, which is what I’m prioritising. The only two realistic upgrades that somewhat appeal are one of the 50trp mods (lff slant or alpha dogs or primes) or maybe an Aeon Flow Closed. Or.... live with its weaknesses, recognise I got a great deal on a very competent can, and stick with the 1540.
Aeons.. umm. Idk, but they seem to have tensioning issues and narrow dynamic range.
If you got back to post 1423, I'd have posted the list of headphones I have owned/auditioned and srh1540 outresolves everyone of those except srh940 (I'd have also mentioned flaws of every other headphone). Hd800 and clear were short listen sessions so can't comment much, but my hd800 is arriving in a couple of weeks time so I might be able to give inference. I remember it having a full phase reverb issue (which gives it that soundstage) and also an unnatural graveling/thickening of voices and a loss of finesse in falsettos on the hdv820. Will confirm if it remains with other amps.
I own stuff like cd1700 and there's barely 20 minutes I spend with those things. In a short matter of time I'm back to the srh1540. I'm keeping the rest of my headphones for my measurement system and once my project is done, I'll sell em all.
I'm yet to come across an instance the srh1540 sounded different from what the spectrogram of a song would say about dynamics, harshness, filtering, spatial accuracy etc. My only gripe is that it doesn't have the tone of 940. 940 has a tone that fits very well with binaural tracks. With srh1540, I kind of either bump the 7khz region by 3-5 db when listening to binaural or try to produce the 100-300hz dip of the srh940 + add an elevation between 7-9khz. Without that srh1540 has some kind of a vertical skew and a distance to shimmer.
Honest truth! I'm an engineer and I take pride in finding flaws. I've tried my best to find flaws in this headphone. I've had many a-ha moments only to see them go in vain when I actually look at the spectral inputs. Other than the tonal compensation I've mentioned, I'm yet to find an issue in this headphone. My nx4 is underdriving it below 50hz so I can't make assessments there (waiting for burson fun). Also nx4 is clipping for high dynamic range music on srh1540, which is why I'm certain these need amping power. I'm still not giving up, but so far.. I'm yet to find a flaw! Hope hd800 changes that and teaches me something new.
In fact I'm so fed up with trying for portable alternatives and ending up disappointed - koss porta pro, urbanite xl, and a recent acquisition, the dt1350. In dt1350 the vocals feel like they are in a constant pitch. Also it seems to gloss over the sound in a way that's forgiving but for a person like me it sounds highly unnatural. If the 940 had good build, I'd be having one at this moment. Such accuracy!!
I'm looking for a sine, and hopefully it'll fulfill my needs. If it doesn't, I'll give up my search for a portable alternative forever. Mezes were recommended but I don't think they are any more portable than srh1540. I want something that can fold.
