The evolution of the original irreverent and irrelevant and non-authoritative site for headphone measurements, i.e. frequency response graphs, CSD waterfall plots, subjective gear reviews. Too objective for subjectivists; too subjective for objectivists
WARNING: Oh, if your religion is dogmatic and based on AmirNADS, then get a JDS Atom, Geshelli, or Schiit IEMagni and go away. (We do not recommend the L30 because of some issues with it exploding headphones and fixes which we do not feel will fix the problem, especially with the ESD prone OPA1612). DO NOT SPEND MORE MONEY THAN $149 and certainly stop here and do not read further.
Electroharmonix 6922EH standard (new production, barely used) #1
Surprisingly resolving and dynamic. It really grabs iem drivers by the balls and slams hard. Dynamics sound tighter than my desktop rig (see above) but that could be because of the tonal balance (a bit bass lite). Resolution is behind but surprisingly not by that much. The tonality is a bit brittle sounding if I’m nitpicking, my desktop setup sounds more natural and organic while not loosing any control or having any bloom. The FR feels slightly thin and tipped upwards but the M6 Pro not bright at all. It’s just not a warm sounding DAP. Just slightly on the thin side of neutral and slightly bass lite. Most people will probably perceive this as "neutral". Those who like solid state amps will not notice this at all, it’s much warmer and has more body than most solid state amps but my desktop rig has noticeably more body, weight and bass than the M6 Pro. When switching back to my desktop rig I kind of breath a sigh of relief from the more natural tone and more balanced presentation. Great soundstage for such a small device, it’s not close to my desktop rig but it’s still good.
I actually did not know that these utilized electrostatic drivers. I guess this is a DD, BA, EST hybrid. Integration of the different drivers types sounded pretty good in the crossover areas. However in the end, I felt the sound of the drivers was simply too different. The DD lows carried heft and physicality, were well textured, but were a bit plodding and thick. The balance of the midrange was good, maybe just nick more volume with the pinna gain spot pushed just a slightly higher in frequency than I would like - but close enough. The timbre of the mids and upper mids sounded very stereotypical BA, which tended to dominate over the electret drivers in the highs. I kind of wished I could have heard the sound of the electrets more to themselves without the BA drivers getting in the way.
Everything else in terms of technicalities is raised quite a bit from the development idea. Proper bass slam is now restored - as good as the rest of the Schiit DAC lineup > $700. Bass articulation is better than Yggdrasil. Clarity is better than Yggdrasil and Gungnir. The macro-dynamics are on another level to earlier Schiit DACs. I think the 8812 chip has been unleashed by the Yggdrasil motherboard (which really is the power supply for all the components). The SE and BAL outputs sounded more or less the same (trying to take into account other unavoidables which makes a true apples-apples comparison impossible). Retrieval of low level information is behind Yggdrasil OG, maybe on par with the current Gungnir (maybe even somewhere in between Gungnir A1 and A2 - still no slouch). If you are a microdetail whore, you may miss this. I consider myself a resolution whore; and TBH, I didn't miss it that much because it was a matter of the totality of the parts. This is why I have to say that my preference for the LIM must be caveated with other considerations. (BTW, most people need not worry about the microdetail / plankton thing - they don't have systems resolving enough - this goes for many https://www.ORFAS.org audiophiles I know.)
I will simply state a few things about the BHA-1 because there is a wealth of subjective impressions already. Is this amp the end all be all? Nope. I wouldn't buy it for the retail price. I think a lot of amps today may be competitive (but different sounding) at better prices today: iFi Audio Pro iCan, SPL Phonitor SE, Schiit Jotunheim 2, Violelectric HPA V280. Strengths of the BHA-1 are that one can largely discern the sound of different DACs through it. If we run a low-end AKM Velvet DAC, we will get murky mushy lows and mids and delta-sigma highs. If we run a hard hitting R2R DAC with smooth highs, we will get just that. This is when gear starts to get serious. The reason all DACs sound the same from Topping amps is because all DACs really do sound the same from those Topping amps, especially those with the TPA6120. Where the BHA-1 falls short is ultimate resolution and microdynamics. As such, the BHA-1 remains a fantastic deal at used prices and a good stop-gap if one is waiting for their ultimate TOTL tube amp to be built or even a good end-game if one wanted to stay with solid-state.
I had been looking for a large diaphragm transformer coupled microphone, particularly a vintagey sounding one, for some time now. The problem is that they don't make 'em anymore. Well, they actually do. But the problem is that we would have to cough up around $4000 for Neumann U47 FET. That's bullshit. I know Neumann is a respected name in microphones; but I fucking hate them. Over the decades, they've cheapened their microphones while keeping their prices astronomical. It's for the mystique, the brand name. @Psalmanazar and I talk about studio gear every now and then and we joked about recording studios may have a Neumann on hand just for the cachet, but in reality probably use other microphones.
For this project, I pretty much used the parts from the micparts T-47 kit (https://microphone-parts.com/collections/microphone-kits/products/t47-microphone-kit) with the exception of the capsule which came from @Soliloqueen. I can't down turn playing with creations from fellow members, encouraging them to make good shit. This capsule is intended to be similar to the K47 capsule of the U47 which has a bump in the presence region (it's intentional) and is still under development.
I've kind of been in what I would call the "audiophile" end of the pool as far as my equipment goes for quite a few years at this point. I never bought things based on measurements. I bought them with an eye on the measurements, but based on what I had heard at meets and at home, with the impressions of members I trust, and also what I thought of the engineering of the product in question.
This has led to some excellent purchases on my part. The loaner programs here and at Changstar back in the day have also been invaluable, thats what led me to discover my love for the Gungnir DS. Trying all this gear, and reading impressions here is what allows you to find other members with similar tastes as yours, and even if they have different tastes in gear, you can learn to triangulate what you might think of the gear in question and whether it is worth persuing for your rig.
This thread was shut down by the mods (I didn't do it but I approved) because these types of threads end up as the usual shit slinging. In the end, no one will change their mind, and there will be little talk about science or where the reality sits. There are a lot of good reasons why SINAD doesn't matter (it matters a little, but not much, and once past a certain point, it really has little correlation to sound quality). The headphones.com author cited masking and audibility thresholds. This is one of them which I have already cited, but in a much simpler way. In retrospect, I do think it's wise to keep repeating SINAD does matter. Perhaps every month I should post one reason why it doesn't matter? Well, for this month, I will make one simple argument:
SINAD does not matter because people cannot hear it.
By this, I specifically mean that Amir at Audio Science Review cannot hear bad SINAD.
I've heard ampsandsound amps before (at that prior meet and others), but refrained from commenting much because different ears, different preferences, and different setups. As many others who have been into audio for a length of time and owned fairly stable systems: it's like cooking. Good ingredients help, but ultimately it's how those ingredients are selected and put together. The only way for me to make a proper assessment is to get one of them ampsandsound amps into my house, with my sources, my headphones, and my local power. (Yes, amps do sound very slightly different - better that is - in South Texas - I shit you not).

The Holocene and Honeydew are the standouts here and the only ones I can recommend, though with reservations. Less reservation with the Honeydew and foam tips, but the treble exaggeration bothers me. It won’t bother most people though.
Unfortunately, that's where the fun stops. The amplifier in the K5 isn't incompetent. However, it's a bit below average (in all other respects except headstage) considering what is out there today. The highs are bit glarey and sometimes a bit sharp. The lows are murky. I don't know what's in the K5, but the presentation is slightly insipid. Think of it as a Magnius sort of presentation, same murky bass, glarey highs, but leaner and less warm. Or think of it as a Topping L30, but brighter and more difficult in the highs, less overly forgiving. Wait, think of the K5Pro as being similar to those default headouts from the RME ADI Pro. Yup, that's it: meh. Something's gotta give if you want expansive headstage for cheap.
The V3 I believe uses a 2" Peerless headphone driver which is widely available. The driver is angled in the frame and positioned similarly to the HD800/Qualia/SA5000. I would describe the sound as light on its feet, fast, zippy. I have not played with all the configuration options yet. Out of the box, the frequency response is neutral. There is some early bass roll-off (expected given the design of the cup and the driver) and if I wanted to nitpick, maybe a small narrow dip in upper mids and a small narrow peak in the highs. I think most will find the LTS V3 tonally lean or bright because of the bass roll-off combined with what seems like very flat bass response (most dynamics seem to have a small bump in the midbass, but not here).
he headstage is not particularly wide which may turn off some people. This is not a problem for me because I dislike wide headstages. However the headstage is quite deep, especially with the drivers hanging low and to the front of my ears, which is my preferred way of using the LTS V3. So yeah, headstage is narrow but deep! Like how real speakers properly set up the stage in front, except it's headstage instead of soundstage.
