Yes, my comment was a bit ambiguous. To be more precise, my typical solo DAVE volume control setting for HEK V2 was -32dB.
HMS reduces output by 2.75dB, rounded to 3 dB for easier maths. Therefore with HMS included, I should theoretically now listen to the same track at -29dB to get the same output.
Swapping HEK V2 to SE adds 6dB efficiency (according to hifiman), so I should now be listening to the same track at -35dB.
But in practice I now listen to that track at -38dB, so it seems I can get the same musical hit with 3dB less volume.
By musical hit, I mean the tipping point at which "background listening" turns into something more like "you are there", where the focus and dynamic impact seem to all snap into place to demand my attention.
Further volume increases can further the effect, but each additional 1dB step is not as important as that initial 1dB increase. And this matters to me because I don't want to exacerbate my mild tinnitus.
Some others work with half dB volume steps which I find very useful to really fine-tune loudness levels. I don't know why Chord uses whole dB steps? To me 1 dB louder or lower can be quite a step.
But I am also finding that with the Wave Fidelity BNC cables I am trying in my system I also don't need to turn up the level as I used to have to do to hear very low level inner detail clearly.
With a calmer clearer more open window to the music I enjoy things even more than with the stock BNC.
Very OT maybe? But since you mention mild tinnitus, have you heard about the new treatment apparently helpful both against traumas and also tinnitus,with electrical stimulation at the point just above the eyebrows on the forehead?
To an old yoga freak like me, familiar with that buzzing point, it looks almost as if the third eye brain connection may just have been validated scientifically?
According to the TV documentary I saw recently ,there is even a direct nerve connection between that point on the forehead in Yoga referred to as the third eye or Agnya Chakra and deeper regions of the brain like the amygdala.
And electrical stimulation of that point on the forehead has obviously been shown to be beneficial not only for patients with lingering traumas, but also tinnitus.
PS The yoga tradition "third eye" was never mentioned in the programme that is just my own personal reflection when I saw the point where they put the plaster.
The treatment seems to be firmly based on accepted science and since I first forgot to mention where I saw this, it was in a recent episode of Mosley's "Trust me I'm a doctor" on BBC.
