Ah gotcha. Seems like at the very least you really wouldn't want to use digital volume control on a 16 bit file. With all the headroom of a 24 bit file, though, looks like you would need to reduce volume by 48 dB before you may run into resolution issues.
You have tried all outputs on HA-3A already? including the 4.4mm output? We have lowered the output of 4.4mm phone output in order to work with sensitive headphones or even iEMs, so I am surprised if you are still having volume range problems.
I have tried HD800 with HA-3A, I don't recall having a volume range problem at that time, but that was a long time ago when we launch HA-3A, I would be most appreciate if any Antrium or HD800/HD800S users can chim in.
my hd800s on 4.4 is usually set on 9o clock for gaming, for listening 10 o clock is bareable but wouldnt recommend that. My he 1000 V2 (not stealth, but older version) is good at 10 o clock, so it needs a bit more power. But tbh, i have no idea why anyone would ever need something more powerfull then this amp

Impedance setting makes a lot of difference in terms of output power.
Let's illustrate the difference by assuming the Low impedance = 32 ohm, and high impedance = 300 ohm.
The rated output of 4.4mm phone out of HA3A is 230mW at low impedance, and 400mW at high impedance.
We can work out the Vrms output of the amplifier at these two setting by the following formular:
So when you connect HE1000V2 to HA-3A and set the impedance to LOW, the rated output of the amplifier in Vrms is 3.84V
Alternatively, when you connect HD800S to HA-3A and set the impedance to HIGH, the rated output of the amplifier in Vrms is 15.49V, which is roughly 4 times more powerful than the Low impedance setting.
Therefore, HD800S at 9 o'clock volume (at HIGH impedance) should involve more power then HE1000V2 at 10 o'clock volume (at LOW impedance).
agree
I have Snorry Trion (86 dB/mWt) that sound loud at 12 o'clock, but they don't driven. if I increase volume I hear more distortion. The volume level says nothing about the power of the amplifier
Mazda 6v6: linear, clean, punchy, my reference tube when testing new tubes
Visseaux 6v6: linear, warmer mids, has more unique sound than Mazda.
Sylvania 6v6: warm but not overly so, these have a really nice tone to the lower mids, guitars do really crunch with these. Great with Philips ecc82/e80cc.
Nice universal warm 6v6 tubes are Brimar, british Tungsram, Westinghouse Canada, Tungsol or RCA vt-107: warm, nice mids, strong bass(especially RCA and TS)
Raytheon 6v6: mid focused tube similar to GEC kt66. Ridiculously good (warm) combination with Tungsol black glass and Japanese black plates 22de4. Best combination for vocals.
That's the first tubes that come to my mind which are easily available. Surely there are many more.

Nice summary.
I love the warmth and bass of my Brimars. I tried some RCA and Fivre too which are quite popular, but they didn't have enough (sub)bass for me. (They did have a slightly bigger and airier space though.) Raytheon sounds appealing.
I would also add, that the 12AU7s you combine the 6V6s with matter too. It is very much about finding the right combination. The Brimars for example can sound too warm with certain 12AU7s but very satisfying with others.
Tungsol vt-107 have surprisingly lots of bass. RCA vt-107 is not far behind. Later RCA 6v6 sound different (1950s and 6v6gta)
For more subbass I recommend La Radiotechnique/Mazda ecc82 tubes or Philips ecc82 for bass in general. Both are fairly linear and pair well with all the warm tubes mentioned above.

Yea I can make a summary. But there will be lots of tube rolling involved. Some combinations only work with a certain rectifier for me. Your Sonical results might differ because of your headphones, DAC and personal preferences.
Recently I got some rare early 12au7 tubes in. Lots of new toys to play arround with
