I was planning on getting the v281 for my LCDX until I saw this... did anyone else pick up on the rather alarming bass roll off that Tyll measured?

Even if the v281 sounds full bodied subjectively, the roll off concerns me

You will not hear anything below 20 Hz. So, even if measurements are correct, this is far from alarming.

Even if went to 20hz, you're not going to hear it on your headphones most likely anyway.

It’s -1dB at 30Hz and -2dB at 20Hz.
What’s so alarming in that?

I can personally attest to the fact that the v281 is an absolute perfect match for the LCD XC. As the LCD X sound signature is somewhat similar, I think it would have to be good on the X (I have also used with LCD-3F and 4s with great results).
 
I get the best bass response on my XC with the v281 when compared to any of my other amps - including a Auralic Taurus mk2, Marantz H Dac-1 and a Wadia 121 - if that alleviates any of your concerns. I actually upgraded to the v281 for the XC from a Woo WA7 specifically because I wasn't getting the level of bass response I wanted with the Woo.
 
I use the Marantz HDac-1 primarily with the XC now only because its in my bedroom and that's where I need closed headphones. The V281 is better, but the HDac-1 is a fantastic match for the XC as well for the price if that's a factor. (Use v281 primarily for my 4s as they need the juice)
 
As far as DACs, I've used both a Chord 2Qute and a NAD M51 with the v281 similar results in regards to bass.

Fried replied my email, "only the 182 relay option" has the roll off, those with regular and those with motorised volume control are unaffected.

This measurements are strange because there are another measurements without this roll off.
Here they are: http://www.reference-audio-analyzer.pro/report/amp/violectric-hpa-v220.php.
This is V220, but this does not matter, I think, because they both were made for SE outputs.

Would one suggest the Relay upgrade if its in budget? Or just go with the motor?

I'm selling my V281 relay one if anyone is interested.

If so, it is very interesting, which part in this volume control may produce such roll off. And why this option is considered better. I wanted to upgrade, but now this option becomes mistrusted in my eyes.

I have just sent back to lake people my v281 to check the functionality of the relay volume pot. I now wonder if I should ask for a downgrade as well (as kindly offered by Fried).

I'm fairly sure my hearing only goes down to about 25hz anyway.  
Would I have ever known that I am losing a decibel in the lowest bass I can possibly hear?  Noo...

You can try the following to check it: http://www.primefan.ru/pt1.html
1. Pink noise at -12 dB FS - Third-octave band 20 Hz (17.83 - 22.43 Hz)
2. Pink noise at -12 dB FS - Third-octave band 25 Hz (22.30 - 28.03 Hz)
 
(be careful with the volume)
 
I'm sure, you can hear it. Maybe not as clear tone, but... I think this has impact on the sound.
 
The words used here to describe the difference between the volume control options remind me the words, in which I can describe the difference between V100/V200's low-cut filter turned on or off.
So, I'm not sure, what exactly am I buying for almost $700: better sound or just low-cut filter, which probably makes the signal slightly less busy?
And I can not estimate the difference using any other way, because the measurements look the same.

What the heck is an .ape file...

Surely if you were buying a headphone amplifier on objective measurements, you would get something like a JDS Element, or something entry level from Schiit?
