It is a banaid fix because his AMR has to drive the input of a preamp through the same interconnects and pre amp inputs are usually 47kohm (industrie standard), his FL100 is acually higher and easier to drive at 57kohm through the same interconnect and 1 pair less as well.
And gain doesn't even come into it as he has an abundance. and as a bonus it's all direct coupled, no "masking" capacitors in the signal path as it would be with many preamps.
A preamp in this case in the path can only add colouration/distortions that some may like because it's masking a problem elsewhere.
Like I said Nelson Pass's quote says it all, to contradict it is almost blasphemous. read again carefully.

A Quote from the master Nelson Pass
We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more.
Think of it this way: If you are running your volume control down around 9 o’clock, you are actually throwing away signal level so that a subsequent gain stage can make it back up.
Routinely DIYers opt to make themselves a “passive preamp” - just an input selector and a volume control.
What could be better? Hardly any noise or distortion added by these simple passive parts. No feedback, no worrying about what type of capacitors – just musical perfection.
And yet there are guys out there who don’t care for the result. “It sucks the life out of the music”, is a commonly heard refrain (really - I’m being serious here!). Maybe they are reacting psychologically to the need to turn the volume control up compared to an active preamp.
