Try 0 dB or 10 dB.

The answer is subjective.
In real world there is no equipment that will give you 4x better results if you compare two things that are working right. Let's say that amplifier A has noise level that is around -80 dB, then amplifier B (4xbetter) should have -320 dB...
Which is not possible in any case.
Furthermore, below -90 dB - noise is non audible. Some people would give huge amount of money for something that they can't hear at all. Because HIGH number printed on the paper - looks good. And amplifier that is overwhelmed with "high numbers" - "must be good".
"I my garage I have Ferrari that is able to drive almost 200 Mph.
But I live in woods and use John Deere to get to work, because we do not have roads.
Do I need Ferrari?
...No. It is just waste of money.
You are absolutely right !
The other interesting question would be in my opinion, if someone, with great experience in headphone amps, but unfamiliar with the sound of the BCL, could distinguish on a blind test, witch one, the BCL or the Lovely cube is more expensive/better.
i can successfully distinguish and identify different amp and headphone combos in a blind test.
i know what headphone/amp i am using as well as being able to hear and identify the different tube combos/cables/mods/etc used in the system.
i am THAT good.
Who are you to say how someone should spent the fruit of their own labour?
