Yes, the levels can be matched fairly exactly. Much more accurately than your ears can detect. It depends on how accurate your meter is but really any decent meter these days can measure accurately to small parts of a volt. So you need a AC volts meter preferably RMS, test leads (Preferably alligator clips or some form of clips.) plus a PC for a source and a oscillator that you can find here set @~ 300Hz like I set this one to be for you @ 50% volume.
I'm happy to share this info I just discovered in the last 2 days. LA90 rear panel has a "Bypass" mini slide switch which bypasses the volume control like a so-called "HT Bypass" or if you're older (cough, cough) the proverbial "Main Amp" input. (Some recall integrated amps with two vertical RCA pre-outs (typically L/up, R/down) next to matching "Main Amp" RCA inputs with 2 U-shaped horizontal shorting jumpers connecting the L/R pairs.)
On the subject of how much power is enough I suggest the following, presuming the magnitude of power is suspect, in the gray zone, not on the extreme ends of the curve. Each person can and may have a unique answer to this Q. There are simply too many variables for anyone to answer accurately for someone else.
Given the use of the regulated power supply and near-identical numbers between "max power" and "peak power' measurements, I suspect the LA90 would perform more like a Class D amplifier than a traditional Class AB amp in regard to its performance when you're pushing it to the red line.
That is a great point. LA90 is a Class AB amp based on a chip/IC with bipolar output section. But when "push comes to shove" as my Italian-American friend in San Francisco used to say, it may well distort more like a Class D amp.
That is beyond my level of expertise. Perhaps someone else can opine.
Have you done any of these comparisons blind? What speakers are you using? You've mentioned it's a very small space - have you done any room treatment? How close to the walls are your speakers?
Active monitors are mend to be used in well treated environments to shine,a small bedroom is usually not such a place.
Many modern active monitors include DSP for room correction, or at the very least contain various roll-off settings to compensate for placement near a wall or for room modes. They tend to sound much better in a small space when sitting close than do passive speakers in a similar price range.
You're right about it but what I'm trying to say is that in such environment (a relaxed bedroom) where critical listening is not the goal I would keep the cost the absolute minimum.
But that is clearly not what the person I was responding to is doing.
Are we both talking about the person with the 9 m² bedroom or I have missed a post?
Yes the person with the 9m2 bedroom who spent over $1,000 on multiple amplifiers chasing some kind of hi-fi sound.
Ok then,we probably try the same thing,reduce cost.
For your specific use case, consider this speaker - it may fit the bill: https://www.amazon.ca/IK-Multimedia-Studio-Monitor-IP-ILOUD-MTM/dp/B07NC6KFL8/ref=sr_1_1_sspaSokel

Thank you for advise to try an active monitors. I thought about this. Unfortunately, I never heard on Hi-Fi exhibitions small speakers acceptable for "big scale" music on extreme low volume (for sleeping). Maybe in future I'll find something good
Also I don't use any computer equalizer or special room correction (but I have a carpets in my bedroom). I like "Direct mode" sound
If someone used to listen good music with good equipment, he wouldn’t like anything less than perfect, even in small bedroom. Totally agree)Sokel
