the EQ hater note wasn't about you(nor Joe obviously), you love your EQ as much as we do(even if we do for different uses). ^_^
your bluetooth headphone receives digital signal, so whatever you use upstream, it will still come down to the loudest amplitude being sent to the headphone's DAC as being 0db and no higher. so no number of DAC to amp to adc to headphone's DAC will help going louder. the problem is your BT headphone not having a higher max voltage.
by default a song that reaches 0db and has very compressed music(no dynamic), will almost entirely sound like it's around 0db and it is, so it will feel loud.
now with a very dynamic classical music, with loud passages, quiet passages etc. if the loudest sounds are near 0db, the rest of the music can still be 10 or 15db lower for the quieter passages or instruments(+10db feels twice as loud). so overall that classical track will feel like it's a good deal quieter compared to the low dynamic song before, when both could reach 0db peaks.
any replay gain solutions care about the overall dynamic of the song, instead of looking only at the highest value the peaks are reaching. if the target is 89db and the song has very compressed dynamic, then almost all the song will end up at around 89db. while the classical song might not be touched at all to prevent clipping, so now you feel like both songs sound as loud. but in reality the overly compressed one was made to play quieter to fit the dynamic one.
and as I said several post above, if you look for sound quality, then you want to avoid clipping and avoid having the limiter to activate as much as possible. because they are both not totally transparent solutions as you noticed.
about what you're asking for from the start, I don't know that it exist on foobar(but I'm not expert) there probably is a VST that does just that somewhere on the net. the thing is you're asking for peak normalization, and while it's perfectly possible, nobody listening to music would want to use that as a listening default setting. because as I explained for the low dynamic song vs highly dynamic song, you would end up with songs having very wild perceive loudness differences. so very annoying in the long run. the only reason why we use replay gain, mp3gain ,R128... in the first place is so that musics don't have too much perceived loudness disparities. so even if you find what you're asking for, I'm not sure how you would like it.
