High end high quality int. amp for low level listening

Hello to all Audigon members.  I'm quite in a dilemma weather I should upgrade my amplifier. Currently I own Pathos classic one MK3 driving Sonus Faber Sonetto's speakers, and I must say I'm very happy with sound filling my 35 square meters room. However, it's known that the speakers are power hungry as they rated at 86db sensitivity and 4 ohm impedance and I think they will surely benefit from a bigger power supply. With all that being said I'm not sure if I will hear any improvement mostly because 90% of the time I listen at ~60dBs SPL. My budget is around 5k $ and these are the amplifiers I've been considering:  Hegel H390, Anthem STR, Cambridge Audio Edge A, McIntosh MA5300/MA252, Accuphase e280, Rotel Michi x3 or used Pass Labs INT 25, Mark Levinson 5805.

What do you think guys, will any of the amplifiers make ay difference at 60dB SPL ?

I would also recommend the Luxman 505/507 will do the trick.

I don’t think I would consider changing unless I was going to buy in the $8 - 10K range. At best you will get similar sound, at worst not nearly as good. I

Accuphase! The e-280 should be plenty, or maybe a e-380. The last generation 270/370 is not a lot different. Easiest to find with Japan voltage.

More efficient and higher impedance speakers make a lot more sense than a more powerful amp.

^How^?
At 60 dB they are not stressing the amplifier, and unless that 60dB goes to 80dB SPL, then there is no great reason to add more watts, nor to add more sensitivity.
And if it sound good, then why change anything?

That said the Pass, and some of the others, would be nice to have… but they do not seem to be “required”.
