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 was kind of interested in seeing if anyone has a firm grasp on what makes for a system that sounds great at low volume. It has puzzled me for a long time. From the answers, it doesn’t sound like anyone else does. I have a fuzzy idea.
I suspect that this @dil fellow might:

Or install an equalizer.


If one had measurements of SPL versus frequency then that could be a start.

I see that this thread has become a hot topic, and I'm happy for that. However I can also see that many people misinterpret  my question or maybe I wasn't clear enough. I never said that i was missing bass or highs at 60dBs SPL. My question was: Will i hear any difference at 60dBs if i get better quality amp with better power supply etc . That means, will I get improved resolution, better clarity, improved soundstage, better imaging, blacker background  etc. 

Also, I do not agree with everyone who claim that speakers with higher sensitivity will sound better at low listening because, at 60dBs sensitivity shouldn't make any difference at all. I think the opposite applies, if I want to listen at let say at 90+ dBs SPL then i will surely benefit from higher sensitivity speakers.

Agreed!

Absolutely yes. Improving components improves the sound at all levels. Your choice of coarse must be a component which has the right character for your listening tastes. Also, while this is crude it has always worked for me, at least a 2x increase in cost… you can adapt the idea to the used market. But anything less is likely to be a lateral move where you will just trade good and bad characteristics. You need to jump a level or two of performance.

Would a Lyngdorf TDAI 1120 work?
