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 ?

Get a pair of subs to fill in the sound stage. Makes a big difference at low or higher volume levels.

What you need is an integrated with loudness control, for low level listening and still get the punch. Accuphase, Luxman and/or Yamaha would do.

These speakers appear to be bi-wireable. Bi-amp them, if possible. The majority of the listening here is around the same dB. If you happen to have another amp available, hook it up. The results may be surprising.

At 60 db liwstening level , you are only using less than 20 watts ...if that.
He said:

So 1 W would make 86 dB. maybe they are 3 meters away so they drop to 76 dB and add in the second speaker and they are at 79dB.
That is still 10 dB higher than “somewhere in the 60 dB range”, so he is arguably using closer to 1/10W.So I am failing to see how sensitivity or [power is what the OP needs?


However this is a good point:

4 Ohm and 86db. 
 Get an amp that is reliable and stable into a 4Ohm load, which has a solid power supply and will give you a good 300-400WPC into A 4 Ohm load. 
My opinion and experience.
