Need advice with matching amp with speakers

It’s hard to go wrong with SF speakers. I’m using a PS Audio BHK Signature preamp and BHK300 amps with mine, but I bought them because they’re “Hybrids” and with a little tube rolling helps refine the sound I wanted to hear. I also have one subwoofer that sometimes gets used, but for the most part, the bass is more than enough for me.

I’m sure you’ll like them with the Michi’s.

All the best.

I think you will find that the Michi will be a good match. The Sonos Faber Is a musical speaker, perhaps at the expense of the last word in well controlled bass and detail. Michi is very transparent, fast, and provides good detail and I suspect you will find it to be a balanced pairing

what do you want help with cos the amplifier is neutral sounding so will impart less than audible character to the speakers. your worry should be speaker/room coupling not amplifier as the amplifier is competent and capable of driving the speaker in question with no sweat @zooropean 

It is really important to identify speakers who’s sound qualities appeal to you, then to verify your amp is up to the task and is sonically compatible. While all components matter... some mater more... and speaker the most. So, you need to identify the sound you like. By far the best is auditioning, while reading reviews (from good professional mags... The Absolution Sound and Stereophile, and HiFi+. This will help you understand the differences between them. B&W are great at a big kick in the bass and lots of treble energy, Focal are very detailed, Sonus Faber very musical and natural sounding, DynAudio are neutral and detailed... there are dozens more. 

First priority, find speakers you love the sound of... then see if any other changes are needed to optimize them.

The listening room size is "average" and cluttered, but that's about to change, so basically, this is a temporary situation. I have a pair of 20-year-old Nordost cables, but I can't remember the model. I listen to a great variety of music types, and regarding the sound qualities, I know I don't like "brightness." Not expecting any specific recommendations because I have too many variables, but thanks for your responses. Should I assume that the specs mentioned above match? 

Hard to make a recommendation since you didn't share anything about the listening room or what sound qualities you prefer.  What type of music do you play? I'm sure you will get some thoughtful responses if the members have the information they need to help.

Excellent speakers that are highly revealing with a tweeter that is described as "incisive",amp is pretty much dead neutral according to reviews,cable choice could tip SQ into slightly analytical/sharp territory so I would look to cables tending to be smooth,slightly warmish like Cardas & bi wiring or good jumpers are recommended instead of the factory jumper bars...
Other speakers that would be a good match would be Spendor,Harbeth or ProAc...
