What amp to match with Spatial Audio M3 Sapphire open back speakers


Fellow audiogoners,
If all goes well, I will shortly be the proud owner of a lightly used pair of Spatial Audio M3 Sapphire open back speakers.
The trouble is that in making this acquisition, I will have expanded most of my intended "hobbies" budget,yet still need to purchase an amplifier that will make the speakers sing.
The rest of my modest setup consists of: Bluesound Node 2i streamer, SMSL SU-8 V2 DAC, ProJect Debut Carbon Esprit TT.
The listening room is our living/dining room (400 sqft), and our music ranges from classical to world, with a good dose of classic rock and jazz of all types. We also like to turn things up from time to time...to dance!
Sound characteristics I appreciate the most are: musicality, definition but not too clinical, wide and open sound stage, tight impactful bass, and most realistic vocals. 

I am thus calling on all Spatial Audio M3 owners and others to request your advice/guidance in helping me select an integrated amplifier at a budget of around $2500.
Thanks very much for your input and experiences, have a nice weekend and please stay safe!jlr261

Honestly. Until you get the speakers in your own room should you even start to consider what the best amp might be? Not a living soul could tell you that. The M3 Sapphires are very efficient so really you need 50-60 watts, even less with tubes in the transformers are well made. I use a 400 watt, McIntosh, on mine set. The speakers are very open and unboxed like in every way. Fast as stats and very clean bass, no one note booming bass. Stand up bass sounds light and fast just like the real thing does, unlike a box speakers certain bass notes don't all of a sudden become loud or boomy. Every enjoyable, once you learn the speaker and take the time to set them upright, one of the easiest as far as balance left to right, like a box speakers pulling them out from the front wall, is a good thing, no different, 36" works fine, even several inch's less may be depending on your room. Toes in starts crossing you in front of them toe them back 1/2 inch at a time till you lock the image in and balance top to bottom. 
I should have added if you have a tube amp or a McIntosh tube or solid-state amp the 2,4,8-ohm outputs, the 4-ohm outputs make the Sapphire M3's sing like no other. The 8-ohm tap sounds louder, but it throws off the wonderful balance tone of the speakers. Using the 4 Ohm tape you just have to raise your volume on the preamp a bit more, and you will also find you have more control over the volume level. With 8 ohms the M3's sound good, with 4 ohms exceptional.
