Suggestions for power amps

wider soundstage maybe more lifelike energy, little more low end kick

If you can accommodate them, adding a couple subs may be the most cost effective and effective way to achieve what you’re looking for.  A pair of SVS SB1000 Pro subs only cost about $1100, and they offer a generous 45-day risk free trial including shipping both ways so why not?

But if that’s not feasible I’d look at this Pass Labs XA25 that should give you a lot of what you’re looking for…

Just a couple ideas, and best of luck.

I'm at an impass too... have Audio Note AN-e/sp, Aesthetix Calypso Sig paired with a Canary M-90 300b power amp. It's really very good but always wondering about amps. I'm all in on my pre & speakers and have enjoyed an all-tube setup (even DAC) for a long time now. Did really enjoy a Chord, SPM 600 in this same setup at one point but wondering who's had a kit anything like this and what they found to be a winning combo, and why.

If you haven't tried adding a sub, I would recommend it.  A good one should expand the soundstage and fill the room with sound.

Schiit Tyrs?

With Pass X25  for solid state this is an amazing amp.For tubes My friend likes Aric amp.
