Thoughts on a new tube amp for high end rig? The last piece!

Welcoming any thoughts/suggestions on monobloc amp recommendations for the last piece of my second system- BTW doesn't necessarily need to be tube!
Been at this for 35 years or so, had a slew of high end gear through the mill but always interested in others experiences.
I have a VAC Master Pre with phono, TW Raven AC with Raven 10.5 arm (likely to mount either a Air Tight PC1 or ZYX Universe II, tbd), EMM Labs XDS1 v3 through a just fully broken in pair of Wilson Yvette's (which will likely be upgraded to Sasha DAW's later this year). Shunyata Anaconda PC's and Crystal Clear Magnum Opus IC's, WW Plat 6 speak wires. 18x13 room with good sweet spot set up.
Although the PrimaLuna Dialogue Premium mono's/Pre have worked really well as hold overs, I need a pair of mono amps to fill out the frame here.
Been down the ARC road many times over, maybe 160m's would fit the bill but I'm tired of the ARC constant upgrade treadmill, thinking Pass 160.8 may also work if my room were an igloo. VTL MB 450's? VAC 200iq's?
Thanx in advance for any opinions.

I like Yogiboy's suggestion of Quicksilver V4's with KT150 tubes.  A friend has a pair and they are impressive... much better than VAC Phi 200 that I owned for a few years.
