If you care about soundstage you may consider VTL MB450 used.

I had been using only tube power amp except driving subwoofer for last 20 years.

I had been happy with Line Magnetic 508 for last 3 years but it may not have enough power to drive your speaker.
There’s a pair of McCormack DNA1 monoblocks with Steve’s Ultra Platinum upgrades for $3500 on US AudioMart.  Pretty darn close to perfect IMHO. 
@soix McCormack is some mighty fine gear, serviceable, reliable, 
mable to call,and talk with the Steve himself!

 But he Sanders Magtech is beyond even Steve’s amps.

mplease call, talk, with Roger Sanders, he will,blow your mind.

there is really no amp which will give you the headroom, sound, and longevity of the Magtech!!

look into it!!

 You will thank me in the long run!
