Is there a such too much power for speakers?

Will over power amplification be crushing imagine, sound-staging and PRAT? Since inner details and dynamics are at peak. 

The thing is, I listen from low to mid Volume level around late nights.

@fundsgon My speakers aren’t too hard to drive, SF Elipsa SE. currently mating with VTL tube amp ST-150, 120wpc. Since I’m now in a bigger room 15’x20’, I need more powerful amp.Bea Lam from VTL suggested between MB-450 (425wpc, $25k) and S-400 (300wpc, $25k)My Local stealership suggested me the more powerful, more expensive, the better which is their flag ship mono block Siegfried (650wpc, $75k).. I knew something wasn’t right. First I don’t have $75k. Second, I ain’t paying $75k 
 Side note: I’ve been eyeing on The next model up from mine, the S-200 (200wpc, $12k) very nice unit but they tend to skip it for the higher ones. 
Any VTL owners want to chime in?
Greatly appreciate 

@erik_squires hi thanks.
i had heard Luxman m900u stereo amp. It wasn’t my cup of tea. I still prefer richness from tube amps.

Hi all, it’s my update.
It’s been a about month, system being freshly put up in the new room, synergy finally arrived and wow I’m finally satisfied with what I already have, the VTL ST-150, 120wpc. .  Dynamic= check
. Soundstage= check
. Imagine= check
. Disappearance= check
. Inner detail= check
. Tuneful bass= check
. Fullness= check
. PRAT= check
. 3D’s= hmm ok
. Toes tapping= check

When synergy arrived last week, I’m not going to lie, I turned off system and walked away many nights thinking that my ears are being programmed or getting used to the new sound or playing tricks with my brain. But it’s been more than a week with many smiles (and smirk) and satisfactions.... it completes me.
Wow, synergy! Took you that long?
Gotta say. I love you man.
