"Yes on amp watts quality , regardless thou, if you require 200-300 watts for unclipped reproduction , the 45 watts is clip city ...
I run a couple of Class A amps that put out less than 100 watts into 8 ohms. They drive the hell out of the worst loads out there. When I bought them, they were driving Apogee Scintillas at 1 ohm setting (efficiency ~ 73 db) and drove the hell out of them. The reason is that they have very robust power supply circuitry and keep doubling down as you halve the impedance. They put out very high current - the Scintillas need up to 60 amps on music peaks.
The point is that simple output numbers don't tell the whole story - that 45 watt amp you look at may pump out several hundred into low impedance loads.
Some amps - Krells, Classe DR3 VHC, one model of Eectrocompaniet, an early Bedini, the rare Belles A, and one of the Adcoms were about it for the Scintillas.
Of my 3 systems, I have 4 power ams that will drive a Scintilla, and in my other one, a Class A/B amp (Rowland 5) that likely will but I've never tried it (150 watts into 8 ohms, 475 into 2 ohms

Could you list the names of the 4 other amps you have tried on your Scinnie .....

"Could you list the names of the 4 other amps you have tried on your Scinnie ....."I aid I had 4 amps that would run a Scintilla (and in fact a pair of them were doing so when I bought them) not that I currently own Scintillas - though I'd be tempted if I found a pair in good shape.
I run a pair of bridged Classe DR3 VHC to drive some Vandersteen 4As and another stereo VHC to run Martin Logan CLS (original version).
I use a Class AB amp, albeit one with considerable power supply (150 w into 8 ohms, 475 into 2 ohms), a Rowland 5, in the main system to drive some Wilson speakers.
I also own a Belles A not currently in use (recall that they made a hundred and something of them)

Agree Bill ,Then You are not using a 45 watt amplifier , especially @1 ohm , same as the 8ohm rated amp at 100watts , that amp would be able to do 600-800 at 1 ohm and yes PSU is very important since your speakers are practically connected to it....
My point , you aren't doing it with 45 watts when the amp is capable of doubling down on a low Z speaker, at that point it is no longer a 45 watt amp ..
BTW , bass drivers work best with high voltage , so high powered amplifiers are best, as low output (voltage) amplifiers will not grip or drive the bass as well , even when operating at the same power level ...
