Tube AMP or SS

Orpheus10, When using the standard 8 Ohm power rating, with speakers that have a high impedance, tube amps might sound "bigger stronger and tougher", but with speakers with a low impedance the opposite might be true, where ss amps might sound "bigger stronger and tougher".

I think MA is Monitor Audio. I have no idea if they have tube friendly impedances or not. As Unsound says, it is a matter of matching the amp to speaker and some work better with SS if they need current for low impedances. If your speaker is tube friendly- high and smooth impedance, then I think you would be surpassed how good acoustic jazz can sound with good tube amplifier - much more natural for my tastes.

How do I find out what impedence my speakers are?

MA is short for Monitor Audio which are speaker manufactures.

It might be within the product info packet, or on the back of the speakers. I did a search, but the manufacturer is not exactly completely forthcoming with regard to specs. They quote a 6 Ohm nominal impedance but there is no mention of a minimum impedance, and the frequency response is without +/- dB's. They also quote a sensitivity of 91 dB 1 watt/ 1 meter, and the suggested power range is between 40-175 Watts, but don't mention if that is per channel or total per pair.
Based upon the available specs, it would seem that either ss or tubes might work.
