@onehorsepony, trying the speakers at home is not a bad idea. We use to bring the speakers to the person's home, set them up and picked them up a few days later.
Personally, I think you are going sideways. Put the money into a cookie jar and save a bit longer to make a bigger jump. Your amplifiers are not bad at all and will drive just about anything. Improving your speakers will make a more noticeable improvement in sound quality. Also it is always important to know what loudspeaker you are driving before you buy an amp as this is the most significant synergistic decision in the entire system next being cartridge for tonearm.
