I guess my question is since the RE Audio is only $99 is it a decent amp for the money.I only have $100 to put towards a new amp and was looking at the RE because it seems to be the best cheaper brand I can find.I already have a Xtant 121m and will be purchasing either a Boston Acoustics G215-44 or a Alpine SWS-15D4.Should I keep the Xtant or go for the RE Audio.
