When I was considering the Totem Mani-2 signitures, the dealer repeatedly told me to make sure I have a quality system that can make the Mani-2 bloom.
The Mani-2 is one of the toughest Totem loudspeakers for amps to drive. It has a low impedance (4ohms average and probably dips down to 2ohms at some frequencies) and only 85dB/W/m sensitivity.
I would NOT recommend you buy these speakers for your Maven amp without trying the combination first. I'd recommend at least a high quality solid state power amplifier w/ 200wpc and the ability to deliver high current into low impedances.
Totem Acoustic loves to demo their loudspeakers with Sim Audio equipment, so that'd be a good place to start if you decide to switch your amplifier.
I personally love McIntosh power amplifiers which can easily handle the lowest impedances without sweating. My Totem Hawk loudspeakers are mated w/ a 300wpc McIntosh MC7300 power amp and they make fantastic music together.
Hope this helped. Good luck,
