Citation 7.1 CUTS out, do I need More Power?

YOUR CLIPPING, YOU NEED A BIGGER HIGHER CURRENT AMP FOR THE 10T. Read the other post you posted. Your going to damage the 10Ts and your amp by driving them into clipping. Your running out of current.

Both amps, the 7.1 and the low wattage Class A Marantz just do not have the current necessary to play Modonna at high volume levels. For reasonable price Classe has the kind of amps (300w per side into 8ohm and up I would recommend)you need for the 10T. The big Plinius is probably a good amp for the 10T. Beemer has good amps but very expensive. Call Aerial, they will recommend a few amps. The 10T is a pretty nutual speaker. The amps/pre/source/cable/treatment will determine it's final sound. Believe me, the 10T can handle all the power you can throw at it without a bead of sweat. Your going to damage the 10T by underpowering them and pushing your amps past their design limit. The 10T is a pretty hefty price new. The real thing to consider when purchasing them is that its going to cost just as much or more to power them. Like matching Jack with Jill. Specs can be decieving. 450 sounds like plenty of juice but it is the current and ohm load that you need to look at. Many receivers say they produce a gazzillion watts. Come on give us a break, lets get real.
