Mike: Thanks for the tip. The Porsche's interior is slightly larger and changing its interior is not as critical as our older classic DeLorean. I may go with the Sinfoni amplifier due to the slightly smaller size and it will fit into the DeLorean cabin without major modifications to mount and to hide it. The McIntosh Amp is larger and it cannot be hidden as easily. It will requires major changes to the cabin's interior to have it mounted and to hide it in the DeLorean. Both amps are the same price and both sound quality are audiophile quality (possibly the Sinfoni will edge out a little better in transparency and detail). So, lets see what happens this week as to the direction in the choice of these two amps. Kayo [Non-text portions of this message have been removed]
