As my P85 is at the Rockville SC for it's annual service I've been driving a P85 loaner for the past two days. This has given me a great opportunity to compare my modified car with the loaner. Several things stand out. First, the sound deadening I did on my car makes it more more quiet on the road. Rear end and tire noise on the loaner is much more noticeable. I also hear the whine from the electric motor as I accelerate in the loaner. In my car I don't hear the motor at all. Bumps also transmit fewer resonant sounds into the car. Second, the stock sound system compared to the Reus is much more harsh, with less tonal range, presence, and clarity. The bass has no depth or punch. To make the comparison fair I plugged my USB drive into the loaner and listened to some tracks I know well: Brahams 3rd and 4th, Chicago I and II, and a few others. The differences in symphonic music, which has a richer array of tonal subtleties than any other type of music, are striking. For example just the difference in the sound of an oboe or piccolo are like night and day. The Reus system is fabulous for capturing these subtleties. To be fair, I don't know if the loaner has the premium sound system, which might account for some of the difference. But it makes me feel very good about the investment I made in the Reus system. I'm very much looking forward to getting my car back tomorrow with all of its goodies BTW, I'm taking a bunch of the SC guys to lunch tomorrow when I pick up my car. Just a small way for showing my gratitude for the great service and care they have provided for the past two years.
