I'm awaiting delivery of my newly purchased Kenwood KA9100 (can't wait!) and am considering a wood case and/or rack handles. Obviously, this is just for aesthetic reasons and I think the look very cool. But, is there a downside to the case when it comes to heating issues? Can it cause overheating due to the fact the amp can't "breathe" as well? Thoughts? Also, picked up a matching tuner KT7300. Really not that into listening to stereo but I just love how the set looks. Kind of why I went with the 7300 rather than spring for the 8300.
