I'm currently awaiting delivery of my Model S P100D with the UHFS option. Unfortunately, after hearing complaints about the sound quality of the UHFS package from so many owners, I want to explore alternatives. I would like all audiophiles out there to chime in and provide the best aftermarket system for the model S for a budget under $5K. I recently listened to the Burmester High-End 3D Surround Sound system in a Mercedes Benz S class and I was blown away. I must confess that I came very close to ordering the Light Harmonics S.12P yesterday, but I after reading through 59 pages of this thread Vendor - Premium Audio System for Tesla Model S by Light Harmonic, I had some serious concerns due to the following reasons: Unreliable amplifier - The amplifier kept failing for some people and they had to send it back. This is a deal breaker for me as I would not want to go through the pain of removing the amp every time it fails. Mediocre Sub included in bundle - There were complaints that the LM sub is worse than the stock sub. However, this is not a deal breaker because some folks reported great success with the SOUNDQUBED HDS-208 sub which I could also get. Lack of customer service - Light Harmonics appears to be very unresponsive to customers' inquiries. This is not a deal breaker provided that the product is very reliable. I also heard great things about Reus, but I did not see any details about what they would install. Since they're not based in the DC metro area, the wait time for their engineer to fly to DC can be quite long i.e. it can take months. To all audiophiles, please weigh in and provide your recommendation.
