I went to my local dealer today during lunch. I took a CD with me that had both great high and powerful lows. They had 2 323i's on the lot, one with the factory stereo, the other with the HK upgrade.
Here is my summary:
You can tell a difference between the two systems. Though the margin between them is minimal. I think this is because the stock system is so good. The HK upgrade sounds great, compared to a crappy stock system it probably sounds absolutely wonderful, but compared to the stock E46 system it does not flurish as much. Before I did today's comparison I was set on including the HK upgrade in my order. Though today, I'm thinking a little differently. If the HK upgrade was only $200-300 then it be well worth it. But at $675, I strongly contest, it is not worth it.
Now, someone early mentioned replacing the amp in the HK upgrade. If this works, that would be great, but why put another $300-400 in a system that already cost you almost $700.
All other opinions regarding the replacement amp are appreciated. Also, has anyone upgraded their stock system and if so with what and what was the result.
