I missed this. Would explain why people don't like the sound. Was the M3 running with open valves? Doesn't sound like it. I think even the M3 wouldn't sound as good with the valves open as well.

No reason why the 1M should sound like a 'fart can' as some are saying, unless that is what you are going for. For comparison, here is mine with the Eisenmann Sport. Also plenty of 1M owners with the Akra system and is seems to sound better than what is represented here.
