I have tested all 3 systems at the IAA in Frankfurt last September. HK is really super! But I decided for the Hifi Active as I think this is also a very nice upgrade. The standard system is not bad but I could really hear the difference. I had a limited lease budget so I decided that the Active system was good enough and spent the difference with HK on other options
. You can not have it all...But if you can: take the HK!
