You are the dealer who specifically said Soulution bass sound like card board and Dartzeel is much superior. You could have said Soulution sounds great but Dartzeel sounds better.
And if that happens to be true? What if Soulution does sound like card board and Dart is way better...
Personally, I would like to know that, particularly if it comes from someone who's ears I trust.
BTW, I have no affiliation with Alma, but I don't like to see people try and squash others opinions because they may (and probably do) have their own vested interest.
You wouldn't happen to own Soulution would you?
