MAS Opulance pre

Hi I know you wrote this thread a long time ago,but I noticed that you wrote "I was blown away" by your new purchase.then your next response was that you sold it.Was it not that good after all?
I simply ask because I have recently purchased a MAS Charisma and it seems to be a bit lacking in top end detail and sounds a little bottom heavy.
It could yet be a setup issue.Not Sure,and wondered what was your lasting impressions were.
