In the end I know all of that.
Just calming the anxiety man, till the gear arrive :p
like I said I already ordered the BF 27 Gen2, but one thing is true, if after try them, I'm not completly in love, I will sell them for profit and I will seriously consider in step down for something like the Adam's S3X, Focals SM9 or even ATC SCM25A.
thanks for the contributions!
