Experiences with BACCH4Mac software?

I heard the effect of this software at Axpona and was totally blown away, no question.  They have a variety of offerings, but the subject software is the only one that would fit in my budget.  I stream digital music via Audirvana from my newish iMac with my recorded music on an HDD.  I have heard that this budget version for the iMac is rather hit and miss.  Can anyone chime in with experience with this software?  If it works like I heard at Axpona and isn't too complicated to set up, they will get my $980 very quickly.
