To me, Breverb sounds "metalic"...that's just me...
it's a nice reverb...but it doesn't suit me...
I have CSR, Breeze, IR-L, Trueverb, Breverb, TSAR-1R, RennVerb, PerfectSpace, blah blah blah..
CSR is quite nice but requires a lot of tweaking to get where it should be...
Breeze has loads of presets that are nice right out of the gate and require minor tweaking..
IR-L, with the right IR is nice, but Convo's tend to be resource heavy, Breverb is too metallic for
my taste, TSAR-1R is nice - simple controls, RennVerb is ok, PS, for coming with Sonar is a decent Convo...
It all boils down to taste and what you're trying to accomplish. I'm sure that IR-Live will yield
quite acceptable results...
Waves has an entire Library of IR's here..
http://www.acoustics.net/ The Plate 140 is nice...as is the LX-48L
But, as I said, a Convo Reverb can be quite CPU unfriendly...
since I don't see any specs for your system...just be advised...
