Absolutely astounding plugin. This thing looks pretty and sounds like a dream. I don't feel jealous of expensive hardware units anymore. The reverbs from this piece of software are lush, rich and really dream-like in many cases. Placed a random hall preset on a piano and instantly there was new life in what would otherwise be just a "good" sounding piano (which was now mind-blowingly superb). I don't think I could say enough about the sound. I can't imagine any instrument sounding bad with a touch of this behind it.

CPU usage is also BEYOND low. Uses %1 per instance on my Q6600 (quad-core). Phenomenal and seems very stable. Probably one of the best purchases I've made in a very long while. VERY pleased.

All-in-all this plug-in is bomb-proof. Sound is exactly what I've been looking for and CPU drain is next to nothing. I can't see anything negative here.

I tried a lot of reverb plugins for PC but never found something what sounds good and has low CPU usage.
Now I own Breverb, native reverb plugin with exceptional ratio between sound quality and CPU usage.

As I said, the sound quality and CPU usage is excelent but I can not say the same about user interface which seems to be the weakness of this baby mainly the work with presets is sometimes very confusing because of small place for presets handling and reset of preset window everytime I close the plugin window. The small stereo width faders are also not the best solution. Other things are OK.
The positive difference against its competitors is that you never heard clicks and drops while changing the presets and values. Everything works like a charm.

Sound quality is very subjective thing. For me the sound of Breverb is impressive and you will never believe how fine reverb processor can sound with that low CPU consumption. The overal sound is crystal clear with big depth and uncolored tail. This crystality sometimes evokes a little bit digital feeling.
There are 4 different algos: HALL, PLATE, ROOM and INVERSE
All of them are on the same quality level and highly useful and all of them are fully editable in all possible and impossible parameters.

Customer support is excelent. I got right answer via mail in 10 minutes :)

I use Breverb more than month under Ableton Live without any crash or indication of instability.
