I have set up 3 inputs into my devialets , uncorrected, DIRAC and Trinnov and can instantly flip between them.
Uncorrected is not acceptable at all..end of story..those bass nodes are ridiculous.
anyway to get to the nub of the matter , the correction via dirac enhances imaging and is really great in the bass , albeit the correction can fall down a bit if you do full freq.
When you first hear what the trinnov does you realise you need to change your view on recorded music presentation..the change is jaw dropping , what stands out is the rock solid holographic imagery .. its so seductive .. it enables you to follow every thread in the music and imagine you are there..you can place instruments in 3d space ..clarity and bass improve amazingly especially the bass in depth and pitch definition.
Im not good with descriptions barring to say that I get a more immersive effect and it really not hard to believe that the performers are in front of me....
The correction is configurable so that you can lets say , just correct bass and phase..sounds quite different depending what you do and how you set it up..you can really make your system sound like you want
My pal was over a few days ago and he was playing reggae at crack your ceiling levels and he made a remark that the system doesnt do dub well and with a few tweaks I had him grooving and reaching for his stash
