The Trinnov has completely changed my listening experience in my professional studio for the better. Mix translation is 100% the name of the game, and the trinnov has made it easier to trust and produce professional level mixes that I know will translate to any environment.

We had a new room built that was unfortunately not designed very well. The room was not symetrical, smallish, there were so many challenges. I utilized Gik to provide a soultion for treatment, which helped tremendously but I still had issues especially in the low end building up and masking. Running out of space for more treatment, I looked for other solutions. A popular software based treatment was tried which also helped but I kept hearing issues, though it was way better with than without. I then turned to VK and talked to Josh my rep, who mentioned Trinnov. I remembered a ProtTools Expert review on this and that started to ball rolling. All I can say with all honesty it was night and day!! Support has been great with VK and Trinnov, as I have an Avid S6 interface with a Colin Broad TMC 1 S6 controller, I needed to have the Trinnov profiles change with each speaker set via GPIO, the Barefoot’s are now in my room sounding the way they should. Best money invested I have to say. Trinnov helped take the sound of my room out of the equation, so I could make confident creative decisions everyday. It’s a joy to get in to the studio and listen with a smile. Thank you.

Well, I want to do this review, because I want people to hear my experience. I bought a demo unit, and I had a Love hate relationship with the unit, Until I finally reached out to Trinnov and realized a lot of my Advanced settings were messed with. I had never heard the unit. For what it was calibrated to do. Now that it's rocking the way it should, I can honestly say I don't know if I could live without it. Please if you buy a demo unit, take the time to reach out to trinnov or vintage king to get it back to how it's suppose to be. Mine had this weird altercation to the stereo image, and I was just bummed. But trust me, it's amazing. Also making the image extremely flat isn't the best idea. It really makes it hard to mix, your so focused on all the crappy stuff, instead of just making music.. Got the setup working flawless now, absolutely LOVE IT!!! I run it AES in and out of a PURE 2... Couldn't be happier. Thanks vintage king, for carrying the Trinnov, and apologies for my indecisive mind on this, it was some advanced settings changed. So if you buy a demo make sure you have it set back, and trinnov, a master default would be nice!
