Customer Reviews

"My PMCs are so faithful that they force me to be an extreme perfectionist in my work, which I already thought I was. They are so clear and so precise that they have actually helped me to improve the quality of my recordings. They are a pleasure to listen to. "

"The Kray Twinz has always been about forceful, dynamic, bass heavy sound, so I needed monitors that could reproduce that,. My new IB1SA system hasn’t disappointed because it really does have the Wow factor. I’m thrilled with them – they are great! "
