Aloha Jerry
I'm a singer/songwriter/recording engineer from Hawaii. I'm the proud owner of two sets of GMA speakers. I have the little Rio's for my recording studio and the flagship Calypso's for my main listening system. I have played music since the late 1960's, and been recording since 1972. I sold high end audio for about a decade, so I've heard a LOT of speakers. For me, the realism of the GMA brand is what keeps me buying them. They don't alter the sonic picture as some speakers do. They don't add 3db of kick you in the chest bass at 120hz or bring your attention to the tweeter. They simply give you whats on the recording without screwing it up like most other speakers do.
Vocal and instrument reproduction are scary real. Just recently, I was comparing the Rio's to the Adams 3 studio monitors another engineer uses. On the GMA speaker, it was easy to hear the drummer hitting the snare in different spots on the skin in a recording recently done. Sometimes in the center, other times closer to the rim. That tells you the drummer is carbon based, and not a drum machine. They allow you to hear the human element...drums played harder and softer...that's real, guitar player picking with emotion, etc. On the Adam's speakers, all this was smeared by the lack of coherency in the time domain. Another poster hear said he didn't know if he could hear the difference between time coherent and non time coherent. Trust me, it's easy. Hearing things like this is critical in the recording process. I think it's critical also to musical enjoyment at home. With the Calypso's, I find it easy to hear, for example, the Joni Mitchell "Blue" album uses different vocal mics on different songs (Confirmed by Steve Hoffman who remastered the album), or that the Acoustic Alchemy album "This way" uses multiple engineers on it. Many people have the Blue album. If you have it, put it on and try to hear different mics. Should be quite easy to hear, If your speakers are smearing that, imagine what else your not hearing. Those are the types of things GMA products allow you to hear. It's a whole new added level of musical enjoyment we never knew existed. I can hear on my own recordings that the guitar is not only a Martin guitar, but MY Martin guitar. You hear much deeper into the recordings. Other studio's have also added GMA speakers with identical results. I cannot say enough good things about them, and suggest if you get a chance to hear them, to do so. Aloha
