I currently own a First Sound Presence Deluxe Mark II Statement with Paramount Plus upgrade. Now that's a mouthful. It is a four chassis unit with separate left and right channels and power supplies. The First Sound is amazing. My best friend and I have been chasing high end equipment for about ten years, never quite being totally satisfied, and spending enormous amounts of money to keep trying to upgrade. Well I can tell you with this preamp, I am totally satisfied. My friend and I are in awe of this thing. It has such a low noise floor, which in turn creates a dead silent background. The decay on notes is unbelievable. I could go on and on. It is the very best piece of audio equipment I have ever purchased, and I own or have owned a lot of very nice equipment. I currently own Alon Lotus SE Signature speakers, and am waiting on a brand new pair of Nola References to be shipped to me as I write this. The similarities in speakers and possibly preamps is what made me respond. I use a VAC Renaissance 30/70 amplifier. One final thing, Mr Go is the most enthusiastic, helpful, enjoyable person I have ever spoken to about high end audio equipment. He is one of the most down to earth and nicest persons in high end. It feels good to own a piece of his equipment, because he truly cares. He has pride in it, and you can tell by the way it is built and the way it sounds. It is the only thing this guy does. Preamps. Period. I also have much respect for Kevin Hayes of VAC and Dennis Had of Cary. But they do make a lot of different pieces of equipment. A lot of different amps and preamps. Mr Go is perfecting the one thing he knows best. You can also continually upgrade that preamp, which is also really nice. Give him a call at 425-271-7486 and just talk to him about his preamps. You will be impressed with him, I can guarantee you that.
