I have listened to FM Acoustics many years back, and had the privilege of meeting Manuel Huber twice when he conducted audio sessions in Manila. Very nice fellow and can be quite funny too. I have good impressions of his amps and preamps producing good music and I remember over the top of my head, words like 'musical', "smooth" and 'full of body" when I think of the brand, even now. The amp I heard many years ago was very small compared to say, the the Krells, but they pack a wallop in wattage, like what I heard was a 250 watts amp driving a B&W801 S2. I remember the gang was clamoring for some fireworks and the owner gladly put on Telarc's Time Warp by Erich Kunzel, and at the end of the record, everyone was clapping their hands.
Manny Huber himself conducted a demo in a local audiophile's house, and the system was Krell based with a pair of B&W800s and the front end was a Forsell Air Reference turntable and tonearm. Manny brought his own LPs, and the one I couldn't forget was Harry Belafonte's Carnegie Hall LP on RCA. He brought an original. That was the first time I heard the 'depth' of Belafonte's vocal cords, like I can see through down his throat when he sung Cuckooroocucoo....It was an amazing experience. And he let the audience decide for themselves, never uttering any negative words about his competition. Great guy.
But as everyone knows by now, what's not too great is the price.
