He didn't need to ask twice. Goller is a psychacoustician and former head of driver design at Vifa, ScanSpeak, and Skanning, and the designer of the symmetric drive (SD) and non-resonant chamber (NRC) drivers, among many, many others. The chance to get a data dump from the driver guru was irresistible.
The house was everything Stephen claimed it was, except for one tiny detail: the only place to set the speakers up in the 5000 square foot open plan living room was smack dab in front of the pool table. Goller rose to the challenge, however, and placed his L7 floorstanders ($14,900/pair) 15' apart and sat me on a high stool about 23' in front of them. Driven by an all GamuT system—CD3 CD player ($6000), D3 preamplifier ($6100), and M230 230W power amps ($11,500/pair)—the speakers create a cohesive soundstage in that vast room. They sounded intimate, putting Donovan between the speakers and awfully close to life size. On Strauss' "Banditen Galop," they filled the room with an orchestra and reproduced the whip-crack percussion with scary transient response. The system was fast, bold, and uncolored.
I've asked Goller for a longer interview for an upcoming eNewsletter—spending time with him was way too cool not to share. Ditto, the new GamuT products.
