Here's a more modest system than some of the others featured so far that really nailed the raucous highs on a curious wind version of Revueltas' wild, ritualistic Sensemaya. Veteran high-end designer Frank Van Alstine was justly proud of his Ultra 550 hybrid power amp with its 300Wpc ($2395), Transcendence Eight vacuum-tube preamp ($1299 with optional remote and phono stage), and Insight Solid State DAC ($999). Paired with the Jim Salk Sound Veracity HT3 3-way loudspeakers with their 10" woofer ($4895), this system was making sounds worth checking out. "
Hey, Frank, what's with the 300wpc power spec on the Ultra 550? Your website indicates 250wpc into 8 ohms. The pic shows what must be an old prototype of alternative power amp face plates. Can you confirm this and whether or not these are available on new amp purchases? Anyway, the Stereophile text is quite complimentary on the overall sound quality when paired with the Salk speakers. Man, your vehicle must have been REALLY loaded down with all that gear! Your setup looks really nice. Great work!
