High End by Oz and United Home Audio joined together to present the US premiere of Vitus Audio’s SIA-030 30W class-A/200W class-AB integrated amplifier ($40,000) and AudioSolutions Virtuoso M loudspeakers ($32,000/pair). The speakers, which weigh 165lb each, claim a sensitivity of 92dB, 4 ohms nominal impedance, and an in-room frequency response of 25Hz–30kHz. Together with Vitus Audio’s SCD-025 MKII CD player/DAC ($25,200), United Home Audio’s Ultima 4 OPS-DC tape deck ($30,000), and Ansuz Acoustics cabling, this system was playing an interesting and unusual selection of music, including the Vivace from Britten’s Violin Concerto, performed by Linus Roth. Bass was excellent. I made a mental note to hear these components again in a more conducive setting.
