” The enormous soundstage recreated here allows images to spread and individualise in all the perspectives; there’s a sense of gravitas to the music that commands the listener’s attention. This sonic weight is aided by the 800’s command of the low registers. Our speakers are a tough impedance load, in the 80Hz-100Hz range especially, but the 800 just held tight. No matter the bass content the amp reproduced it with phenomenal depth, punch, detail and rhythmic flow. And again, those scary transient attacks provided an entertaining and exciting factor to well-recorded rock.”

” After matching levels between my two different Nu-Vista 800 setups—with a line-level source driving its balanced inputs, and with the outputs of my darTZeel preamp driving its single-ended inputs—switching between them revealed, in the latter, a very slight diminution in bass definition (but not extension), and a barely perceptible softening of high-frequency transients (so slight as to probably not be noticeable to most listeners). While the latter would be beneficial to an overanalytical component that made transients too sharp and defined on top and overdamped on the bottom, they weren’t at all what the Nu-Vista 800 needed. Therefore, I did all of my listening to digital recordings through the Nu-Vista 800’s balanced input, with the DAC’s analog outputs directly feeding the amplifier”
