Temporal blur – You won't be getting any with Alberto Guerra's Tempo [$5'500], a compact 100/200wpc into 8/4Ω GanFet stereo amp bridgeable to twice the power. Based on the circuitry of his award-winning AGD Productions Vivace just without packaging his switching circuit inside a tube's glass bottle, the fast-switching class D Tempo measures all of 11 x 3.75 x 6.1" WxHxD and weighs just 10lbs. Its pulse-width modulation frequency is a high ~600kHz, input impedance 40kΩ, voltage gain 23dB. Finishing of the machined aluminium enclosure is silver or black, high-gloss polish extra. Like the 'tube'-fitted amplifier models, Tempo's power module is swappable should next-gen improvements become available. No built-in obsolescence here.
