Tempo's sister – From AGD Production comes the Alto [$4'999], a fully balanced DC-coupled compact preamp with built-in MM/MC phono stage, two RCA line-level inputs, one XLR input and 2:1 RCA:XLR outputs (one RCA is an HT thru-put) housed in a milled-from-solid enclosure with Apple remote control and resistor-ladder volume. The op-amp output buffers of sub 50Ω impedance can be customized for an internal hi/lo-pass filter upon request. Measuring all of 20 x 16 x 7.5" WxDxH yet weighing 11lbs, the Alto works on all global AC voltages from 90-264VAC to suggest a switch-mode power supply. Finish options are satin clear anodized or black. The menu selects from 0/180° phase, balance, display brightness and MM or MC. The physical front-panel controls are touch sensors for long life. The form factor is an obvious match for the company's own Tempo di GaN stereo amp.
