Nagra's VPA amplification system consists of two slim, handsome monoblock amplifiers intended for vertical placement. They look good adjacent to the speakers. However, two 845 tubes put out a <I>lot</I> of heat, so the amplifier should be at least a foot away from your speakers...unless you're <I>looking</I> for a nice crackle finish.

Last month (click here for previous Fine Tunes) I tipped you on how to check the AC plug orientation for transformer current leakage—the best sound is often found at the lowest voltmeter reading. Roger Skoff of XLO suggests another technique that's worth passing on to you, if only because the imagery is so . . . piquant: Leave the speaker cables hooked up and pull the interconnects from the power amplifier. Turn it on and "stick your head in the speaker," as Roger puts it, checking for the level of hum. (Imagine a pair of bony audiophile legs waving crazily out of the bell of an Avantgarde Acoustics horn speaker.)
