Integrated amplifiers — Line Magnetic AS-125PP 211

The AS-125PP 211 is a tube mono integrated amplifier from Line Magnetic, sharing chassis dimensions with the brand's AS-125N while delivering substantially greater output power built around the celebrated 211 output tube. The AS-125PP 211 brings Line Magnetic's considered tube-circuit engineering to a dedicated monoblock format.

Key specs that matter

One balanced XLR input and four single-ended RCA inputs are provided. Input sensitivity is 500mV or 14mV depending on connection. Input impedance is 100k ohms balanced or 600 ohms single-ended. Output power is 60W per channel - considerably more than the AS-125N's 18W figure. Gain offers a switchable 51dB or 63dB setting. Signal-to-noise ratio is 88dB. At 480 x 275 x 490mm and 43kg, the AS-125PP 211 shares chassis dimensions with the AS-125N despite the considerably different internal circuit topology.

Sound and use context

Expect the rich, harmonically saturated tonal character 211-tube-based amplifier designs are broadly prized for, with the substantially greater 60W output providing genuine dynamic headroom well beyond many rival tube designs.

Pairing

The comprehensive five-input connectivity comfortably accommodates a source-rich system, and the substantial 60W output suits a wider range of loudspeaker sensitivities than more modest tube amplifiers.

Alternatives

Line Magnetic's own AS-125N shares chassis dimensions at considerably more modest output, worth considering instead if the AS-125PP 211's substantial power exceeds what a specific loudspeaker requires.
