Whether the stainless steel and gold finish meets your requirements is a matter of taste, but other finishes are available, and sound quality is genuinely natural and organic

Although distributed through the same channel that bought you Magnum, Token Audio is an independent brand, designed and manufactured by Principia of Cambridge, headed by one Kelvin Newton (geddit?). The products are generally a little more affordable than Magnum, and although the K50 amplifier tested here is the most costly in this month's group at £345 with a stainless steel finish and gold plated control knobs, it can be bought for just £299 in a more utilitarian black suit of clothes. There's even a half way house version with a black carcass and a stainless steel facia at (you guessed it) £325. For a small volume amplifier from a specialist brand, these prices seem almost too low.

Notwithstanding a rather stiff input selector and a mains on/off switch apparently straight from the RS catalogue which is really a match for the rest of the front panel furniture, the test amplifier looked good and handled well. Our favourite feature is the Token badge with a reversed K motif, mirrored incidentally on the pair of gloves thoughtfully provided to help avoid fingermarks when handling.

Rated at a minimum of 50 Watts per channel into eight Ohms and 80 Watts into four, the K50 is a minimum features straight-line amplifier with no tone controls or other audio signal path impediments other than source selection, tape monitor switches and a volume control. Additional socketry described as an auxiliary output is in fact a preamp output taken from after the volume control - there is no input buffer or gain in the preamplifier - which can be used in conjunction with another K50 whose volume control is set to full gain in a bi-amplified system.

The amplifier is bipolar, with 'very low' feedback, whose circuit is contained on a single PCB, with a minimum of hard wiring, star earthing and a leavening of 'selected' passive components.

Sound quality

The K50 acquitted itself well in two presentations to the panel, with extremely consistent scoring between listeners, and between sessions. "Very clear, informative, detailed and dramatic" wrote one panellist of the percussion piece, and of the Friend and Fellow track he described this amp as "possibly the clearest amp yet", though he felt the vocals "could be warmer and friendlier", a judgement that presupposes the track has this quality to start with, which is arguable. Another described the Beethoven piano sound as "comfortable and mellow, with good scale and weight, but lacking a little air", and most of the other comments were in the same ballpark. The average test panel score was a good indication that this was one amplifier that emerged from the test smelling of roses.

The hands-on listening painted a picture of an amplifier that was naturally distanced, with a smooth, unprocessed quality, though dynamics were not particularly, and there was comparatively little adrenaline in the music. The tonal balance is notably warm, but the overall prognosis has to be favourable, in part because it is so lacking in the usual transistory cues that the test systems built around it tended to sound very believable.

Conclusion

This is a quality minimum features amp that differs from others of its type thanks in part to surprisingly reasonable pricing. It is not the most powerful or dynamic amplifier around, and detail resolution is only fair, but transparency is first rate, and despite some tonal anomalies this is an amplifier that doesn't get in the way. Recommended.
