On the other hand, energetic rock and suchlike is great. Specifically, it has a touch of brightness that affects voices, particularly the consonants and doesn’t always have quite a bass reach of the best in this group. This turns out to be another amplifier that’s good at exciting, energetic music-making, though our listening panel did feel at times that it’s, perhaps, a bit too much of a good thing on the excitement front and could do with relaxing a bit. The phono stage handles MM and MC cartridges, though you have to get inside and fiddle with jumpers to change settings. There is a preamp output, which is also applicable to bi-amping and a record output marked ‘Monitor’.

Please change to countersunk screws, at least!Īpart from the phono stage, input provision is basic and there are no modern frills like mini-jack sockets for portable players etc. That means you’ll have less cause to use the rather gorgeous remote, made of solid wood with a metal top plate – but also less cause to lament the ugly cheesehead screws which hold it together from the top.

The latter is motorised, but input selection is not remote controllable. Uniquely in this group, input switching is done by a mechanical switch, mounted at the rear and operated by a long rod from the front panel – volume control also uses a regular mechanical potentiometer.

There’s very little use of surface-mount parts and most of the amplifying is done with discrete components, though there are a few op-amps dotted around and also some integrated circuits with part numbers intriguingly obliterated.Ī substantial mains transformer is used and there is plenty of smoothing capacitance, plus quite extensive regulation of supply voltages for small-signal stages. One of those was provided for review (the price given includes it, a very reasonable £125 on top of the basic model).Īll kinds of amplifying devices are found inside the case, as the circuit uses bipolar transistors, FETs and valves. An exciting, energetic music-maker with a handy phono stage optionĪ large and imposing amp, this one is also pretty bare-bones, though unlike most it has the option of a phono stage.
