The Classic 62 (£4,895) is about as simple as an ultra-linear tube amp gets, bringing all the traditional virtues – including its ‘traditional’ EL34 output tubes – to the musical party. Small enough to accommodate, powerful enough to run real speakers, it’s no surprise that the combination of dynamic and rhythmic integrity with the sense of colour and presence the topology delivers have made the push-pull, stereo chassis a staple in the UK market. Even so, there are situations where 60 Watts just won’t actually cut it – for which c-j, in time honoured fashion, have added a second pair of output tubes per side to create the Classic 120 (£8,995). So far so good and also, so very familiar: Where c-j deviates from the norm is in their development of refined versions of each basic design. Witness the TEA 2 phono-stage, available in no-fewer than three outwardly identical versions, each sporting identical circuit topologies, but separated by the choice and quality of the components used, the performance delivered, and the price asked. This ability to apply the experience gained with esoteric componentry and the knowledge of how it works in concert, to wring the subtle, incremental, but musically all-important benefits from an existing circuit has become the c-j party piece. The clearly defined musical and sonic performance benefits that attend each level of componentry when applied to the TEA 2 is both impressive and brooks no argument, the SE and MAX variations more than justifying their elevated costs.

Which brings us back to these current, Classic amps – and the decision to jump straight to the SE versions. Experience shows that, as practical and effective as the standard models are, the SEs bring that special something to proceedings. They also bring a scattering of c-j’s proprietary Teflon capacitors, deployed at strategic points throughout the circuit and a change of output tube, from EL34 to KT120. In theory, the bigger bottles should (could) provide more power, although c-j rate both the standard and SE models the same. It should also be noted that this is no straight swap, as the KT120 demands significantly higher supply voltages and draws a lot more current. However, what the switch to the KT120 does deliver is more headroom and greater control at frequency extremes. The EL34, long-loved for its glorious mid-band is beginning to show its age when confronted with modern, wide bandwidth loudspeakers – of which more later.

Hook up the Classic 62SE and the sound is as familiar as the amp’s appearance. Connection couldn’t be simpler, with the sole complication being the need for an unusually long and slender flat-bladed screwdriver to release the tube-cage in order to install the valves. That aside, with the amp biased and warmed through, you’ll be ready to enjoy some classic c-j sound. As I’ve already suggested, ultra-linear tube amps deliver a winning musical combination of musical presence and well-directed power that belies their rated output, leading to the old ‘tube-Watts-versus-solid-state-Watts’ argument. In truth, a Watt is, de facto, a Watt – but the vacuum-tube’s ability to deliver voltage means that it seems to achieve more with its Watts than its silicon-infested brethren. The Classic 62 is no exception to this rule, with an immediately pleasing sense of musical body, pace, and life. But c-j also bring their own special sauce to the standard ultra-linear recipe, adding a healthy dollop of tonal sophistication, harmonic development, instrumental texture, and a well-developed sense of acoustic space.

Like I said, everything’s different – everything stays the same, with the Classic 62SE instantly recognisable as a c-j amp, yet adding its own extension to the established set of musical attributes. With more focus, transparency, texture, and attack, the 62SE sounds like a grown up Classic 60, with more confidence and a firmer tread. It’s an impressive performer at the price – but it is also an amp that majors on subtlety and finesse, qualities that demand careful matching if you are to reveal and enjoy their full extent. What that comes down to is the matching speakers and as I suggested earlier, the difference between apparent and actual power. For all its presence and solidity, you’ll hear this amp at its best when partnered with the less complex loads generally delivered by two-way speakers. It’s not a question of efficiency so much as load characteristics – which is where three-way designs can start to cause concern. Paired with speakers as diverse as the diminutive Spendor D1 and the floor-standing Living Voice OBX RW3, the Classic 62 shone, leavening the infectious musical enthusiasm that marks out its parent topology with a subtlety and grace that made musical phrasing and rhythmic complexities effortlessly explicit, vocal communication intimate and expressive. The combination with the lucid precision and articulation of the D1 was especially impressive, with smaller scale acoustic music, be it Janis Ian or the Janacek String Quartet No. 2, Miles or Mozart, having a beguiling and involving quality that made for long and leisurely listening sessions (perhaps in this context it should be noted that the 62SE is factory set for 4 or 8 Ohm loads, but can be special ordered for 16 Ohm loads – ideal for all you LS3/5a users out there). But, where you can trip up the 62SE is if you step outside its power delivery comfort zone. Asked to drive the larger, three-way Spendor D9, it lost that breezy, confident quality, starting instead to sound small, clumsy, and muddled. Which is where the 120SE comes in – and where things start to get really interesting.
