An old circuit with a modern look versus a new design with retro styling as Ken Kessler hears valve amps from Papworth and Sonic Frontiers
Contrary to the practices of most specialist companies, some still believe that small is beautiful. Despite the continuing displays of excess from across the Pond, enough manufacturers realise that the only way to get quality sound into certain homes is to 'down-size'.
Looks like valves, smells like valves, uses transistors – Ken Kessler hears 100W of single-ended MOSFET power from the pen of Tim de Paravicini
Statement amps are nothing new to Tim de Paravicini, his original EAR 509s and 549s hardly being minor projects. Neither were the first amps to bear the Yoshino names, a pair of designs showing that single-ended topology could be applied to both valves and transistors. But the latter, while Tim was able to voice it to ape the tubes, ran just as hot as the valves, and proved just as inefficient as all single-ended designs are known to be, so why bother? Damned if I know, for Tim's latest is a huge mutha of a single-ended amp... and it's solid-state.
