The WANDLA is another home run from Poland’s Ferrum Audio. Nicknamed ‘The Convertor’, this innovative DAC/preamp goes the extra mile thanks to its combination of an ESS Sabre DAC chip, custom DSP and bespoke analogue electronics. Performance is superb, with music of any genre faithfully rendered and packed with detail, while Dynamic Digital Filtering, which incorporates filters from specialist software house Signalyst, provides options to finesse the listening experience. Want to improve the WANDLA’s performance further? Just add the EISA Award-winning HYPSOS as an outboard power supply for even better sonics.
