I knew Goldmund were at the show but the signage was a bit confused and eventually I found it at the Sonata room, a dealer/agent based in North London who uniquely hold the Goldmund agency for the UK. It was worth the search because fine sounds were on demo in this room, from the Goldmund ProLogos Plus.
A three-way bass reflex design, stand mounted, it is distinguished by a cantilever styled frame support while the enclosure is firmly grounded mechanically by a rigid vertical central spar/spike. It is fully active, very powerful and wirelessly connected to music sources via a high definition proprietary Goldmund interface. It has a 3-way crossover implemented in the digital domain, with full amplitude, phase and time correction. Total amplification amounts to 1.2kW and it sounded like it, fully in control of the input signal. The price is somewhere north of £60,000 complete.
There was much more to see, which was impossible to cover but these were some highlights which attracted my attention. My apologies to those not visited.
