Fantastic supplier
Fantastic support from Sales department; fast and easy shipping; product arrived as per advertised. Regarding SP4000 performance, first few hours show a big leap from SP3000, well worthy the investment, IMO - we are now really talking about TOP audiophile sound quality, amazing detail and liveliness, great soundstage (real and proportional), and the Dar engine really improved against the SP3000'. Bravo A&K 👏🏼
