I've auditioned Borresen Z1 Cryo with Aavik S-280 + D-280 + I-280 with assorted Ansuz cables.
It was perhaps the best bookshelf setup I've heard so far. Huge and organic sound.
Recently I've heard a pair of Berlina RC3 driven by Perreaux 300ix with Synergistic Research cabling. Surprisingly, this setup sounded identical to the Aavik+Borresen+Ansuz. Aavik DAC is R2R according to the dealer, but the ES9038PRO Sabre DAC in the Perreaux sounded very musical and organic also.
All in one boxes are getting really good nowadays.
