Stefan Gawlick has posted a review of, and lab report on, the Audionet ART G3 CD player (€5490) at i-fidelity.net. His conclusions:
The ART G3 can’t either lever out one of my favourite riddles of the digital world: irrespective of careful decoupling measures one can hear the base which the player sits on. Whether the little Lack table from Ikea, a massive rack filled with sand or the lighter solution by Phonosophie: all acoustic properties are clearly noticeable and hence, after some comparisons, the ART finally sits on the top Control Board of a Phonosophie rack. Here it performs freely and openly, unfolding airy harmonics and pumping out a well-structured, massive bass. When it comes to selecting a power cord, it appears to be less demanding than its predecessor, but reveals a certain soft spot for non-shielded cables. So it is finally supplied over an HMS Gran Finale. Apart from that, the sonic difference between the balanced and unbalanced outputs has dwindled further. True, via the RCA line the ART sounds a tadbit more openly and smoothly, yet with such marginal differences one is better advised to hinge the connection choice on the quality of the preamp inputs.
