PCM format files up to 24-bit/192kHz are converted via a galvanically isolated XMOS USB input module with incredibly accurate ultralow-noise Femto clocking, and an independent power supply powers the digital circuitry completely isolating it from the analog circuitry. Two Belleson SPX ultralow-noise ultrahigh-dynamic regulators are used to isolate the USB input from the USB output and from all other power supplies eliminating the need for USB bus power or any external USB reclocking or regeneration devices.

A summary of this loudspeaker’s qualities cannot do justice to the actual listening experience. While it is not the loudest in its class, nor does it have the deepest bass, it might just be the most beautifully made and finished speaker I’ve encountered. But the Accordo Goldberg manages to transcend the build technology and the machinery within to build a closer relationship with your ear. It plays with a superbly natural timbre, especially violin, piano, and voice, while defining wide, deep, and well-focused sound images that almost breathe with life. With the Goldbergs, you can readily distinguish wholly analog sources from digital.

But that is as nothing compared with their supremely tactile microdynamic and seductive quality, which draws the listener into the musical performance. On its own terms and at a modest scale, there is more satisfaction to be derived here than with many a larger, far more costly technical powerhouse. Highly Recommended.

iFi also replaced the external wireless antenna with an internal one, which resulted in a plastic area for BT signals. This change somewhat detracts from the original streamlined design. The build quality is excellent. The volume knob feels sturdy and is made from aluminium. The chassis gives a solid and durable impression, as do the inputs and outputs.
