Dress code: sharp. In the D2's price class, it's common to see thick or thin face plates bolt to paneled chassis, perhaps even mate to folded sheet-metal covers. Yet the D2 goes beyond even cut extrusions because each one-piece block needs individual retainer lipping milled in to seat the inset front and back panels. It's a rather costlier solution to avoid visible fasteners and here machine or anodizing shop rejects become not individual panels but the entire case. Ouch! Here we see front panel and corpus...

... here the layered mother board, still plastic remote and replacement no-volume buffer module. Following our minimalist cos, even the wand with textured belly eliminates redundancies such as company name (if you bought it, you surely know) or up/down lettering for source and volume when the layout and markings are perfectly adequate to the classy task.

The obvious secret to the D2's compact dimensions is the potted switching power supply preceded here by not one but two inline AC power filters whose precise makeup and size purportedly underwent numerous CC-prompted iterations to lock in final performance.

As with the D1, the flying leads to the dual-mono BurrBrown DAC chips are protected by bubbly glue and now this plexi roof as a visual 'don't touch' reminder if the user-switchable modules are replaced.

The combined volume control/buffer board eschews singular attenuator chips to instead execute fully balanced volume with quads of resistor-ladder IC per half cycle.

Here is the main processor board for the company's proprietary digital filter, buffer and display/control functions.

With the precedents of D1 and H1, the D2 clearly continues the established design and build ethos to feel near Scandinavian in the timelessness of its simple exterior; thoroughly SMD/SMPS modern under the covers; and thoughtful with features like buffer defeat, USB 1.0/2.0 select and 0.25dB attenuation steps. Would sonics follow the elegant Armani suit?
