As the sides of the slim-line Timbre Technology TT-1 DAC are radiused rather than flat, it's elegant compared to its typical boxy competition. While the TT-1's handsome shape stands out more than your average audiophile device, its curved sides help create a stronger, less resonant shape than the usual box, and serve as just one of the many elements contributing to a high degree of mechanical integrity and damping.

Looking at the Digital Link II's build quality and circuitry, it's hard to believe that it can sell for $499 at retail. The Digital Link II shares the same appearance as PS Audio's SuperLink and UltraLink processors, but has a 4"-shorter chassis. The ¼"-thick front panel uses PS Audio's familiar touch-sensitive switches that turn the unit on and select between coaxial and optical inputs. LEDs above these switches indicate when the unit is locked to the digital source. A third LED illuminates when power is applied.
