I really enjoyed the mellow sound created by the USB-input Benchmark DAC 1 and the Studio Electric T3 loudspeakers. The speaker, with its 87dB sensitivity and 4 ohm impedance, is distinguished by the 6.5" broad-band drive-unit, encased in a stainless-steel sphere, that handles frequencies from 50Hz to 4kHz. Although you can see the diminutive silk-dome tweeter in the photo, the side-firing 8" woofer, which handles the single octave from 25–50Hz, is missing from view. Very, very nice.
