Notes start and stop crisply, and instruments are clearly placed in the soundstage. Headphone and subwoofer users will need to add additional components to the signal chain. With a smooth top end, its speed and openness can be truly enthralling. The front panel has a display that shows input selected and volume levels.
Unless driven into clipping, I could not identify any additive colorations that I could attribute to the DDA-100. In contrast to that cluttered rear is the rather stark-looking front.
Particularly well suited for smaller floorstanders and compact speakers of medium-to-high sensitivity. Plus its build-quality is solid. Clear, precise vocals stand forward in the mix, and this unit leans a touch to the mid and upper registers, favouring them over low bass. Optoma HD50 review. Hats off to PS Audio for producing a latter-day receiver that any music lover or audiophile would surely enjoy—and that is small enough to tote in a handbag.
There is minor veiling on top and just a little speed-bumping of transients and deeper bass pulses. Rather, its PWM power amplifier stage is modulated directly by the incoming signal, and the digital-to-analog conversion takes place at the speaker outputs.
Using the DAC-100 also supplied me with a line-level subwoofer feed if I needed one. At 50W into 8 ohms and 90W into 4 ohms, the Arcam also has plenty of power to rock out with most dynamic speakers.
It has both analog and digital inputs, including Bluetooth to connect your smart phone. Includes a full-function remote and headphone jack.
Soundstaging, however, is very good. It can play 176.
The treble can lean towards brightness, so you should take care with partnering speakers to prevent this from entering into the realms of stridency — the Concept 20s are good partners in that respect.
The Sprout also serves as an analog preamp with built-in, passive eq, moving-magnet phonostage, and as a low-output-impedance headphone amplifier. The remote control lets you access some of the less frequently used adjustments, including tone controls.
The DDA-100 was my first encounter with a PWM amplifier, and I was impressed by its lack of coloration and the absence of electronic noise. That care having been taken, there is no denying the precision of the NuForce. For Neat, well-built unit Good number of inputs Clean, clear midrange. Locational cues were simply easier to decipher, as was all sonic information.
What Hi-Fi? The bottom line was that for me, with current sources, the DDA-100 was sufficiently transparent and uncolored to be used as a reference device as long as it was mated with sufficiently sensitive and unproblematic transducers.
