Dan D'Agostino Relentless Preamplifier Digital Streaming Module (DSM)
The Relentless Preamplifier is the first D’Agostino preamplifier to offer an optional DSM. This digital enhancement adds connectivity for legacy sources, USB functionality, and premier streaming capability. Field upgradeable, the DSM adds SPDIF coaxial, Optical, USB-A, and RJ-45 and Wi-Fi network inputs. For latency free playback of high-resolution network content, 10/100/1000 Gigabit Ethernet is supported.
Customized apps for iOS devices provide easy control of music collections, streaming content, and unit control. Subscription streaming services Tidal, Qobuz, and Spotify are native within the app. With appropriately encoded music files, MQA decoding is standard. Additionally, Roon Music management is also available as an alternative music management program.
Completely isolated from the analogue circuitry, the DSM is housed in the power supply/control chassis. Requiring three separate circuit boards the core element is a pair of DACs configured in differential mode with each one configured to handle the positive and negative signals for each channel. Capable of handling today’s highest resolution sources, PCM signals up to 32 bit/384 KHz and DSD signals up to DSD256 (11.2MHz) are decoded natively. Often overlooked or downplayed, the analogue section of a DAC significantly impacts the final sonic performance of digital music. Internal balanced connections carry the final analogue signal to the connecting feet and onward to each audio chassis. From here, the analogue music signal takes advantage of the entire power and analogue circuitry within the three chassis of the Relentless Preamplifier.
