Reviews "it sounds purposeful and powerful, displaying the ‘grunt’ expected of a flagship while bringing grip and depth to percussion and basslines. This solidity continues all through the audioband, for a listening experience possessing plenty of body and heft" "the amp’s handling of the piano samples, and that driving rhythm, elevated the track to almost hypnotic status" read the review in HiFi News video review - please allow 10 secs to load Specifications Is a Streamer and Amplifier : ✅ Yes DAC: ESS ES9027SPro Bit Rate Capability: 32 bit/384 kHz, DSD512 Supported Digital input sample rates: Up to 192 kHz Analog Input 3 x (RCA pairs), 1 x XLR (balanced pair) ✅ Yes Phono Input MM & MC ✅ Yes Digital inputs: HDMI eArc (1), Coax (2), Toslink (2), USB-A for PC HDMI ARC Input: ✅ Yes Bluetooth HD 5.4 aptX input, and output to Bluetooth headphones ✅ Yes Headphone out. ✅ Yes Variable Audio Pre Out:1 x (RCA pair), 1 x XLR (balanced pair) ✅ Yes Subwoofer Out: ✅ Yes, dual Dirac Live Room Correction ✅ Yes Roon Ready: ✅ Yes, with software update High-resolution display for clealy visible album artwork and metadata ✅ Yes Supports Apple Airplay, Google Cast, Spotify Connect and Tidal Connect ✅ Yes Setup with ARCAM Radia App for presets, Internet Radio and Podcasts ✅ Yes Continuous power output (0.5% THD), per channel2 channels driven, 20Hz—20kHz, 8Ω: 180W2 channels driven, 1kHz, 4Ω: 300WHarmonic distortion, 80% power, 8Ω at 1kHz: 0.002% Analogue InputsNumber of inputs: 3x RCA pairs + 1 XLR pairPhono Inputs: MM and MCFrequency response: 20Hz—20kHz ± 0.2dBSignal/noise ratio (A-wtd, ref. 50W, 1V input): 106dB Digital InputsSupported Streaming media: FLAC, WAV (LPCM), AAC, ALAC, AIFF, DSD (up to 256), MP3, MP4, OGG, WMASupported Streaming Bit depth: 16, 24, 32Supported Streaming sample rates (kHz): Up to 384 kHzGapless Playback: YesDigital Audio Inputs: 1x HDMI eARC, 2x Coaxial (RCA), 2x Optical (Toslink)Supported Digital input Bit depth: 16, 24Supported Digital input sample rates (kHz): Up to 192 kHzFrequency response (filter 1): 20Hz—20kHz ± 0.2dBSignal/noise ratio (A-wtd, ref. 50W, 0dBFS): 110dB Wireless SpecificationsBluetooth Profile 5.4; A2DP Sink/Source, AVRCP, BLE, Snapdragon Sound, AAC, LE Audio, AuracastBluetooth Transmitter Frequency and Power:2,402 MHz to 2,480 MHz
