Adagio by metrum acoustics™ (digital analog converter)

DAC / PREAMPLIFIER DESCRIPTION What more can you do after launching one of the best dac’s available today? We are aware that our current flagship Pavane is hard to beat but at least one idea was not realized yet. The idea of having a decent volume control to prevent a necessary pre-amplifier could improve performance dramatically. However, we also know that the way of introducing such device in the signal chain can also have a negative effect. Experiments were made and as result the best sound was coming directly from our Transient™ modules. Even the digital approach did not convince us but still one idea was not tried yet. Especially in case of R2R ladder dac’s it is quite easy to change the output voltage of the dac by changing its reference voltage but to realize this, dedicated dac boards were designed to get the best regulation possible. Like our Pavane, “forward correction” techniques are used to drive both mono dac boards. The result of this process is an extremely high linearity, right down to -140 dB, which gives the Adagio a realistic 24 bit dynamic range. The Adagio is a step forwards as it omits a pre-amplifier. It is musical, honors the Non-oversampling principle and simultaneously incorporating the technological progress that has been made over the years. Bazı incelemelerden: “Adagio DAC, dosya sunucusundan gelen sinyali değiştirmez: örnek, aşırı örnek veya filtre içermez. Bu, oldukça tatmin edici ve tarafsız bir müzik dinleme deneyimi yaratır.” Richard Varey Witchdoctor is a online entertainment magazine. “Dönüştürücülerdeki referans voltajını düşürerek veya yükselterek hacim kontrolünün akıllıca uygulanması, daha önce hiç görmediğim bir şeydi ve kusursuz çalışıyor. Hangi ses seviyesini ayarlıyorsanız sesin kalitesinde, çözünürlüğünde veya aklınıza gelebilecek herhangi bir şekilde değişmeyecektir.” René van Es, the-ear.net, Hi-Fi Music Gear Magazine “Farkında olduğum tek diğer üst kısım katı, 24 bitlik ikili kodunun farklı bölümlerini ayrı toplamadan önce ayrı ayrı işlemek için birden fazla R2R merdiveni kullandığı ve saf ses kontrolü için referans gerilimini ayarlayan ses rüyası DAC’tır.“ Srajan Ebaen, 6moons.com DESCRIPTION ADDITIONAL INFORMATION ADDITIONAL INFORMATION Weight 10 kg Dimensions 54 × 43 × 22 cm Voltage & Color 110V Silver Line USB, 110V Black Line USB, 230V Silver Line USB, 230V Black Line USB, 110V Silver Line I2S, 110V Black Line I2S, 230V Silver Line I2S, 230V Black Line I2S Specifications 24 Bit balanced dual mono volume controlled DAC Non oversampling DAC Forward (FPGA) corrected 4 DAC'S per channel in differential mode 75 VA via 3 separated toroidal transformers 110/115V AC 220/230V AC 60/50Hz Input 1x optical, 2x coaxial 1x BNC and 1x RCA AES/EBU and USB Output 1x stereo pair single ended variable max. 2 Volts RMS Output 1x Stereo pair XLR: variable max. 4 Volt RMS Frequency Response 1Hz – 20 khz -2.5 dB. 44.1 kHz sampling Frequency Response 1Hz – 65 kHz – 3dB .192 and 384kHz (USB) Distortion 0.006 % THD Noise Floor -155 dB related to 2 Volt RMS Output impedance RCA 100 Ohm, XLR 320 Ohm Sampling rate Optical 44.1 – 96 kHz Sampling rate Coax and AES/EBU: 44.1 -192 kHz Sampling rate USB 44.1 – 384kHz Dimensions 440 x 320 x 85 mm Weight 10KG
