M6x DAC – Overview
Our M6x DAC is a new milestone in the history of Musical Fidelity DACs. Its predecessor, the M6s DAC was one of the first to use the critically acclaimed ESS 32-bit HyperStream II DAC architecture. With the M6sR DAC, we continued to improve the firmware and added a few other quality of life improvements. DSD was now easier to use, we had full Roon Support and in- & outputs were updated to keep up with the fast moving digital audio landscape. And the other big thing: the M6sR DAC was now being made in the EU!
Technical Talk
With the M6x DAC we went even further. Building on our knowledge and experience with Sabre ESS chips, we upgraded them to the newer ES9038Q2M, and now use two of them in dual differential mode for a pristine dual mono design. The inclusion of a Time Domain Jitter Eliminator results in superb SNR and THD+N performance with unbelievablely detailed transient response. Other advances in the DAC section include upsampling and re-clocking. Upsampling can independently be switched on or off. The 16-core XMOS and CPLD MAX II Altera processors ensure there is always enough headroom for these operations, the new digital filters and the MQA processing. The single ended RCA and balanced XLR outputs each have their own output buffer. Via the XLR plugs you can enjoy a fully-differential amplifier design enabling a fully balanced output. Both output stages deliver superior audio quality, exhibit very low noise, large output voltage swing and high current drive. The excellent gain bandwidth and very fast slew rate produce exceptionally low distortion.
Super Silent Power Transformers
The M6x DAC displays our continued development of our Super Silent Power Transformers. Industrial grade power sockets with EMI filter and DC blocker stop interferences and eliminate transformer hum. The encapsulated toroidal transformer with low core saturation is ideal for audio applications and especially perfect for digital audio due to its extremely low electromagnetic radiation.
Correct PCB Design & Layout
Digital to analogue converters, compared to analogue amplifiers, present their own design challanges. They work in different domains, have their own requirements and need to be treated as such. Power requirements are unique and solutions designed for amplifiers will not show similar results when paired with digital circuitry. We have always held circuit board design and layout up to the highest of standards at Musical Fidelity. We are not believers of flashy board design just for the sake of looks. The design & layout need to be custom-tailored to each application, measure well AND sound as envisioned. Only then have we done our job. At this point, we have given the listener a palpable sense of the recording venue that places the performers in a real-time holographic space in their own homes.
Headphone Amplifier
The built-in headphone amplifier‘s current-feedback AB architecture delivers high bandwidth, extremely low noise, and up to 128dB of dynamic range. Three key features make current-feedback amplifiers outstanding for audio. The high slew rate prevents odd order distortion anomalies. Current-on-demand at the output enables the amplifier to respond quickly and linearly; when large amounts of output power are suddenly needed, the amplifier can respond extremely quickly without raising the noise floor of the system and degrading the signal-to-noise ratio. Gain-independent frequency response allows the full bandwidth of the amplifier to be used over a wide range of volume settings.
EISA-voittaja 2022-2023
EISA-raati toteaa;
” Da-muuntimien todellisen pioneerin, Musical Fidelityn M6x DAC on arvoisensa seuraaja Digilog-mallille, josta kaikki sai alkunsa – vuonna 1988. Laitteen vaatimattoman mutta hienosti muotoillun alumiinirungon sisukset vakuuttavat, mukaan lukien mittatilaustyönä tehty kelloratkaisu ja ESS:n viimeisimmän kehitysasteen da-muunninsirut, jotka toimivat kaksoismonona ja tukevat korkearesoluutiomateriaalia aina 768 kilohertsin ja 32 bitin sekä dsd512:n tasoon saakka. Tositoimissa M6x DAC tarjoaa hämmästyttävän toiston ja äänikuvan kaikkine yksityiskohtineen, ja käytettävissä on kahdeksan suodatinta, jotka hienosäätävät laitteen äänen juuri sinun makusi mukaiseksi. Tulot, mukaan lukien usb-b ja aes/ebu, kattavat lähes kaikki digitaaliset lähteet. Eikä M6x DAC ole vain erinomainen lisä kaiutinpohjaiseen erillisjärjestelmään, sillä siinä on myös mainio kuulokevahvistin sisäänrakennettuna! “
