M6x DAC

New DAC architecture in Dual Differential Mode, Super Silent Power Transformer and Roon Tested.
Made in the EU!

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 unbelievably 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 challenges. 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.

Mechanically Sound

Paying close attention to every aspect of the M6x DAC, we get incredible technical parameters and effortless sound quality full of grace and transparency. The mechanical construction is uncompromisingly rigid and solid in typical Musical Fidelity tradition. Front panel and side panels are milled from extruded aluminum profiles. The exterior doesn’t only look clean, stunning and indestructible, it also protects the internals against outer electromagnetic fields, and in the same way, the rest of your HiFi gear against electromagnetic fields generated by the M6x DAC. Not using a big display on the front panel only increases this effect, as the cut out needed for it would drastically complicate things.

Musical Fidelity for the Sake of Music

Therefore, musical purists who are simply looking to feel that hypnotic sensation of communication between listener and artist: they will find it here. Besides maximizing sound performance, the deliberate decision against a big display with flashing colors allows you to experience the music and only the music. Unpack the M6x DAC, carefully cable it up, just leave it at its standard settings and feel the immediate musical integration: the whole sound is sweet and clear; the treble is completely grain free and extended. The bottom end sounds endless with tactile bass dynamics. As you get reintroduced to your music library, you might, at some point, want to discover what else is possible and hear it from different stages. It is then, when the customizability and settings turn the M6x DAC into a powerful tool for experts, which elevates it into a league of its own. Explore the sound stage with upsampling or without, and see if you are drawn in deeper. Choose between 7 different digital filters and a complete oversampling bypass, disabling those filters. Full MQA decoding is performed on the M6x DAC hardware. The USB Class 2.0 input takes PCM sample rates up to 768 kHz and 32 bit. DSD support goes up to DSD256 via DoP and native DSD512. The S/PDIF inputs accept stereo PCM sample rates up to 192 kHz / 24 bit and include full MQA support!

Fun for a few minutes but beware!
Color: Blue&Purple&Orange, Color: Blue&Purple&Orange
I have 3 dogs so looking for multipacks of the same style toy is great so there is less squabbling between who gets what toy. I have a border collie puppy, a 4 yr old Irish wolfhound cross and a 17 yr old border collie. These toys were loved by each one of my dogs. The toys are floppy and easy to squeak in the octopus head. So much so that my elderly boy could happily play and make it squeak. He even collected the toys up and took them to his bed! My puppy ran off bounding through the house squeaking the octopus' head with the tentacle-legs flying everywhere as she ran around, so the entertainment value is pretty high! My Irish wolfhound loved the crinkling on the tentacles of the octopus and went straight for tearing into the orange toy pulling out the plastic, then pulling out the squeaker. The toy did ok with a game of tuggy (tug-o-war) with him and this toy would have been a great reward during a training session. The fabric is not very tough so this is not a toy for aggressive chewers. Legs were easily chewed off and unfortunately were ingested by one of my dogs which caused them to vomit repeatedly throughout the night. Same with the squeaker, they are thin, soft plastic. So if your dog is a voracious chewer, give these a miss. What I liked about these toys: 1. They were reasonably priced for 3 toys 2. These are not small toys! They are great for medium and large dogs. 3. Very fun for the dogs to play with. 4. No stuffing to clean up What I didn't like: 1. Toys are not durable for tough tuggers. 2. The toys are not reinforced for chewing. 3. Squeaker not strong enough. The toys just didn't last. There was maybe 15 minutes of play time at most before the chewing and destruction of the toys really got started. I might buy these again if I can give my puppy better supervision for her chewing these and trying to stop her from ingesting the pieces she is chewing off put I probably won't buy them again. There's too much plastic that can be eaten with the crinkly plastic in the legs.

Easily torn apart but still fun
Color: Orange+Green
This is not the toy for your dog is they like to rip them apart. That being, my sister’s dog loved these as his gift. He did tear them apart pretty easily but he enjoyed every moment of it and they were his comfort toy for at least 3 months. The colors are great, the size is perfect for tug-o-war and tossing around. The squeaking noise is loud and grab the dog’s attention easily. My sister’s dog is a corgi mix so he went ham on playing with these.

Will buy again!!!
Color: Blue+Purple
I bought a set of these toys for my 30 lb black labs (mixed breed). They are normally very aggressive chewers, and as a result, these dogs are difficult to find toys for. They destroy pretty much everything except for those very strong rubber toys which are not as much fun for them to play with. So far, these toys have lasted us 2 days and counting which is quite an accomplishment considering their soft toys typically last about 10 min. or so before they start eating the stuffing and pull the squeakers out. Between the plastic noises from the tenticles and the squeakers my dogs have just been having the time of their lives. We have to confiscate them at bedtime so we can sleep! Even though I'm positive these toys will not hold up for much longer because of their chewing habits, it was worth the money to splurge on something fun for them to get so excited to play with. I intend to replace them occasionally as long as we continue getting at least a couple days of use out of them. If your dogs are less aggressive chewers then you should definitely give this toy a try!

Great toy
Color: Orange+Green
My dogs loved getting these for Christmas! They each have one so they don’t fight over the one toy. Value for the money is good. They constantly play with them and the portability is great too. My one dog, Poppy, drags the orange one outside all of the time
