The Cascade Link is bidirectional with 512x clock and link monitoring data (link error states and setup data) on the feedback channel. SFP+ phy. (must meet data rate requirements, no direct attach copper support) Synchronous with auto frame slip compensation (allows any cable latency) scrambled...
I’m fairly confident few customers would appreciate coolant lines running through their system in addition to the electrical cables :-) In the end all our equipment is convectively cooled, but these days I never design for convective cooling within the case. Vented cases allow ingress of all...
For those that are curious as to the origin of the Cascade DACs design here is an overview its origins.
Eleven years ago, when I was designing the Select DACs electronics (the seventh DAC of my design that made it to production after the MSB Platinum DAC, Link DAC 3, credit card DAC (a...
I welcome constructive criticism, but I don’t believe your comments are constructive, are actual criticism or even have any place in this discussion at all, here is my reasoning as to why.
I will be using cars in an analogy because many (most?) people have experience with them.
Your posts...
We have recently upgraded the Select and Reference to the absolute maximum performance of their physical design via software, output modules, input modules (culminating with the Pro ISL), clocks and the Digital Director. Further performance required a change in physical form, the complete...
Here is a project we have been relentlessly refining for a while now. I'm excited to release this next-generation DAC architecture. The results are absolutely spectacular.

Here is a short video as well:
I am completely biased, because I designed it, but you are perfectly describing the MSB s202. I think you should arrange a demo so you can hear it yourself.
We suggest adjusting the gain not because it changes the sound of our DACs, it doesn't, its because the input circuits on many (most) preamps (and amps) have excessive distortion at higher input levels that can be significantly reduced by lowering the input voltage of the preamp... When I listen...
Industries, companies, technologies and manufacturing is always changing and what connector is “best” today could change tomorrow. Also, what connector is “best” in one use might not be “best” in another. I would like to give an explanation of connector attributes that anyone can use to evaluate...
My vote for the XLRs with the best performance goes to modern Neutrik Gold plated connectors like NC3FXX-B. They have a unique spiral multi-finger female contact design that is super reliable and stable electrically even with repeated cable manipulation and the gold plating ensures the contacts...
My audio Precision has silver plated XLRs on it and I need to clean the contacts about once a month or it significantly affects my measurements (causes measurement failures). If I'm being lazy I can just exercise the connectors a few times and it usually fixes the problem. I also have some...
Certain distortions at that level are plainly audible, others are completely inaudible, depends on the distortions. An example of a completely inaudible distortion at that level is added Gaussian Noise. An example of audible distortion is at that level is un-dithered truncation of the data.
MQA was never about "improving" audio, it was always about distributing audio. This is currently solved in much superior ways, so MQA no longer has a valid position to fill in the technology marketplace...
Mq"B-1" is not at all what people think it is, on either side of the debate, or even what "experts" or "insiders" think it is (or was or whatever!).
It does have buried in it somewhere a clever, non patent-able, "observation", about digital audio that had the potential to
increase the perceived...
I once did a company wide survey of hearing with the goal to develop a volume control algorithm that took loundness and frequency into account. The participants sat in front of a calibrated speaker and matched the volumes of pilot tones to probe tone with a handheld contoller. Two of the...
Yes the last ADC (MSB Studio ADC) I designed was Delta Sigma, but definitely not DSD by any stretch. It used 4 seventh order differential delta sigma modulators per channel @ 6 bits 6.144Mhz per modulator with correlated digitally generrated analog dither added to the ADC references to linearize...
All computer based digital filtering I have evaluated, PGGB, HQ Player, Roon, and many more…, is highly colored and imprecise in all settings and configurations, If you ”must!” have the color and grain they add then by all means you can use them, otherwise stick to unfiltered and unprocessed...
It’s not vague. “Pass through” means the digital director passes through the data unchanged. The DAC works normally with the benefit of the superior isolation of the Digital Director. “Filter” means the Digital Director offloads all the digital filtering the DAC would have done in its onboard...
I really don't like it when "conventional wisdom" becomes an "immutable physical limit" so I would like to clear some things up.
First, a power supply is simply a stiff buffer amplifier fed with a reference signal. While it is not simple or cheap, making a reference that is sub 1uV in the audio...
All current MSB DACs (Discrete, Premier, Reference and Select) can actively use the off-board digital processing in the Digital Director. It is selectable via an updated DAC menu option and is signified with a (+) on the DACs display. The DAC firmware that allows this functionality did ship...
Mixing any signal from stereo to mono without advanced digital algoritms to do so is a bad idea. Depending on original recording you can get huge frequency nulls in the mixed output. So either generate a separate sub channel with software or use just one output (Left or Right your choice) for...
If you want the best, get some of the caps with newer high temperature, high stability, long life, low ESR electrolytes such as:
Nippon Chemi-Con (aka United Chemi-Con)
LXS
TXH
KEMET
ALF80
ALC80
Rubycon
VXG
VXH
Of course you should specify a minimum of the original capacitors voltage rating...
A slightly more nuanced take on this truth is that while 24bit/88.2khz or 24bit/96khz is definitely sufficient for maximum quality as a storage or transmission format, increased sample rates or precision might be necessary for other reasons. If you are mixing or processing, a higher word...
Conversion to fiber uses more power, but done with the correct data pattern generates less noise than copper cable drivers (because the cable drivers must deal with the reflections of imperfect cables). Copper carries a large amount of conducted noise (not generated by the driver itself, but by...
Right now some input data such as the data from S/PDIF inputs come into the DAC not synchronous to the DACs clock. They are buffered in the onboard memory in the DAC and then played back from local storage. The Digital Director takes over this task and sends all data to the DAC synchronously...
The Digital Director is designed to maximize the conversion potential of any current MSB DAC. It does this in three ways, by providing perfect digital isolation, offloading processing from the DAC itself, and re-clocking all incoming data regardless of the input format. It supports all of our...
