The Digital Director - A new MSB product improving everything from the source to the output

[Armsan]

I was just reading more about this product. I just realized that Digital Director adds about 260ms of latency according to one of the reviews. Chord M-Scaler uses a 1 million tap filter and adds about 660ms of latency. That means Digital Director probably use a 400,000 tap filter for upsampling before feeding the MSB DAC. Most interesting. Of course, tap length doesn't determine sound quality. The filtering algorithm also matters. I also wonder if the Digital Director does some noise shaping too.

Can you, please, share the link of where you got that information? The DD doesn’t perform upsampling of the played files. About the algorithm of the, till now, unique filter I don’t know how it works and maybe Johnathan or Daniel can enlighten us. Actually with these ears, in my system and in my room I prefer the Passtrough mode. I’m sure in the near future there will be a filter that I will love.

you are correct that the sales literature for digital director doesn’t talk about up sampling but uses the term digital filtering. But if you’re applying a digital filter that has a 260ms latency, what are you filtering and how are you filtering, you’re probably upsampling. Filtering is just the technically correct terminology.

The problem is that as far as we can tell, the DD is not changing the sample rate, and ultra-long, high-tap filters are a Chord thing and not every manufacturer or listener likes them. There are other things that could incur latency such as buffering and re-clocking and more DSP intensive filter algorithms that don't involve increasing filter taps.

Read what he is using lol. You can’t make him hear if he don’t pay attention to your comments.
I’m guessing he is a bits are bits
Enough said.

Is that a disparaging comment directed at me?

Yes but as a joke only. this hobby is funny to me
We each think we know and there is nothing wrong with that
it’s all in fun

Regarding the DD I’m sure it’s doing a lot of things
Msb is expensive but really good

Okay.

You thinking differently to me or believing that you know more about anything than me, or anyone else, certainly will not diminish my enjoyment of music at home. However, your discourse is exclusionary, whether intended or not from an engagement perspective, and that does diminish my enjoyment of this forum. So a word of advice, feel free to be self-deprecating but unless you know someone very well, keep your "jokes" to yourself.

Interesting that the author of this review found the Video Mode better sounding.
What do owners of the DD here think?

The Video Mode option, button 5 of the remote control unit, is present in MSB DACs, long before the DD, and has a very specific situation to be used per MSB recommendation. Please refer to page 12 of the Select Manual at MSB webpage, support section. Maybe this reviewer likes jitter.

Perhaps. But you can see video mode and non-video mode filters are just different based on those review measurements. there is more “ringing“ in non-video mode and there is more rejection of higher frequency sound in non-video mode. So it’s not just about jitter. To me, it comes down to audibility of digital filters (not just jitter) and what filters people prefer (even if mathematically some filters reconstruct the original analog waveforms more accurately). I think there are so many biases around the buzz words upsampling or NOS filters or tap length or ringing out there that MSB is purposefully avoiding these terminology in its marketing material to not alienate specific customers. I mean, if it sounds great to you and you can afford it, it sounds great, regardless of the buzzwords or tech behind the sound.

You may very well be correct since you can just buffer with audio latency for an arbitrarily time to reduce jitter. But MSB even back with the DAC IV had the option to do a 6000 taps 32x upsampling digital filter. And since most DACs have <100 taps for digital filtering, back then 6000 taps would be considered a long tap length filter. I’m not aware of any digital filtering that stays at 44.1kHz that can increase >22kHz rejection without upsampling but I‘m just a hobbyist with no engineering knowledge so I probably don’t know what I don’t know.

Way back when. I had the 5 with all the bells whistles
heard the sel 1 was not better or NIR for me
when sel 2 came out heard this too a few times better but still insane cost for sound
next the long awaited release of there new filter
Honestly best res book I heard back then period
I still feel even today the Sel 2 is a master at rebook.
im not. Fan of upsampling over all while it makes some parts better it also has its own warts
The sel 2 and even the 5 I had was very good upsamping to my ears.

I think you’ll find a switched power supply in the Premier and a linear power supply in the Ref.
in terms of your decision I had the Reference working with the Innuos Statement before adding the Ref DD. Excellent results. MSB does raise the performance level when moving from the Premier to the Reference. .
Even with the Ref DD, I don’t believe I’ve reached Select levels of performance. Perhaps the same would apply to your Premier DD vs Ref decision. I believe your best choice long term would be the Reference. Who knows, a Ref DD could be added in the future. That combo is simply sublime! And you’ll be very pleased with the Reference, stand-alone, IMHO.
good luck l.

Thanks for sharing, we have very similar setups. What input method were you using from the statement to the Reference prior to adding the Ref DD? What type of sonic improvements did Ref DD add?
