Dutch & Dutch 8c: pre-Roon Ready thread

[Craig_Palmer]

@dabassgoesboomboom

How can Dutch and Dutch know the distances from my listening position and walls and ceiling and spacing and other acoustic properties of my room? And everyone’s room?

Was trying to help answer this one and provide a bit more detail on how the process worked in the 8Cs.

Thanks for this.

I can’t recall if adding room boundary distances was always there (like when I demo’ed them very early on) or a later firmware/software addition. Very very useful indeed.

But I still think ‘best’ is measuring at your listening position/s in your room… including step response. Even if it ends up being just a verification… worthwhile doing.

[Craig_Palmer]

Back wall, side wall distance inputs to the 8Cs was always there. It must have this data, at minimum, to properly fire the back woofer that’s bonding with your walls and likely is being used to align all the driver outputs. You can’t replace this correction/adjustment with Audiolense because you don’t have control of the individual drivers in each speaker. Of course you can further correct on top of it to adjust speaker left vs right timing and/or room issues.

This part I either forgot or wasn’t aware. I demo’ed these very early on.

Thanks for the info.

Of course. Right now each driver I have not only has it’s own DAC and amp but each is also time aligned perfectly, using measurements at listening position… not using a handful of distances and estimates but using measurements in the room… this is something not possible with 8C’s

I’m joking around here a bit. We don’t need to go in an infinite loop.

[J.D]

Yes . But the EQ does a lot . Roon might be a bit more complex in the beginning
I used convolution filters in ROON .

Is anyone on this thread using a turntable with their D&Ds? I’ve been thinking about adding one and I’d be curious about people’s experience.

[Nathan_Donaldson]

I have my LP12 setup with my D&Ds.

Currently it goes LP12 > Phono stage > MiniDSP SHD > 8c

I also have a lumin connected to the SHD

It works well enough, but the level of the turntable is a lot lower than the Lumin. Also I use rooDial to control the Roon volume but have to use the miniDSP to control the turntable volume. Its all a bit of a pain.

But my understanding is, that once the D&Ds are Roon Certified I can have my phono stage connected directly to the D&Ds. That when Roon isn’t playing it will switch automatically to the analog input. I understand that I may also be able to use the rooDial to control the volume on the speakers even while it is playing analog (hope I have understood this correctly :-).

Currently my phono stage has RCA outputs which are at a lower level than XLR. My plan is to change phonostage so that I can get XLR output - this will be useful as I will be driving much longer cables (to the D&Ds rather than to the SHD)

[Aaron_Garrett]

Thanks this is very helpful since I too have a miniDSP and was thinking of getting a Linn! I noticed the Linn phono stage has XLR outs. I’ll wait since who knows how long the Roon certification will take.

That’s correct.

The linn radikal has both outputs, rca and xlr.

When i had the amazing DD8C´s the Streaming input overruled the analog and digital XLR inputs.

So you are right there. I actually tried my DD8C´s together with a turntable. Turntable → riaa → DD8C analog XLR. I streamed ROON directly from my ROON Core and was controlling the volume, I could even starts the 8C´s directly from ROON. When no music was played on ROON , the DD8Cs switched to the analog input after 5-10 seconds.

Maybe I am wrong now, it was a while ago I had the 8C and there might be some new features, but I don’t think you can use the rooDial for the analog input. It controls ROON volume , and the 8C then needs to be switched to the Ethernet/streaming input for you to be able to control the volume.

Maybe Dutch and Dutch will release some kind of remote in the future. That would be pretty awesome actually.

Huh?? Did you have Roon integration?

[GraemeM (Graeme)]

Has anyone else noticed a loud cracking noise coming from their speakers as they expand in heat (sun for example). One crack every few minutes until warmed.

[Didier]

Yes, I have the same cracking noise with my D&D. I think that the wood is moving with the heat.

He was a beta tester for the Roon integration. See an earlier post from him.

Dutch & Dutch 8c: pre-Roon Ready thread

In my ears , the best sounding input is: Ethernet Digital AES/EBU Analog XLR Even though i could only try the ethernet (ROON) input for a couple of hours, i heard the difference right away. There is one track Artificial Algorithm by Slow Meadow . At 2 minutes 15 seconds - 2 minutes and 23 seconds there is some low bass echo , dont know how to explain it. With analog XLR input this bass echo has very little texture and layers, with ethernet (ROON) this bass echo becomes more tranperent. More t…

[J.D]

Correct

I was one of the beta testers.

It actually does when Roon is not playing music. Then the rooDail controls the input volume through Roon.

[Nathan_Donaldson]

That is so awesome! The rooDial is such a great remote!

Maybe it’s just the two of us. I wonder if it’s a warranty issue? I’ve never had a speaker that makes cracking sounds before. It’s a bit annoying.

[killdozer (Brutalise me with music)]

Sorry to butt in, am not a D&D owner but I’m interested enough to keep reading this thread. I’d get this looked at as it doesn’t sound good to me. It’s sounds as though they have 2 materials bound with significantly different thermal properties (think bi-metallic strip). If it’s repeated it’s the kind of thing that shifts veneer and breaks joints apart. Understandably easy to miss in product testing, it’s a real “living with” issue. Might be nothing but I’d not wait to find out.

It’s probably not just the two of you, but it will depend on the temp variation where the speakers are located.
