Setup advice for a high end system

Hi Eric,

When you have roon processes distributed over 20 physical cores, you can get great sonic results

Well… This is embarrasing…Big oopsie… SO… Ummm… hahahahaha… I was doing my Angel AB Melco / lightweight player VS roon + Taiko compairson kinda ummm… wrong… I had roon playing the Qobuz version and the Melco playing off the file… hahahahaha… OOPS… So my HUGE issues were really local files VS Qobuz… hahahaha… Operator error… I blame the GUI ! hehehehe, I swear it was not the operator !!

SO… Getting this RIGHT now… Its VERY close. Its now in the realm of burn-in for the Taiko Mundorf caps. Maybe switch burn-in. There is still a difference, but, its clearly in the right league…

Upon advice from CH, I turned off the MQA. The reasoning was complex, but, this did really improve Qobuz. With my hardware MQA = off…

So… Sorry for my false red alert… Oopsie… hehehehe… I will do a bunch of burn-in and report back after everything is settled in… I have not tried USB yet, but I intend to.

OH… I did settle on a network topology that worked best for me.

Taiko optical > SoTM Switch with ext clock to CH T1 > Optical > SoTM switch ext clock > CH C1d DAC Ethernet > optical to outside world. This opto isolates the server, the DAC and the outside world…


Happens to the best of us, especially to luddites like myself! :grin: I’ve done that myself–my audio system, even working on a car. Look over everything, digging so deep into every single part, only to find the simplest (dare I say “dumbest”?) error that was staring me in the face the entire time.

I’ve generally had excellent results with Qobuz, virtually identical to CDs or local hi-res files…but only if it’s the same mastering. Sounds like you hit a bum version of your album on Qobuz. But, no matter–you’ve found the issue!

Glad you got things working to your satisfaction!
It is something of a rite of passage on this site to post ‘stupid’ things we’ve done. So don’t go thinking your are somehow special. :wink:

Good to hear Chris,

Now what you need to try and report back is the following

Copy the file from the Melco on to the PCIe storage on the Extreme

Choose carefully from roon and compare the SQ of the file coming from the Melco and coming off built in storage

Already did that. The Taiko is burning in. Next week I will do a proper AB. Im also burning in 2 SoTM switches. Im also going to get a reasonable USB cable to listen to that.

Glad Chris found the probable point of departure, but it does sort of beg the question.

Why should streaming sound worse than local storage, given equivalent resolution files and same Master ?

I can’t hear a difference on my system, but I don’t have good SQ discrimination or a system as resolving as this one.

Well… I just assumed there was compression or something extra going on. Honestly I have not looked to closely to these streaming services to know what they are doing with the stream. I just assumed its was not the same starting file, or, some compression had occured ?

Im not quiet sure what turning off MQA did, but, things are better. I have not looked fully into what turning that off did… Maybe it works best with Meridian gear ? Not so much with CH hehehehe…

But yes, big obvious difference… I guess im just old, but, I consider these sptreaming services kinda like radio. Radio can’t possible be as good as my 1/2" 2 track open reel tape on a Studer. So to my mind streaming can’t be as good as local files. It would be good if it could tho.

It’s all in the mind.

Which lightweight players are you referring to, Chris?

In my case UPnP. and the CH precision app…

Indeed music is a ethereal experience for sure that is possibly governed by deterministic probability. Experiencing reality, alters it. Measuring, changes it… After all, what is reality anyway ?

So im thinking about a network topology… This seems about right to me…

The CH Precision gear needs to connect to networking and be PoE.

Oh nice! Thanks @Chris_Stephens

Maybe you’re dreaming this and none of us are really here posting on this forum??

We both are and arn’t.

I believe many MQA DAC products cannot switch filters on the fly for MQA/non-MQA music. So they choose to always enable MQA filter when you enable MQA, even if you’re not listening to MQA music. If you like MQA filter, then this is fine. If you don’t like the sound effect of MQA filter, then you may find that turning it off sounds better for non-MQA music. (This is not the case with Lumin products - we properly choose filters by predetermining whether a music is MQA or not.)

Hi Chris,
have a look at
First you should not expect a “normal” pc or notebook or Intel core to be “audiophil”. These items are designed to process data, but as we know in the meantime, digital data of music are sensitiv to several aspects of disturbance ( which are irrelevant in data processing ). Some of these aspects can be avoided by a special hardware layout.
Second, what audiodata offers is a correction system, which is not only able to correct problems occurring from the audio hardware but additionally can correct problems from room acoustics as well. To some extend it is more effective to invest in such a special audio server and correction system instead of even more expansive equipment.

This is a very interesting stream. I also have a high end Naim system and I cannot tell the difference between steaming from Qobuz, streaming from the NAS or playing a CD of the same file in WAV format. CD may have an edge sometimes but you have to be very attentive and focus to find out.
In one occasion I was having problems with the SQ via streaming. The CD was sounding much much better. At the end I found that I was using a shielded Ethernet cable that was creating a problem with the ground of the system. Changed the cable, problem solved.
Now to listen more music!


I’ve spent considerable time trying to find what I consider the best sound for my listening environment and have found that a signal path with the least amount of processing gives me the “cleanest” sound and allows me to hear the music as it was recorded. I let my dac do the decoding and rendering and use Roon as a bit perfect player which allows a lossless path from beginning to end. Everyone’s “ears” are different but this works the best for mine. Other than that, I have no idea what you might need to do and can only suggest you try a “lossless” path and let your "ears’ guide you. Keep smiling.

Hi! Just a few observations from someone trying to optimize sound while using roon. The best may be to completely avoid going through a switcher and go directly from a high quality storage to your dac. I found keeping my music on a dedicated audio storage (I use a Melco N1 server) helps a lot even with use of a separate roon core on a pc. But the best would be a dedicated roon nucleus with storage, or better an Innuous Core/server. Read the reviews. This would directly feed your dac, optimize for quiet storage and allow ripping all without going through a noisy switcher. I’m saving up…heard it at my stereo shop. They are great.
