Thank you so much for all that valuable info.

I did faced issues in the past and your feedback shows that I was right to ask questions.

Thanks Chris.

Forgot to ask - will my music be "reprocessed" by Roon - should I allocate time for this, or is copy and go?

Thank guys

This is the thing. I've had it go both ways and I don't know what caused it to work one way or the other.

Roon keeps hashes of scanned/processed content, so rescanning the same files (even in a different location) will be fast.

Is your current music on an external drive? I have upgraded HD and swapped out a backup drive with no issue. I just always use the same name for the volume of the ext drive. The Roon database and settings keeps all the information and just points to the music location.

[jacquesr]

By following your advice I have been able to complete the operation without breaking a sweat.

I think the issues some might have had in the past, including me, were with the previous version which managed music storage differently. Roon is getting more mature one version at a time....

Fairly major update to Roon again today WRT to DSD. 

 

Version 1.3, Build 216 adds DSD > DSD upsampling with no intermediate conversion to PCM, additional DSD filters (steep / slow rolloff, linear or minimum phase), and additional modulators (5th and 7th order "CLANS" - whatever that is!), as well as upsampling to DSD512 if your OS + hardware supports it.

 

I have built a fairly long DSP chain, including EQ, crossfeed, resampling all to DSD256, etc., and still seeing only about 25% utilization on my vintage MacMini Nice.

Am trying out the upsampling to dsd512 as we speak.... 

[christoph]

Have you two also compared roon upsampling to DSD with the upsampling in HQPlayer? I haven't tried with the new roon build 217 upsampling to DSD512 but before ( build 208?) I clearly preferred HQPlayer with both upsanpling to DSD256.

With the earlier builds, I preferred HQPlayer, as well.  I can say, though, with the current build, and DSD > DSD resampling, I don't hear much to distinguish the two; i.e., Roon sounds just as good as HQPlayer - to my ears, at least.

 

I would love to see someone do an actual apples:apples comparison with the appropriate test gear.

Hi John

Thank you for your assessment.

That would be quite a sensation if roon on it's own sounded as good as HQPlayer 

And that with much less computing power...

What where your settings in HQPlayer and what now in roon?

 

Cheers,

Christoph

HQPlayer - poly-sinc-shrt, AMSDM7 512+fs, DSD256

Roon - Precise / Linear Phase, 7th order (CLANS), DSD256

 

I will say that Roon chokes when you add in channel mapping 5.1 > stereo (if needed), where HQPlayer does not.  So for 5.1 to a stereo setup (e.g., my headphone rig), I must offload the channel mapping and DSD conversion to HQPlayer   Fortunately, I only have about 10 5.1 albums in my 6,500 album collection, so not too much of an imposition, and the same 5.1 albums play brilliantly on my speaker rig, where no channel mapping is needed.

 

In any case, nice to be able to mix and match as necessary / desired

From here:  https://community.roonlabs.com/t/roon-1-3-build-216-is-live/24161

 

CLANS (closed loop analysis of noise shapers)

 

I guess that makes it crystal clear. 

[austinpop]

No word on MQA SW decoding, it looks like.

Just heard feedback on the new Roon up sampling

 

 "just checked Roon upsampling to DSD512 with audiolinux.
Configuration: Audiolinux Extreme, priority Extreme, smooth minimum
phase,  7th order filter clans, native, parallelized CPU. buffer 250ms
Results: processor use less than half than HQplayer, sound for me it's
wonderful, powerful but clean bass, sweet highs, very real instruments,
no dropouts, no clicks or bumps  changing file with different sampling
rate!
A little surprise...
I have tested with my custom USB 2 I2S converter (with XMOS xu216) and
Holo Audio Spring."

I'm wondering whether Roon can be configured to do upsamplaing but at the same time just pass through MQA files the way they are.

Hello guys,

 

I would like to know if there are any known issues with Roon (running on Linux and/or MacOS) with the DAC embedded in the preamplifier Rotel RC-1590. I am interested in playing PCM and DSD64/128.

 

Thanks!!

[pl_svn]

you can ask for a 15 days trial

 

yes: same answer as to the same question you posted in the Audirvana thread 

[acatala]

Thanks for your time, but I have not 15 days trial with the RC-1590.

 

Same answer as to the same question you posted in the Audirvana thread

[pl_svn]

so what you're actually asking is if an RC-1590 will work with Roon (and/or Audirvana): not the other way around

[acatala]

yes, I am, but from the point of view of the player. Simple
