Greetings!
Today at 3 pm EST will be the weekly meetup. So, crack open a beverage of choice and join us.
As always, if you are having an issue, want to ask questions about Roon, or other hardware/software audio topics, or just chat about music.
Please keep in mind, everyone here is a fellow user like yourself; so this is NOT an official Roon chat.

Apologies,way too busy I’m afraid catching up with honeydew lists and such.
@Rugby had to leave just shy of the hour so I’ll summarize the musical selections for this week.
At the top of the list, and in response to a discussion around the history of Fripp & Eno Live In Paris, @andybob reminded us of this little bit of history at the first showing of Stravinsky’s Rite Of Spring.
The Riot At Stravinsky’s 'Rite Of Spring' Premiere |.
Other things @andybob is listening to include:
@Ernesto_Del_Aguila is listening to:
@Peter_Bruderer is listening to:
@Sloop_John_B is listening to:
@David_Mader is listening to:
a bit of bosa nova… flor do milênio
YouTube Music
and also reminded us here in the states, PBS has some excellent documentaries behind the making of the music.
@Rugby is listening to:
@ipeverywhere (hey! that’s me) is listening to:
Other topics of discussion, apologize I am not giving credit here on who brought this up…
and a whole lot more… see you next week! where we might discuss…
Who would you rather see Roon Labs partner with? Apple Music or Bandcamp
If I missed anything I’m sure someone will put it below.

Not going to be able to make it this week
The Esther Phillips cover of ‘Use Me’ is on her 1972 album ‘Alone Again Naturally’.
Also, David, your interest in The Pretenders is excellent. Great band. The Chrissie Hynde - Valve Bone Woe solo album would be right up your street.

Sorry we got booted guys. great chat.
My Pick for the Week in honor of Good Friday and Easter is …
Remember not to clap until after the 2nd Act.
When you get your Cyan2, use Roon’s filter choices and DSD upsampling to see what you can/cannot hear.
I’ve been listening to this new album by Reyna Tropical - Malegria. Its Latin indie with a little tropical vibe
Also, hard to escape Beyonce. Not really a Queen B fan but I like this new one Cowboy Carter. Third one that got heavy airplay is Dune 2 soundtrack
Not enough hours in a day I’m afraid when I’m on these short weekends at home😕
This week I listened to:
Black Rebel Motorcycle Club - Take Them On, On Your Own
From 2003. The Second Album. I actually prefer it to the first. Didn’t really get into them when it was released, but enjoyed it this week while walking. Effects powered riff driven rock. A bit shoegaze and even a bit ‘gothic’, whatever that means.
Jim Moginie - Red Continent, Murmeratiions.
Two 2023 releases featuring the Midnight Oil Guitarist/Keboardist. The first with Rob Hirst and its very late Midnight Oil in its topics and song structure. The second is solo electric guitar, slow chordal progressions, clean sound.
Jim has released a book “The Silver River” which is about his life and influences. Two notable early influences are Jan Akkerman and Black Sabbath.
If you haven’t heard it, I would highly recommend the first Midnight Oil album, I think from 1978. Self titled but sometimes called ‘Powderworks’. It is a wonderful pastiche of styles and quite unique. The recording was a bit thin on the bass, but the songs more than make up for it. Ultimately I would call it a prog album, but it is a very approachable pub-rock style of prog. It was followed by the second album, Head Injuries, a more direct rock album, but still with some prog flourishes. Although I like their later stuff, these two earliest albums are my favourite Midnight Oil stuff, possibly because that’s what they played when I first saw them.
Absent again, alas this time due to picking up the mandatory bug on a long haul flight….one day…
Based on the year this was released I started trying to identify if there was a “standard” way of applying the RIAA eq in Roon… that lead me to HQP… but never a definitive answer.
Anyway, I’m wondering how many digital releases are sitting out there as the “vinyl” master expecting to be played back through a phono pre?
Was there a consensus opinion on those settings? I find them quite good.
Ah, no. Serveral fellow users had never seen hqplayer and could not grasp when I mentioned filters and modulators, so I posted a list for them to look at.
In our chats we talk a bit about DSD vs. PCM and the role HQP plays by offloading the “filters” and “modulator”. I finally found a simple diagram…
Now, this diagram is relevant on the PCM side for almost all chip based DACs. It works a bit 9see what I did there) different for ladder and FPGA DACs but…
*see source
The top diagram is PCM. An oversampling chip DAC will take the multibit PCM and convert it to 1 bit SDM. It first runs an oversampling operation which is the filter and then it passes it through a modulator to convert the multibit PCM to 1 bit SDM. HQP can perform both of these things and pass the 1 bit SDM directly to the DAC.
Once it is 1 bit SDM you get the diagram below where the 1 bit SDM is just de-modulated to voltage on the analog side.
Some DACs have various filters you can select or you can use Roon’s built-in filters. But, they are limited. An additional limitation is the processing power in your DAC. All filters work on samples and the number of samples makes a difference in the “accuracy” of that filter. DACs don’t have a lot of processing power so they work on very few samples, or taps. A paper on this I commonly reference from Watts (of Chord DAC fame) identifies why “a million taps” is the right number. While Chord believes PCM is superior to DSD, anytime you convert PCM to DSD it still needs to go through an upsampling (or oversampling) filter on the PCM side. So, the paper is still relevant even if you’re using HQP to convert to PCM to DSD. Of course, HQP has filters well beyond a million taps. Here’s the paper https://chordelectronics.co.uk/wp-content/uploads/2018/07/The-theory-behind-M-Scaler-technology.pdf
Anyway, we can chat more if it comes up again. See you all in a couple hours.

Not all PCM DACs are delta sigma DACs so the PCM line would be different me thinks.
