Thanks Adrian / @AfterDark.! I have placed my order and already received some of the shipping details. I appreciate you confirming that the Group Buy's Finisar FTLX1475D3BTL SFP+ Single Mode Modules with the Commscope TERASPEED LC-LC Single Mode Optical Fiber Cable will work between my opticalModule Deluxe and Melco S100. Kindest thanks! Des

I appreciate the comments thus far. If anyone has insight into whether the Group Buy's Finisar FTLX1475D3BTL SFP+ Single Mode Modules (with the Commscope TERASPEED LC-LC Single Mode Optical Fiber Cable) will work between my opticalModule Deluxe and Melco S100, I'd love to hear from you... Perhaps @AfterDark.can confirm....? I've read this thread fully and there are very helpful posts from everyone, but I'm not 100% clear if it will work with my opticalModule Deluxe and Melco S100 combo. There had been some contradicting posts initially about it working with the opticalModule Deluxe, but I think it was concluded later along that they would / should work...? I also thought I read somewhere yesterday about two Melco S100's being connected with this SFP module at each end, but I can't find that post now... Insights / understanding are appreciated. Kindest thanks!

Thanks @MarkusBarkus

Thanks @MarkusBarkus - my preference would certainly be to only have to buy one cable. I just wasn’t sure how sensitive a 10M length Commscope TERASPEED LC-LC Single Mode Optical Fiber Cable from AfterDark. would be with being coiled … That said, I would probably have it in about a 2 foot diameter loop

Thanks @lmitche! Great to hear that, very exciting! That actually raises another question I had in mind about the cable length I should order if I proceed.... I ask as... Currently my Melco S100 and opticalModule Deluxe are very close to one another so I use a very short cable. However, I do plan on moving the Melco S100 farther away to sit in my main rack and have the opticalModule Deluxe remain where it is... (I'd likely order a 10M length Commscope TERASPEED LC-LC Single Mode Optical Fiber Cable from AfterDark. as offered in the Group Buy…) I was presuming I would likely need to buy a short cable and upgrade to a longer one when I move the Melco S100, but is that actually the case...? Or, could I buy the 10M length I'd need later and, for current placement, have the 10M long Commscope TERASPEED LC-LC Single Mode Optical Fiber Cable coiled behind the Melco S100 and opticalModule Deluxe...? Thanks!

Hi all - I've been using Finisar FTLX8574D3BCV Multi Mode SFP modules (spec below) between my opticalModule Deluxe and Melco S100 (pics attached as reference). These were purchased through Small Green Computer and are connected with their 100% Owens Glass Fibers cable. This has been working great but I am very intrigued about switching up to Single Mode... ***I am curious if anyone has insight, will switching from my current FTLX8574D3BCV Multi Mode SFP modules to the Finisar FTLX1475D3BTL SFP+ Single Mode Modules (with the Commscope TERASPEED LC-LC Single Mode Optical Fiber Cable in the Group Buy): Work in my situation between the opticalModule Deluxe and Melco S100, perhaps @AfterDark.can confirm.... and Will it bear much of an improvement in sound quality....? IE: I noted a much appreciable benefit between the MMF Finisars that I have now and what the opticalModule Deluxe came with, but is SFP actually that much better than MMF? Currently using - Finisar FTLX8574D3BCV Fiber Optic Transmitters, Receivers, Transceivers 10G 850-NM VCSEL 1G/10G Dual-Rate. Connected with 100% Owens Glass Fibers cable. Thank you, Des

Great point of clarification Ryan. What I’m most curious about pertains to the doubling of max speed aspect you noted. In my case, being able to go from DSD128 via DoP as the max, to “Native” DSD256.

I’m looking forward to Native DSD 265 with my QB-9 Twenty. Was there an appreciable difference with Native compared to using DoP? I’m awaiting the Software update from Antipodes to enable this for my EX, (which utilizes the SonicOrbiter software).

Thanks for the update! It’s great to hear about all parties collaborating and that the code is developed for the QB-9 Twenty, and in the queue for testing. I understand a timeline is not available yet with regard to timing for Antipodes, that said... can you comment if it would be a matter of weeks / months / etc...? I’m very much looking forward to Native DSD. ☺️

Hi vortecjr, I am using an Antipodes server which I understand uses the same sonicorbiter package you have for Sonore. I’ve been trying to get Native DSD up and running on my Ayre QB—9 Twenty which is capable of Native DSD 256, and have been in dialogue with both Ayre and Antipodes to accomplish this. Is the sample format you noted on this post “DSD_U32_BE” still the appropriate one I would want to ask Ayre for my DAC to support, in order for the automatic Native DSD detection to work? Thanks! Des

Thanks for confirming Native 256 CG! I upsample everything to DSD using Roon but am not yet able to play Native DSD, only up to DSD 128 via DoP. I find a balance is achieved in the final 500 hour stretch. The QB-9 certainly hits high in terms of transparency and lack of crud before then. It just seems that the final stretch is where the icing on the cake becomes most apparent, with the presence and emotion solidifying. Thanks for your reply!

Hi CG, I’ve always found 500 hrs to be the point where everything Seems to be truly settled in, and at home. Certainly with my Ayre gear, but with almost everything component-wise in my experience. It’ll get more coherent in the last stretch to 500.... AND that’s where the presence and emotion seem to come in to their fullest. Question - you’re playing in Native DSD 256? Jealous... 🙂

Thanks for your reply Ryan. I look forward to an update and will wait to hear further from you upon Ariel’s return. Much appreciated! Des

That’s great news! Thanks again Ryan. As an update: when I last checked with Antipodes they had connected Ariel with an individual who is familiar with the automatic Native DSD detection in the Linux software used by Small Green Computer and Sonore, (as well as Antipodes). I understand the problem is not in using the QB-9 with Linux kernels, but the QB-9 Twenty firmware’s ability to be detected as Native DSD capable in the aforementioned Linux application. Thanks again for the cross-company collaboration. Cheers!

Hi Ryan, I'll be off on a ski weekend starting today but wanted to acknowledge your response. I'll review the details later but wanted to share my setup details in Roon. I only use Sample Rate Conversion, with settings as per the pics attached. I experimented with Parallelize Sigma Delta Modulator but found it best turned off... It killed the life in the music and made it more forward sounding, almost loud/shouty... completely lost its sense of ease, and killed the subtleties within the soundstage. I also wanted to clarify - my enquiry was regarding Native DSD 265. You and I have been in email dialogue regarding it not working (yet) with my Antipodes EX. We had not yet conversed regarding potential resolution. Cheers, Des
