@AudioBang Maybe when the new P2 comes out that will have the option for better clocking (sounds like it will); extract below from Antipodes website: "We are not ready to provide detail on the P2 output modules just yet, but the emphasis is on precision clocking, and regeneration for the range of outputs that an audiophile is likely to want in order to feed their favourite DAC. The P2 providing vibration isolation under the EX, reclocking and feeding the customer's choices of output."

The "super clean" port connects to your streamer (Devialet). If my music server contained all of my music files then would agree, but 1/2 of the music is stored on my NAS in my study, therefore my thinking behind using the clean port for the music server was to ensure no potential 'noise' getting into the files from my NAS. On the other hand I do realise that as my Devialet can now play Spotify, Airplay, etc. then for it to use the clean port would assist with keeping that data clean. Appreciate the other answer is "wait until the EtherRegen is out at try either set-up", but was looking for advice form the knowledge people on here. Thanks John

@JohnSwenson In laymans terms is it essentially you can't properly hear the 0's & 1's for the other noise contamination? As a side question, I have an Antipodes CX Music Server (will be getting it next month), and this will feed my Devialet 1000Pro. The Devialet can (now) access Spotify / Airplay / etc. direct via the internet, therefore if I was only going to use the 'Super Clean' port of the new EtherRegen (when it comes out) connected to my equipment, which one would you recommend? Thanks John

Latest info from Antipodes: Antipodes is sharing one of the new Superior DemoCabins at Munich 2018, Hall 4, W12 with Aequo Audio loudspeaker manufacturers. We will focus on the new X-Series Modular Solution range - the CX, EX, P1 & P2. We are taking this opportunity to officially launch the CX Music Server and to pre-announce the P2 platform. The P2 is being pre-announced very early, so that customers can understand how the new Modular Solutions fit together. The P2 modules will not be available until late in 2018. Please open the PDF brochure below for an explanation of the Modular solutions, and visit our home page for more information on these developments. Antipodes, X-Series-Modular.pdf

@fresponse Ok, so just one sweep measurement per speaker, but how do I do just the subwoofer? Do I play music (or Pink Noise) and disconnect my speakers cables leaving just the sub (assume I also stop all crossover points within my Devialet amps, and disable my HAF Filters within Roon)? Thanks for your help. Cheers John

Thierry Thanks for the offer, I'll take you up on that. Not in an immediate rush as I'm currently having my speakers upgraded (new tweeters, crossovers, caps, isolation footers, etc., etc.) so will have to wait until I get these back (in 2 weeks time) before thinking of doing new measurements. As the Tweeters / Crossovers / Caps are new would also like to give the speakers a good burn in before doing the measurements, but not sure how much this will affect new Filters (looking at getting the Excellence Head filters). Thinking at least 1 month should be enough time, but some say at least 2 months minimum. When doing the sub integration measurements do I do the same sweep measurements required for filters (Pink Noise, etc.), with Left Main, Right Main & Sub as 3 seperate group of readings. Also, I wouldn't have to do the multiple readings required for the filters (is one per speaker sufficient, sitting in the listening spot) Cheers John

Alex Understand if it could compromise your design to keep quiet. That's really generous of you to offer 2-to-1 price, thanks I'll have 88 please On a more serious note, do you think going to my Antipodes Server or Devialet Amp, which would give the best option for the Superclean Ethernet. I suppose when listening to Antipodes I plug that into the SC port, and when listening to internet streamed to Devialet Amp plug that into SC port. I've currently got an Aqvox switch, so assume your EtherREGEN would be a better option than that

Thierry Sorry to be such a square, but how do I go about doing this, as it's sounds from your explanation that this would be the better option. Also can I do this using your tools, or with REW? Cheers John

Thierry Hi again. I asked a few questions on Devialetchat and appreciate your responses. Rather than go back and forth thought worth asking here, as above posters have asked about integration of Sub with mains. I have a 2.1 set-up: Devialet 1000Pro Antipodes CORE music server Lenehan Audio ML5 Mains speakers (2 way floor stander) Paradigm Sub-1 Attached is my current configuration for Sub1 integration with my front speakers via my Devialets. So I have it currently set at High Pass Filter, 80hz cut-off, 2nd Order. Do I need to do anything else other than do my new measurements via REW or your new tool. Also do you think my setting for 2nd Order Filter at 80Hz would be correct (thinking of dropping this down to 40Hz so the Sub only covers the low range). I'll need to get new filters soon as having my current speakers upgraded (same enclosures, but new tweeter and crossovers). Will have to wait a month to let the new speakers burn in (need to get some hours into the new crossover caps), but want to get things in order before I do them (also gives me a chance to try your new measurement tool, or re-do with REW). Cheers John

Thierry Ok, so I gave it a try doing the measurements in REW - 1L & 1R sweet spot, and another 7 each L & R. Still not sure if I've done them correctly, but for the trial song(s) it will give me a good idea of what your filters can achieve. https://www.dropbox.com/sh/g3az7aigjf8deg0/AADuXkqpr-BBPsauK53N3jC0a?dl=0 FYI I normally sit offset from the middle of the speakers and have actually did the measurements with me being offset (1/3 to the left side of centre, i.e. 0.5m from the left speaker axis, and 1.8m from the right speaker). Would you prefer if I did the measurements sitting exactly in the middle? (not where I normally sit) Also could I ask a big favour. I've actually linked 2 songs, therefore would it be possible to do your magic on both of these (they’re a bit different from each other, so gives me an idea with differing types of music). If only 1 song possible then that's ok. Don't worry I'm not going to waste your time, as 100% made my mind up to go ahead and get the full filters package from yourself ("Excellence" option: Filters with & w/o cross talk correction), happy to go ahead with the payment if you need that first. I just wanted you to have a look at my measurements & data, and advise if I’ve carried them out correctly, or do I need to redo them (i.e. sitting in the centre of the speakers, or more accurate with my spacing for each measurement, it was a bit more random for locations for 2 to 8). Regarding the full set of filters, are these generated for all specific sample rates, e.g. 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz & 192kHz (do you do DSD)? Thanks for your time, and looking forward to hearing the songs rejigged. Cheers John PS I've sent you all the info in the comment section of your website.

As I said, dumb question alert - will do the measurements next week. Have a good weekend

Thierry Appreciate you getting back to me. Next week I'll pick a music sample (unsure which will be best), and send it through for the free trial. Not that I'm doubting the HAF correction filters won't work, but will give me an idea of the potential change in sound from the original to your optimised version. Then I'll carry out the measurements via REW (want to take my time and get these right) and can then send through for the full version (most likely will go for the cross talk correction option, then getting the best of both worlds). Cheers John PS Dumb Question Alert - do I need to carry out any measurements via REW prior to sending through my music file for the free trial

Thierry I really like the idea of using your expertise via HAF to produce the required filters, and then it should be simple enough to upload into Roon. I haven't done any sound measurements before (I do have a copy of REW, and a UMIK-1 mic), but am worried that I may not do the best job of taking the measurements, which would limit the effectiveness of the filters you can produce. Is it easy enough for you to see if the measurements have been carried out satisfactorily, and if not advise to take new one's, without having to go through the expense of having to pay twice for a better set of filters (not saying you wouldn't advise, just a genuine question from a newbie). Dumb Questions: 1. Where do I get the Pink Noise file for generating the sound 2. Does it make any difference to taking the measurements if having a 2.1 set-up (2 front mains, with a Subwoofer in the mix) Cheers John
