  1. The "Official" Aurender Discussion Thread

    Probably several different threads about several different tweaks! one new thing is to place the Ethernet cable for Tidal into its own Netgear GS105 (V4 or V5) and have the “in” going to port 5 and the out at port 1 AND then to ground the SMPS 12V power supply to the same AC outlet or strip (this apparently fixes leakage current from getting in via the Ethernet cable to your system. Search for SMPS Grounding. Another is to galvanicly isolate your Ethernet with either a passive Medical Ethernet isolator or with a cat 6 to optical to cat 6 Extender. Search for “a novel way to massively increase sound”. For ethernet cable , either the higher end Audioquest, Nordest, or the copy of these made by Ghent audio seem to be popular choices. So far I have the Ghent Audio Ethernet cable and the Basske Medical Gigabit LAN Isolater and I just installed the Netgear GS105 (V4) now I need to try the grounding “hack” for the SMPS DC cable , which I plan to make and try today. I think so far what I’ve implemented seems to help make improvements for Tidal and also for even locally Autrender stored playback. I also noticed that when I removed the Ethernet cables I had going into my TV and Pre/Pro and OPPO Blu-Ray player and when I temporarily disconnect my Amazon Fire TV from my system too, that I got a big improvement in sound quality. I suppose that this means there is AC / DC leakage current and ground issues running through the Ethernet cables in my system? Give these tweaks a try!! None of them are that expensive (the Audiophile grade Ethernet cable being the most $) and none of them will hurt anything!!
  2. SMPS and grounding

    Hi, so I’m just digging out a bunch of my unused gear and I have a GS108E V2 (the managed “E” version) and a GS105 V2 and a GS105 V4. Seems like from this thread that I should only trust the GS105 V4 and the two older V2’s (108E and 105), I should not use ?? Also, If I’m understanding this correctly, if I shunt and use that one V4 that I do have and connect only the BJC Cat 6a to my Aurender N100H, I would be okay anyhow? I do also have an Amazon Firebox that has LAN cable that is connected into my Pre/Pro. Would it be okay to also connect the Amazin Firebox into that one V4 or shall I dedicate one to only the Aurender and buy another newer V 4/5 for all my other devices? As of now, only the Aurender and the Amazon Firebox are both connected to my audio system that also have a LAN cable. However, I recently purchased a Synology NAS and may soon start using that to play albums stored on it via the Aurender N100H also, so should I also connect the Synology NAS to the shunted GS105 V4? Thanks !
  3. First: SACD-ISO library AND DSD library: 1. I too convert all SACD ISO to Stereo (2 channel) DSF. * I have an Aurender N100H with an internal HDD that I use for most playback: 2. On (internal HDD) My Aurender N100, I only store the 2 channel DSF, NO SACD ISO’s. 3. At least 50%-60% if my SACD-ISO’s have both 5.1 DSD and 2.0 DSD mixes. Thus, at some point in the future, I believe I will have and maybe most of “us” will have 5.1 DAC’s. So, in the future I want to be able to use the original SACD ISO to create a 5.1 DSF version. 4. I also believe it’s very important to maintain an archive (the SACD ISO) of the DSF not only for a bit perfect backup, but also as an example, I encountered a DSF album I had on my Aurender HDD the other day with a track (song) that was corrupted. I was able to go back to the SACD ISO and Re-Convert the album to stereo DSF again, and it was fixed! If I did not keep backup copies of my SACD ISO’s, I would not have been able to do this! Last, I also have an OPPO BDP-95 CD/SACD/Blu-Ray Player. I am able to burn copies of the SACD-ISO’s I have to dual-layer DVD-R discs and play the 5.1 version using the OPPO as the player and my Integra 11.4 Pre-Pro (it actually has 5 channels of internal Sabre 9028 DACs and plays Native direct 5.1 DSD, so it’s not what I use for 2 channel listening (I have a Mytek DAC I use for stereo), but it’s not bad at all for multi-channel 5.1 DSD. AIFF and FLAC: This is honestly less clear to me and I’m not 100% sure it’s necessary! My Aurender plays WAV, DSF, DFF, AIFF, ALAC, FLAC, mp3, MQA, etc. (So does my DAC). So, I only keep one copy on my Aurender internal HDD (same as I only keep DSF on the Aurender also). When I first started all this “computer audio”, about 2 years ago, I first read Chris’s Computet Audiophile ripping guide. He suggests, when ripping a CD via dbPoweramp to automatically make a WAV, FLAC, and AIFF version of all CD’s ripped so you have a true WAV copy for archive and FLAC and AIFF copies for playback, etc. I decided from the start to skip the WAV since I thought AIFF is very similar to WAV, but it can hold Meta Data and be tagged. So, for all of my ripped CD’s, I have an AIFF copy and a FLAC copy. As of now, I keep 2 backup copies of every CD ripped in both AIFF and FLAC, however on my Aurender’s internal, I just keep the FLAC version (takes up less HDD space). I do also have a lot of HiRez digital downloads from HDTracks, Quboz, Pono, etc. and some of them are FLAC only, some are AIFF only, some are ALAC onky (I’ve experimented a bit trying to decide which version of HiRez download sounds best but it’s not easy to tell much of a difference), however this an additional reason why I have separate “AIFF” and “FLAC” folders for my digital music backup copies. So, I’m 100% convinced that it’s very important to have both a DSD (DSF) version and the original SACD ISO version for all of my SACD / DSD backups. However, I’m not really sure if having both AIFF and FLAC versions really is necessary? It could be I’m just wasting Hard Drive space and that all I need is AIFF only ? (I think if I had to choose between FLAC only or AIFF only, AIFF makes more sense since it is more “true lossless” vs. FLAC, it can store Meta and Tagging and Art, and it can be converted to FLAC at any time (although it’s definitely time consuming to convert AIFF to FLAC, so it’s convenient to have both versions stored, but at the cost of almost double the required storage space). Please let me know your thoughts (or anyone else) in regards to my backup and storage methodology. I’m definitely not convinced it’s the best, just what I’ve been doing. Also, the synology CloudSync to Google Drive is an absolute worst case scenario backup, because it takes soo much time to upload and download to and from Google Drive, it’s not actually practical for “real time” backup vs having a local backup copy on a NAS or external HDD’s. I plan to purchase a second NAS to backup my primary NAS some time in the future, but since I just recently purchased my first one, I need to wait a while to save up additional funds:)
  4. @foodfiend Thanks for your advice! As you may see, my post was 8/7/17. I actually purchased the Synology 916+ w/ 4 8TB WD Red drives running RAID 5 around 9/1/17. At the moment, I’m backing the entire NAS up to a Google G-Drive using the included CloudSync SW. I also have two external 8TB HD’s on-site that have a duplicate copy of all the music currently on the NAS. I also have three 4TB external drives with another 11TB’s of music on them that I have not yet copied over to the NAS (I’m slowly but surely working on trying to get it all organized and “cleaned up” before putting it in the NAS). I also have a total of about 40TB’s of music on the Google G-Drive (16TB’s are the NAS backup, the other 24TB’s are a mix of what is on the three 4TB’s not yet on my NAS and then about 15TB’s worth of live music (concerts), which I’m not interested in keeping on my on-site NAS or even having a back-up copy at home of. Since I have a Google G-Suite account, I have unlimited storage at the moment (I fear this will change in the future), so I just have been storing any live concerts or bootlegs directly to the Google Drive, but I don’t really listen to that stuff often and if I lost all of it for some reason, I would honestly care less. I’m now ready for stage 2! I need to get a more formal on-site (or remote as in bank or relatives home) backup of my NAS using the included backup SW and I need to hurry and get the remaining in-organized 11 TBs remaining on external drives onto my NAS. (It’s been slow because it’s really time consuming! I’m slowly working on getting all my music (27 TB’s!) into a organized database such as: file type- AIFF FLAC DSD SACD-ISO and then by genre under each file type. This may end up being impossible to ever finish! I do have the 16TB’s on my NAS already sorted and organized into this (it makes managing a large music collection much easier!! ) thanks for all of your advice and help so far!
  5. Offline Upsampling

    I have The Filmore and People, Hell and Angels (The Filmore sounds fantastic). I believe that this is a 2008 Blue Spec Japanese hybrid SHM-SACD, which is now out of print and was a limited run. (that’s the only SACD version/ release of this album I could find, however since there’s is no tags or meta data on the 5.1 DSF I have, I’m not ruling out the possibility it could be a bootleg, it’s definitely possible).
  6. Offline Upsampling

    Thanks, I did see that online, unfortunately, The $249.99 USD cost of the PROduce-RD version is a little expensive just to convert 1 album (I'm sure I could find some other uses for the software, but overall, I use ISO2DSD and dbPoweramp and 99% of the time they provide me with everything that I need to convert SACD ISO's and to tag and Meta data/ album art for DSF files). Thank you!
  7. Offline Upsampling

    Unfortunately, I do not have the SACD ISO for this album, only the 5.1 DSF file. if I had the ISO, I wouldn't need to convert 5.1 to 2.0, I could just use ISO2DSD from the ISO to convert to DSF Stereo. This is Jimi Hendrix - Electric Ladyland
  8. Offline Upsampling

    Can your software convert a DSF 5.1 album to DSF 2.0 (Stereo)?
  9. The "Official" Aurender Discussion Thread

    Thanks for the info! I did not realize Aurender had a new update to the app! I will download it and report back to let you know if this fixes the iOS 11 bugs!
  10. I could not find discussion regarding this topic in the archives, so I apologize if it's been discussed before! I have a DSF 5.1 album (DSD) and I want to convert it to DSF Stereo, I was hoping this could be done using dbPoweramp's conversion software, but it is not an option (I could convert it to 2 channel FLAC with dbPoweramp, but not 2 channel DSF). Anyone know what conversion software will allow me to do this? Thanks in advance for any help!
  11. The "Official" Aurender Discussion Thread

    I think it’s more of an Apple issue than Aurender, overall the iOS11 updates for the iPads have been very buggy all around, not only with Conducter. The iOS 11.x for the iPhone seems more stable than on the iPad.
  12. The "Official" Aurender Discussion Thread

    I have an. 100H and since upgrading to iOS 11 it’s been very buggy!! Lots of freezes and long pauses, I have to constantly quit the conductor app and then reopen it. I would say that you’re best off staying in 10.x for now, I wish that I never updated!
  13. The "Official" Aurender Discussion Thread

    Actually I would really be interested in participating in this “Shoot-Out”!! I have an N100H and I just recently purchased a Synology NAS and have been even contemplating if a uRendu may be a better option vs. the Aurender to play music from my NAS. I have the Aurenders HDD full at this point and would leave that as is and potentially use the uRendu for NAS playback so I would not have to worry about having a duplicated music library within the Conductor App. I’m located just on the other side of the Ben Franklin Bridge in Philadelphia (Old City). Lets PM each other and discuss the possibility of a shoot-out
  14. The "Official" Aurender Discussion Thread

    Thanks for the info! I did fear the duplicates! Such a pain! I don’t want to delete anything from the internal HDD, I definitely suspect that the SQ must be better playin from onboard HDD vs NAS since it’s eliminating a bunch of external factors the NAS introduces to the playback chain. I do however want to be able to play music that I can’t fit on the internal HDD without having to constantly swap albums in and out of the internal HDD. I know a lot of the Sonore uRendu users have discovered an increase in sound quality using an LPSU and also using Ethernet LAN Isolators or fiber links and also using Audioquest type higher end Ethernet cables. I suspect similar tweaks would help SQ with Aurender too, but obviously have not tried yet
  15. The "Official" Aurender Discussion Thread

    I have a ton of DSF albums in DSD 64 and all appear fine. Its only the DSD 128, DXD, and .DFF albums that don’t appear. (All tagged the same methodology). I will say that in regards to Wikipedia issue, I’ve noticed that it definitely does not work with any album that I have custom tagging for the album title,so that may be the issue? I have a ton of albums where I have a CD rip, an HDTracks 24-192, a JAPAN SHM-SACD rip (DSD), a Vinyl to 24-96 rip, and a USA MFSL SACD Rip, etc. So I usually notate the version of the album in parentheses in both the folder and the meta tagging. Example: “The Rolling Stones - Sticky Fingers - (2010 Japan SHM-SACD) - [DSD] “
