![]() ![]() Last, there is the question of replacing the Topping audio drivers on the PC with the MiniDSP's drivers. On a smaller note, this would also require pushing the MQA processing back to the Tidal software on the PC. This seems like the simplest solution but I hate the idea of losing the D90. Here are the 2 options that I was considering.ġ) Remove the D90 altogether and let the MiniDSP handle the PC USB input and DAC duties.then directly feed the Mini analog output to both the E40 (high signal) and the Sub (low signal). But, going down the MiniDSP SHD road raises the question of how to hook it up. The other advantage of the MiniDSP SHD seems to be the ability to apply corrections to the M105s and Sub independently. (knowing that I could later add Roon and define the MiniDSP as an endpoint). I thought about Roon (which helps solve the larger whole house problem) but I'm not quite ready to go down the full Roon approach just yet and, instead, have been eyeing adding a MiniDSP SHD to provide DSP/Dirac support. Its great combination but none of those components comes with DSP support. i7 based Windows PC -> Matrix Audio USB board -> Topping D90 DAC (MQA version) -> Keces E40 integrated amp -> Revel M105s and a Pinnacle Sub (I am also looking into replacing the sub). I also do some casual listening on Spotify and Youtube. Music is sourced from a PC with most critical listening coming from either Tidal or Media Monkey playing FLAC files located on a Synology NAS (mainly std redbook CD RIPs). Some details.That system is located in a small/mid sized room (14x14) and is a nearfield setup on a large desk sitting in the middle of the room. I have a couple of systems where I will want to add DSP eventually but I'm currently focused on my office system that I use for most of my audio listening. I'd like to get started with DSP but need to figure out how to add DSP processing to my system(s). Further updates will not bring any improvement other than Tidal connect, maybe memory consumption will be optimized, but I do not expect significant major changes.Newbie - so feel free to point me elsewhere if there are existing topics/threads that address this. I have the impression that the R26 streamer is designed especially for Roon. Theoretically, Gustard could prepare two versions of the update: one for Roon users and the other for non-Roon but Tidal users, etc.Īfter all this, I even bought a Munich M1T but eventually returned it because for the same money or even less I will buy a lifetime Roon license and I will not need a separate streamer. BubbleUPnP, Linn Kazoo, Linn app…) without a BubbleUPnP server. This is a compelling advantage because you can use (e.g. If Roon is not in use it is possible to disable Roon Bridge and save 30MB of RAM.Īdditionally, I found that in nf you can enable Open Home Renderer. I also tested Tidal connect, it uses a lot of memory but it works. A special application inside the R26 streamer - Roon Bridge, made rather by Roon programmers, is responsible for playback. R26 uses about 50% of memory and plays HiRes flac and DSD without problems. ![]() ![]() I haven't used Roon yet but installed it on a Synology DS220+ and I'm surprised how it plays. In addition, information about decoding the DSD file is not displayed and the 1-bit decoder will not work. With Media Render configuration in BubbleUPnP "Decode Audio to PCM for: All audio formats + constraints below" HiRes flac files play without stops but there is a problem with DSD playback because DSD64 files are decoded with a sampling frequency of 352kHz, DSD128 with 764kHz and DSD256 files are up to 1.4MHz and this is too high. I updated mpd player to the latest version but the result was even worse. "alsa_output: Decoder is too slow playing silence to avoid xrun" So I logged in via SSH to R26 and when playback was stuttering, memory usage was at 100%, this is what I saw in mpd.log: So this would workaround any eventual flaw in the HiRes FLAC decoding of the Gustarender." If you set "Audio decode is PCM for: All audio formats + constraints below" this makes BubbleUPnP Server convert input audio to WAV (with no loss of quality) It is possible its FLAC decoder has a problem with HiRes (assuming you can play 44.1/16 FLAC fine). "The log shows that your Gustarender is becoming unresponsive to UPnP commands just after being instructed to play a 96 kHz / 24-bit FLAC from MinimServer. I thought it was a BubbleUPnP problem and wrote to them and attached the logs. I also had trouble playing 24-96 and 24-192 files via BubbleUPnP server. ![]()
