High jitter (from aggresive DSP ???) - cos2012 - 30-Sep-2019 Hi everyone, I bought myself a reactor 600 after intensive research. The conclusion that i found is that reviews for speakers are useless !!!! The biggest problem i have with it is very high jitter on certain tracks. Those tracks are not listenable on the reactor and i believe it is due to the aggressive dsp. I tried using all types of connection - Bluetooth, airplay, optical and jack input. Same thing I believe that with further updates it can be corrected. I listened to FLAC tracks from pc through a DAC with optical connection and analog jack (tried both). Also tried listening to a cd-player through optical output. I have 2 units, one Marantz and one Pioneer. It is the same so the signal is not the problem. The processing is ! I will post links from youtube so it can be easier for all of you to test for yourselves, some of the tracks that i noticed to induce jitter You can play your own hi-fi flac tracks or original cd's, some youtube links have very poor quality. But the links are good for example purposes here you can notice that when the battery comes in, the voice is a being recessed. It is not dependent on volume, it's as if when the bass comes in the voice is subdued. This led me to believe its because of an aggressive DSP in the internal amplifier https://www.youtube.com/watch?v=_Y2qfmjCmCw The beginning of this track is like a normalizing failure https://www.youtube.com/watch?v=j2PYEEMXREU On this one, it can be easily noticed from the 2nd minute https://www.youtube.com/watch?v=eQbg4ijqhHY here you can notice it from the 1:10 mark https://www.youtube.com/watch?v=_eXiy_NDlmg another track that sounds like it's poorly normalized https://www.youtube.com/watch?v=rZjm-lHqXQk another one, at the 1:20 mark when there's a chorus in the background. The chorus is very jittery and seems poorly normalized https://www.youtube.com/watch?v=_xlwyil6dCM&list=PL2802EAC127766032 RE: High jitter (from aggresive DSP ???) - ogs - 30-Sep-2019 I doubt this is 'jitter'. DSP use do not create jitter. The lower mid range of Reactors is a bit recessed, but it's not a variable thing. If it does vary, it is more like a 'late-night-mode-compression' (like ICM-Intelligent Cinema Mode on Experts) if there is such setting for Reactor. Are you using just one Reactor? RE: High jitter (from aggresive DSP ???) - Snoopy8 - 01-Oct-2019 Welcome to the forum. Please check whether night mode has been not been accidentally enabled. (Sorry, cannot guide you further as I have Phantom Golds and it uses the older Spark App). RE: High jitter (from aggresive DSP ???) - cos2012 - 01-Oct-2019 Thanks for the quick replies. I have only one reactor unit. I cannot find the night mode option in the app. Do you guys know if reactors have this option? Can you please guide me to it? It indeed sounds like a volume leveler is applied.

In the Spark App which I am using, it is a moon symbol on right side of the volume display but I cannot see an equivalent screenshot for the Devialet App. Suggest you contact Devialet support who are usually responsive and helpful. RE: High jitter (from aggresive DSP ???) - ogs - 01-Oct-2019 If there is no night mode I may have misled you. I do not own Reactors so I'm on thin ice here.The only other thing I can think of is artefacts from summing to mono. The Youtube samples you provided all sound fine to me in stereo. RE: High jitter (from aggresive DSP ???) - ogs - 01-Oct-2019 There is also a possibility that your Reactor is broken... any chance to borrow a new reactor from your dealer to compare? Or maybe bring yours to a shop? RE: High jitter (from aggresive DSP ???) - Haytera - 01-Oct-2019 (01-Oct-2019, 06:24)cos2012 Wrote: Thanks for the quick replies. There is no bass reduction (night mode) on Reactors RE: High jitter (from aggresive DSP ???) - cos2012 - 01-Oct-2019 (01-Oct-2019, 10:48)Haytera Wrote:(01-Oct-2019, 06:24)cos2012 Wrote: Thanks for the quick replies You have two reactors. Can you listen to the tracks i gave and see if you can hear how strange those sound? It would be nice to know my unit is not defective.
