I hear a difference: the sound becomes thinner rather like skin stretched after a face lift.
When I press the NOS button I do not hear any immediate difference at all but after a while the change is clear.
I read that Denafrips will soon be updating their DSP unit for the Terminator.

Do you have more info about this DSP’s upgrade ? What is the Terminator’s DSP really doing ? Will this DSP’s change modifie the Sound ? Can it be a juste a firmware upgrade or should it needs a (painful) hardware change ?

PS: I also heard no différence with NOS engaged or not, but I tested with rapid A/B changes. I will try again with longeur periods between mode change.

I hear no difference either in my speaker setup. Never tried it with headphones.

Look at post #292 and following on this forum.

I hear a difference but prefer it off. Interested in the DSP when it comes out.

Same here. Prefer it off. I use the upsampling in Roon.

Does this mean you prefer NOS mode off (OS mode on), and sending upsampled file from Roon to Terminator's input so Terminator will go through upsampling once again?

Hi,
Neither do I. No difference at all between NOS and OS. I just left it with the light on. LOL.

I hear no difference when selecting NOS but all the reviews make it seem substantial. Does anyone else hear essentially no difference?

Yes, definitely a difference.. OS is more dynamic and introduces some roughness/edginess to the treble - not as smooth. Doing oversampling in your computer/streamer and running NOS on the Terminator produces a smoother (yet slightly less dynamic) sound. I'm curious to see what the next iteration of the Terminator's DSP will sound like. I run NOS unless my incoming signal has to be 44.1k (TV in my case), and then I use OS to avoid rolled off treble.

Light on = correct in my opinion unless your incoming signal is 44.1k.

 

[johnzz4]

Does anyone else have dropouts with a 192k input over AES? I haven't experimented enough to figure out if it's my streamer or the Terminator, but over the course of a song, it drops out for a few seconds. It's repeatable too, the same few seconds of each song if I search to that part of the song. So bizarre. No issue with USB. 88k input over AES is fine.

No. I upsample from roon only. I have NOS on the Terminator - light on.

No. I upsample from roon only. I have NOS on the Terminator - light on.

Thank you for the clarification. I am in a process or ordering one and I will be using HQPlayer to do the upsampling.

Hi Johnzz4,
I don't like to upsample even on ROON. All DSP is off. What do you recommend? Light on or off? To me, they both sound the same. My Termy is connected to Simaudio 430HAD via Gustard U16 is2 HDMI connection.

I have HQ Player but it does not seem to go well with Roon. It keeps crashing. Maybe my MBP is not powerful enough.

That is interesting. I have been using Roon+HQPlayer for few years without any issue, and the recent release of version 4.xx is even better, when upsampled to DSD512.
