  1. The images in this article are no longer available. Can someone fix them?
  2. not for mine. for some strange reason. my Terminator firmware didn't advertise any native DSD capability to the USB Audio driver. not even DSD64/128/256. As a result, Ropieee (the Raspberry Pi software) I used didn't allow Native DSD. it was fixed after updating firmware.
  3. I managed to get the latest firmware from Alvin and now native DSD256 works!
  4. Has anyone been able to use a Linux based Roon Endpoint (or any other Linux based streamer) successfully with the Terminator? I am using a Raspberry Pi + running Ropieee and while most things works, I am unable to get native DSD to work. Ropieee supports native DSD with the Amanero board, but the Terminator is not reporting Native DSD as a capability.
  5. That's interesting. I thought it would be the other way around. Have you tried it? can you elaborate?
  6. that's a skewed analogy. it will be equivalent to saying we are driving $50 pair of computer 3" speaker with a $2000 amp. I am hoping most people have more balanced system than that. while i agree that a true review should cater for the general public by pairing amps with different speakers and other components, we are not professional reviewers, just some dude sitting in his cave listening to music. However, having said that, this is more in the tune of a comparison and not an absolute review. So it does show the comparative qualities between the different amps.
  7. Amp polarity is known. The ST10 is supposed to inverse phase, while the Nord doesn't. However, I did try to experiment with phase and I kept them at what is spec'ed. I understand your concern. I have kept all associated equipment the same, same cables, same speaker, preamp. everything. Now I just want to point out that this is just the evaluation in one system, there can be issues with synergy with other component, synergy with the room, etc. I may not be maximizing something coz maybe the ST10 need some cable and mine wasn't the one but that one I have works well with
  8. Yes. the ST10 reverses polarity and it has been compensated by reversing the speaker terminals.
  9. FWIW, here is my brief comparison between a DIY NC400, a Nord NC500 w/ SI opamp, and a unmodified Nuprime ST10 Firstly, between the NC400 and Nord NC500. It is obvious they comes from the same family and shares the same genes. There is no mistaken that. The NC400 is a neutral amp that doesn't color the sound. Many have said it is like a wire with gain. And that's quite true. But it is not perfect. I noticed the NC400 is actually not complete neutral, it tends to lean on the ... erm.. lean side. Bass is good but not plentiful and high seems to be slightly overemphasized.
  10. Anyway. Back to topic. The Nords are in the house. Been running them around the clock for the past 2 days. Won't say much before a couple more days of burning in. At the moment they do sound better than my NC400 but not much. They sound completely different than the NuPrime ST-10. Given that, we should stop lumping all class-D into 1 bucket. They each have their own character and sound.
  11. I was careful to not say that coloring is bad. That's pretty much why we add preamps. Otherwise, everyone will be running attenuated DACs directly into power amp.
  12. Which really begs the question of why. If the Icepower already has an input stage, adding another fixed gain input stage goes opposite of the less is better philosophy. The only explanation is it colors the sound in a more desirable way that is preferred by the designer.
  13. No takers at the moment. Class D is one of those cases where it is possible to gather some enthusiasts into one location for comparison. The amps can potentially fit into backpacks. Imagine asking ppl to bring in their class A amps, it will be quite an operation!
  14. He told me about it before I made my purchase. I didn't want to try something unreviewed so I got the mk1 version. He said there will be an upgrade path.
  15. Anyone who lives in the silicon valley area who has the icepower amps and would like to get together for a comparison we can arrange it. The mk2 of the nord amps also has the pro socket. That's the main change with the matching pro level opamps.
  16. It sounds darker when A/B comparing with my NC400. Everything else are kept the same. In fact, I think the ST-10 beats the NC400 on all categories except for the sparkle at the upper frequencies. It has clarity and transparency, even at the high frequencies, just that it is not as forward. Mind you that it doesn't have the DTSS mods that yours has. from ppl who reviewed it says DTSS opens up the upper end. Perhaps the DTSS mod is where it fixes these issues.
  17. Very interested to know what you think the differences are. Took me a while to decide on which one to get and at this point I am still not sure if getting the SI is the right choice. the Sparkos are $80 each.
  18. Lots of trolls in this forum. I will be receiving the Nords today. Gonna give it a few days of burning in. I also listened to the NuPrime ST-10. Quite impressive, great focus and texture, placement and imaging is so precise there is a great sense of presence and realism. It sounds a bit more dark than the NC400 though, the NC400 sounds more open. I wish I have the budget for the Evolution One, I can only imagine how good that sounds. Maybe I will get to do a 3 way comparison.
  19. I ended up getting the monoblock from Nord. They are quite comparable. They are pretty much just the same ideas with the same components in the input stage (Sparko regulator and Sparko/SI op amps). Interesting that you think the Apollon has better layout, the only difference i see is the orientation of the power supply. they have the opposite orientation and the Nord one ended up with shorter cabling from IEC to PS and from PS to the input stage board.
  20. So it has been decided. I will get the NC500 w/ Sonic Imagery opamp from Nord. And my current NC400 has already been fixed. Super fast shipping from Hypex arrived from Netherlands in less than 2 days and swapping in the new module only took 10 mins. Now it is being burn in around the clock. It will take a week for it to match the hundreds of hours that I have on the other channel. After the NC500 arrives and burned in, I can do a comparison. And I will need to find a new home for the NC400. I am tempted by the ST-10 too actually.
  21. The switching power supply in my computer is technically class D. No wonder it tortures me everyday.
  22. Did a bunch more research online. I am throwing into the mix a couple more amp/modules and my options: - fix Hypex (I already ordered a new module, I need to fix it and in the worse case, sell it) - NuPrime ST-10 - NC500 - the popular ones have either a Sonic Imagery or Sparko opamp input stage - ICE Power 1200AS2 module - this is relatively new from early this year. Most review rank these in par with NC500 at just above 1/2 the cost Tough choice. Wish I can get all of them and compare! These are all in the region of US$1k -> $2k
  23. I agree. Which brings up a point (a bit off topic one), is that sometimes music listening at home is not representative of a real performance. People (me included) would listen to orchestral music or chamber and the bass is full and fills the room. It sounds great and satisfying in the listening room. In a live concert, the cello and double bass don't have that amount of intensity, there is lots of definition, but no way 12 cellos and 8 double basses would shake the whole concert hall. A lot of times, the faithful reproduction might actually sound dull in comparison. I like to use
