  1. I might have gotten it wrong, but I'd prefer the big dog to weigh in on the effect of the GPU for pure upsampling modulators and filters on his software, without room correction or other DSP plugins. In any case, I'm looking forward to those new Nvidia 3090 TIs to release so I can buy one up and see if it makes any difference.
  2. I wasn't sure if you were kidding or not. FYI to anyone else who didn't know what tthe HSA-1b was, it's another dedicated, direct drive amp for the SR1a, but it also has outputs for a standard dynamic or planar headphones too. Certainly makes it more interesting. I'm excited to see these dedicated amps coming out for the SR1a. Hopefully Schitt has some competition soon or they just might take up all the orders themselves.
  3. Haha, I figured it had to be in there. I read over it once again before posting, but I guess I didn't give it my all. I did go find some pictures, just FYI for anyone else wondering what $3,900 is going to look like from RAAL for a dedicated amp:
  4. That's quite the rave review, Chris. I am one of those fence sitters for the SR1A, but we'll see how that goes down the road. I want to head further down the Abyss AB-1266 Phi TC path for a while before thinking about the SR1A and maybe the Jotenheim R. You mentioned that the Jotenheim R is ~$3000 less than the nearest direct drive/no RAAL Interface Box amplifier, but I'm not sure what product that is not how the performance compares. Could you tell me the model and if you've heard anything about it?
  5. Can you PM me about that too? John was one of the first guys I bought something from about 10 years ago. He provided great service and great sounding gear for the money. That'd be terrible news if he's decided to throw the towel in.
  6. Looks like a hit and run by the OP. I thought the ad was ridiculous when I read it. I wasn't sure how whoever thought it up was going to be able to realize any capitalization on the COVID-19 topic. It's too dumb to even talk about, yet I also talk about it? Marketing success! Maybe the angle was an OCR hit from a Google search for both audio AND COVID-19...? But I wouldn't fan these flames any further. I'd open my own thread if I actually disagreed with this enough to bring it up.
  7. For HQPlayer, the CUDA offload helps out for optimizing convolution filters for things like DSP room correction. It doesn't directly help with music upsampling. For the upsampling part, getting the best performance requires the highest 2 core clock speed you can get. More cores doesn't really make a big impact. The CPU with the highest 2 core clock speed is the new i9-10900K at 5.3GHz, if you're lucky. 5.1GHz for sure. Compared to the recent i7-9900K, it's probably a very close game. But in either case, neither can yet run DSD512 at the highest HQPlayer settings/modul
  8. Not that the method is the same, but separately and directly powering the ram was a top flight modder's mod back 4-5 years ago on the JPlay forums. Everyone who did it said it was a critical mod, but I never saw it catch on with any "commercial" music PC offerings and it seems to have drifted out of the limelight now. I always thought it was an interesting sounding mod. [/edit] I followed the link, Sligolad, Nige2000, and some others. Those are all the same guys that were blazing that trail on the JPlay forums before. Even if back in 2018, nice to see they're sti
  9. I'm not trying to say I'm the authority on this, but I have used this Streacom FC10 chassis in 4 different builds and it's always delivered effective cooling results. As you can see from the internal picture, there is 0% milling into the side panel to improve conduction or heat transfer from heatsink to heat pipes: The heat pipes have been flattened where they interface with the side panel, riser, and CPU block. I think milling grooves is cool, but from my experience so far, it seems unnecessary in order to deliver cooling up to 95W TDP.
  10. I see your point, but I wouldn't count them down and out so quickly. We could easily request thicker stock. Besides that, it'd only be a 1-2mm groove, not 3-4mm. The Takachi side panel heatsinks are similar to the Streacom FC10, which handle up to 95W TDP CPUs. If we could use 1 panel/side per CPU, that may be enough. And if not, we could explore thicker panels or copper. I am in China now, so I will see if I can source a copper drop-in heatsink replacement for whichever case we end up with. I don't think it'd be too much here, but I could be totally wrong.
  11. I don't want to crap on the direction of the thread, and it's possible that across one of my multiple readings of the thread I may have missed it, but why not consider a Takachi Enclosures case? They are a professional case Maker from Japan and they make the chassis for the UpTone JS-2, the Taiko servers, and many other audio products. They have top notch quality, they take custom orders, and if you start with one of their existing base options and modify it, you can save a lot of money while still getting basically what you want. Another benefit is that they make the
  12. For that, there is the one and only Titans Audio Helen. The only D/D that does I2s in->I2s out, that anybody knows of. So the whole flow there would be: 1. Terminator Plus Master Clocks->Gaia. 2. USB source->Gaia. 3. Gaia USB->Gaia I2s. 4. Gaia I2s out->Helen I2s in. 5. Helen I2s in->Helen I2s out. 6. Helen I2s out->Terminator Plus I2s in. Music. That chain gives me a bit of a laugh, mostly because I've never heard of a DAC sending Master Clock outputs to an upstream device... Maybe I'm behind the times in the Ext
  13. Good for you for spotting that one! I had to read to basically the last page of the new Terminator Plus User Manual to find confirmation that that was the usage for the "clock out" function! And it's exactly as you said, the Terminator OCXOs are used as Master Clock inputs for the Gaia, or the new Avatar CDP. It's definitely got an "ecosystem" feel to it, but on the other hand, Denafrips did open up their I1s configuartor to anyone, so they've been pretty open in supporting other standards for the end user/owner. I think the overall approach sounds cool, but not sure if it's bette
  14. I'm still wondering what the deal is with the clock inputs. Whether or not Denafrips has their own clock in the works, ( @alvin1118) I wish there was a bit of info about where someone could get an outboard clock at these frequencies that would likely beat the built in ones. The frequencies aren't "strange" as far as internal clocking goes, I've seen them both for the 5-7 odd years I've been eyeing clock mods, but they are not mainstream for input clock frequencies. I think the SoTM txUSB and SCLK-ex are the only normal, audiophile "master" clock sources I know of that output the 4
