  1. Good on paper but not so good sounding when you try them.
  2. Just to avoid any speculation, there is NO "large amounts of capacitance post the voltage regulators" used here. I guess great minds think alike :). To he honest, I never opened or looked inside a JS-2 :). I came across those chokes during the development of the DIY unregulated power supply for the Taiko ATX. Emile from Taiko recommended them to try. Those chokes contribute very little to the ARC6 magic, but they do help. I've had everyone who got my prototype power supply listen to it with and without the chokes to confirm (in different systems) if it's worth using them.
  3. I have to agree that digital crossovers is an excellent application for digital room correction. Since there is already DSP involved, it does not hurt to add room correction. No concerns from me doing it this way. There are many benefits of using active crossovers. In fact, thumbs up for those implementing it this way 👍. Let's give credit where credit's due :). I don't think that's @Zaphod Beeblebrox's intention. From my conversations with him on this topic he does not have the time and does not want to deal with measurements and room corrections, but he is open to add thi
  4. @StreamFidelity I expect that at least 90% of the people here will disagree with me. It's a controversial post that will piss off some people. I've done it before and I am sure I will do it again :). Hopefully, my post will not derail this thread too much. You definitely fall under a different group of people than the group I meant. You are in a group that recognizes the importance of the digital source and you spend quite a bit of time on R&D of your digital source, but you do it on a much tighter budget than people like @romaz. No question you are much wiser than us on how you
  5. I don't know a single person with a reference system of the level of @romaz or better who liked digital room correction. Not a single person. Why? Because at this level absolutely everything matters and makes a huge difference. I visited @romaz and listened to his system last month, so I have a pretty good idea of what it does. I've heard those Wilson Alexia Series 2 speakers you see on his photos many times before but never as good as they were in @romaz's system / room. And in a system of that level, digital room correction done the traditional way makes a lot more bad than good. This
  6. @Juice Hifi - can you please share what your reference audio system consists of?
  7. @GoldenOne - are you based in the UK? Sean Jacobs will build you a demo DC4 LPS for your DAVE DAC to try if you are interested. My take on the DAVE DAC - it's nothing special in its stock version. I would never buy one to use it in its stock version. I have a DIY tube DAC with multiple AD1865NK DAC chips and a JLSounds USB/reclocker that I prefer over the stock DAVE DAC. But the DAVE is really a "platform" that with some work can become as good (or better) as any DAC, regardless of the price. There are 3 things that I've done on my DAVE DAC to bring it to that level:
  8. I might be stating the obvious here, but keep in mind that the DAVE sounds very different via USB and vis AES or SPDIF. In my system, I get different sound when I get my server's USB output connected to the DAVE's USB input and when I connect my server's USB output to the SRC•DX USB to DX Bridge and then to the DAVE's dual SPDIF input. I much prefer the SRC•DX, which makes me think that the DAVE's USB input is not very good. It's just another variable to consider when comparing servers and using different inputs on the DAVE.
  9. The Taiko chassis will remain the same large size. We can figure out how things fit inside later. The idea is to have an all purpose / no compromise chassis for DIY experiments (or to be able to build a dual CPU Asus SAGE server). I would like to have the unregulated power supply right next to the Taiko ATX with very short cables in my build. The only downside of that is having a transformer in the same chassis as the motherboard. That was always audible in my past experiments. But according to Emile there are ways to take care of that, and that's something I will be consulting with him
  10. The Taiko ATX excels in high current draw applications, which probably makes it a good option for GPUs. However, I don't have any first hand experience with that. If I was to guess, powering the GPU with one Taiko ATX and the computer with another might be a good option. Please report back if you try it.
  11. Then you will run in the same situation as @StreamFidelity where the 12V Keces P8 and the 12V output from the HDPlex (Taiko ATX in StreamFidelity's case) would be connected in parallel to the 12V rail and would be fighting to supply current to the 12V rail. The results would be unpredictable. It's not impossible that the unpredictable result might sound better, but the chance is small, and it's not something I would do in my system. You know my recommendation - sell the two Keces and HDPlex, build an unregulated LPS and get a Taiko ATX :). Your motherboard has one 8-pin EPS
  12. Motherboards typically have only one 12V EPS rail. Even if there are multiple EPS connectors, they feed the same rail. Those Molex pins are rated at 5A. So an 8-pin connector can provide 20A (or 240W). For obvious reasons some motherboards may need more than 20A. And the solution for that is to add more EPS connectors. An 8-pin + 4-pin connectors would give you 30A (360W) theoretical limit. An 8-pin + 8-pin would give you 40A (480W). The dual CPU ASUS Sage motherboard has two 8-pin connectors and one 6-pin connector which can supply 55A (660W). What happens when you connect the 4-p
  13. The biggest strength of the Taiko ATX is to power the CPU, especially with power hungry CPUs. If your 12V EPS rail is consuming let's say less than 3A, and you have a high quality LPS, keep it. It would probably sound better than the Taiko ATX. Also, if you have a 3-rail good quality LPS (3.3V, 5V, 12V) to power the ATX connector, it would probably sound better. However, if the CPU is drawing more current (my dual CPUs consume 7A), this is where the Taiko ATX really shines. But you can't just feed the Taiko ATX with any energizer. The Taiko ATX is as transparent as it
  14. My guess is that the USB card (combined with TAS and Taiko's USB driver) would keep the Extreme on the top for some time, until Taiko comes up with some newer technology, at which point they can make the USB card available for DIY. There is major global parts and supply shortage at the moment. That might be another reason. Keep however many USB card can be produced for current and future Extreme users? I think we would be able to buy it at some point in the future. But probably not anytime soon...
  15. I had the Taiko USB card for a month in my system. A Taiko Extreme user loaned it to me. It went through a pretty bad burn-in slope (connected directly to the DAVE DAC). After the first 7-10 days it settled and became really good. Unfortunately, I could not power it up with my Sean Jacobs DC4 LPS. It required 2 rails (5V and 12V), but also takes power from the PCIe slot. According to Emile, the 5V and the 12V rails need to come up at exactly the same time as the PCIe power. Given that the card was not mine, I did not want to risk damaging it and did not try powering by my DC4.
