  1. I think you're correct. Check comment 3372 on this page: The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator - Page 338 - diyAudio There's a graph that has 4 oscillator outputs with phase noise at 11.2896 Mhz. It includes a Drixo oscillator with sc-cut xtal for that frequency. It also includes a PIO oscillator but doesn't use its doubler. It's far worse than the Drixos, worse I think than even using a doubler can make up for. It's pretty bad. The interesting thing isn't that though. It includes 2 drixos with outputs at 11.2896, but one is double
  2. I hope no one minds my piggybacking on this thread. Andrea at DIY audio said he will probably have another group buy for his oscillators in July. I previously bought an AIO oscillator board with two doublers and an STS board for the 25 Mhz output for the Buffalo 8016 switch. It used a 6.25 Mhz AT cut xtal quadrulpled to 25 Mhz. That seems to be the most economical bundle Andrea has with for that purpose. I'm interested in doing the same thing for the 10 Mhz clock input for my Etherregen. I will need a 5Mhz AT cut xtal doubled to 10Mhz. If anyone else is interested in doing the same I'd apprec
  3. Thanks. I have an Asus ROG motherboard so I guess that means I don't have to cut it. Great. If not it would mean a lot of fiddling with connecting and disconnecting that ATX 12 volt power while experimenting with different schemes.
  4. One thing I'd like to know, on motherboards that have separate EPS +12 volt and ATX +12 volt connections do you have to disconnect the +12 v connection at the output of the ATX power supply if you want to power the CPU separate from the motherboard? Sorry if that's a newb question. I guess I'm a newb.
  5. I misspoke earlier to Topk when I said that I had an SR7. I looked back at my records and I have the SR7T twin regulated PS. I also have the SR5T double 5 volt rail double regulated version to run my JCAT net card and usb card.
  6. Thanks. I run it whenever the system is running. Sometimes I forget to turn the fan on and things warm up quickly!
  7. I currently have a PH SR-7 with 12 and 19 volt rails to power the motherboard and CPU. I'm pretty sure it can handle the load. I haven't actually installed it yet but I expect it to sound excellent. I still think a voltage regulator is kind of a brute force method and don't like the energy inefficiency of that brute force method on a high load computer. If I could get something that is comparable in sound, preferably even better, that is also very efficient that would be great. I think most of us aren't that conscious of the high carbon footprint that our hobby has.
  8. Hi, I knew it wasn't Nenon that posted that info. I really did appreciate it though. I have a "sleeper" audio system because I have a relatively small home, 1000 sf, and I didn't want the system to dominate my space. I installed a bookshelf spanning a long wall with cabinets with glass fronts below it. The cabinets are 24"deep and house all my system components but the bookshelf above it has a false back that is covered with acoustic fabric. Behind that fabric are 3 bass tube traps which are hidden by the fabric. Also behind the fabric is an insulated flexible duct that has an 80 cfm fan in t
  9. That sounds good. I'm planning on using some advice earlier in this thread where it was said that if you limited the voltage to the CPU to 1.25V (even on peaks) that one could keep the temps down to around 50C. I'm planning on that working and keeping my fingers crossed. The AMD Ryzen 9 3950 draws 105 watts at idle. I'm planning on just squeaking by with the Plex chassis heat sink.
  10. I probably did not express myself well. I wasn't trying to incorporate all the intricacies of how an ATX power supply handled processes in the motherboard because I know very little about that. I mostly don't care either. I just noted Nenon's finding that an approximately 340 VA transformer sounded best powering the Taiko ATX on an Asus Sage dual processor. All I was looking to do was equate that size transformer to a different motherboard using a different processor. I don't even know if Nenon Taiko ATX is powering the processors and the MB or if it's just powering the MB alone.
  11. This is an interesting topic about transformer power. I'm interested in the Taiko ATX power supply. It seems like the minimum requirement for transformer power rating would "not" be what is required for peak dissipation but for steady state power during the playing of music. Capacitance can supply peak loads. But that steady state power can change drastically depending on what voltage outputs of the ATX you are availing yourself of. If you are using it to power all the internal cards it would be significantly different than if you are powering the cards from an independent LPS.
  12. I was just using the quoted comments by Emile. No one is arguing with you. Emile's comments on the improvements he's seen with his own USB board had an implicit meaning. He seemed to be saying that the difference between "excellent" and "superb" sound on an otherwise well engineered usb board had to do with bringing up the quality of the oscillator more than anything else. Are you disagreeing that this was NOT Emile's implicit message?
  13. Reading that comment by Emile in "what's best forum" was interesting. I've tutored myself on oscillators just by reading this thread. The Well Tempered Master Clock - Building a low phase noise/jitter crystal oscillator - diyAudio Andrea, the author of the thread, is quite an expert in low noise oscillators. His design philosophy appears to be coincident with Emile's on how to build a low noise oscillator. He doesn't use oven controlled oscillators. It's a very long thread and will take anybody quite a commitment of time to read. It's worth it though. There's some redu
  14. Good to hear all this. I have an SR-7 coming that has identical rails that will go to the identical destinations as yours. Who would have thought. You are in an interesting position having all this accomplished but not having new clocks installed. Might I make a suggest to you and to anyone else planning on buying upgraded clock. Look at this thread: Anyone need a 25MHz Crystal/Clock to theirs Buffalo switch, NUC`s or? At Andrea Mori`s Groupbuy at Diyaudio. - Networking, Networked Audio, and Streaming - Audiophile Style i found out about it about 4 days ago. The DIY bu
