Building a DIY Music Server

The idea is to fit the Ubiquiti Edge Router SFP inside - you plug one DC rail to the router and have another DC rail to power up your cable modem or another network device.

I would be interested in this. It would be nice to obtain more space and replace the Keces P3 powering my Edgerouter X SFP and SB 8200 modem. It would be great if the product offered the DIY option of dropping your router in and building the LPS or a complete product. I would probably choose the former for additional savings if possible as I already own the Edgerouter.

 

Speaking of the Edgerouter X SFP, I saw a post some time back, I believe it may have been @seeteeyou who mentioned specific routers which use either the same or similar Broadcom chip to the Buffalo/Melco switches we like. Do you think a SQ boost can be gained by using a "good sounding" router or am I totally out of line in my thinking? :)

 

Edit: I do not intend to insinuate that the Edgerouter X SFP limits sound quality or has any negative impact on what we hear.

That's Juniper SRX300 with the same BCM53343 (Broadcom Hurricane 2 SoC)

Last year used ones were like about 100 bucks each but now it's much more than that

Last week there were ~30 auctioned, and another ~30 this week. They all start at $95 and end between $120-140.

 

Though Buffalo did make their own wired router (with a different SoC?)

At the end of the day we just want something with relatively low power consumption while all on-board regulators could be replaced easily, stuff like RPi could be an interesting option

Finally the kernel should be patched in order to improve the latency, and then the kernel frequency could also be changed accordingly

Buffalo bs gs 2016 . There are many report of the sq impact of using pf ultra ocxo clock on this switch .

Did anyone tried the same modification with their less expensive ocxo clock ?

I have used Connor winfield ocxo with great result...just note that the buffalo only works with LVCMOS output clocks....CMOS output does not work

Following up on some earlier posts about building with a Z490, I've not been able to get one up and running.  With 3 different mobos -- ASUS ROG Strix Z490-G, -E, and MSI MPG Z490M -- all will not boot into what appears to be a successful install of Ubuntu 20.04 LTS Desktop (which I use to test out builds).  It just keeps looping around to the GRUB menu and displaying Q-CODE F6.  If I use "Try Ubuntu" it seems to work fine.  Since the RAM is the only common denominator with the above machines, I think it's worth changing this out.  I was using Apacer 2 x 4GB UNB DDR4 2666 CL19 WT from an older build.  Can anyone recommend some RAM that worked on a Z490 build?  Thanks.

@Darryl R it could be you need more juice -See PM

 

The thought had crossed my mind.  I'm temporarily using a Streacom 150W SMPS.  And for all the boards I was using the i7-10700.  It's very close for the ATX, but should be enough for the microATXs.

When commenting on your SGM you mentioned you are using it with HQP and naa. Is that a naa within the Extreme itself (2nd cpu) or an external naa?

 

Yes, on the same machine. The idea came up as a way to exploit both CPUs, since HQPlayer 4 Desktop seems to not recognize the 2nd CPU. So we're running HQPlayer on one CPU (logical CPUs 0-19), and NAA on the other CPU (logical CPUs 20-39), using Process Lasso to assign CPUs. This boosts SQ noticeably, but may only apply to machines like the Extreme.

This boosts SQ noticeably compared to what exactly.

 

Roon?

 

TAS?

 

Something else falling further outside the designed implementation?

Let me spell this out for you: 

  • config 1: HQP directly connected to DAC via ASIO driver
  • config 2:
    • NAA alloted to CPU0, connected to DAC via ASIO driver
    • HQP alloted to CPU1, connected to NAA.

Music playback directly via HQPlayer. No Roon, No TAS.

 

Config 2 sounds better than config 1.

I have no idea how to decode this sentence.

Process lasso and everything else is reaching beyond officially recognized, nee designed specifically for at exclusion of all else, programs.  With exclusion of HQP following direct recognition of what Jussi has accomplished.  

 

I was asking how 'roll your own' you are getting with Extreme Server these days.

This sounds interesting. It would be great if you could share some more details of the Connor Winfield clock you've used.

After a brief chat with Soul Analogue, he confirmed that the following clocks should work with the Buffalo Switches:

 

 

I would not know where to begin so I will do some digging and report back when time permits.

 

Brief update on the new Mundorf Silver/Gold "24" pin ATX connector... I have doubled the ground and 5v cables and the system feels a bit more smooth/effortless. Not sure how else to describe it.

I think I'll have a try with the OH4510LF. I have a MPaudio module to deliver a nice a 3.3VDC... I guess it could work.

You're welcome, all I did was look up LVCMOS OCXOs @ 25Mhz on Digikey and @Soul Analogue confirmed the results. 

 

@tgb, looking forward to your project with the OH4510LF. Best of luck, and hopefully the results are worthwhile!
