Build a dedicated Audio PC

[tony]

I think I downloaded fidelizer at some point on Frans recommendation but never did anything with it. What is it meant to achieve?

[Fran]

Turns off lots of services temporarily (until next restart).

Couple of levels to try - go for "custom" adn then tick all the boxes and select keep networking.


Gives an improvement akin to totalcommander.


It can be automated for headless, but get used to it first before doing that.

Is TC the lazy way of getting there without ticking boxes?

[Fran]

Nope, you can do both.


Worth trying at least....

ive a arcam rpac that i can get us=30 working.
it does play at us=20 but its terrible
we got us=30 down at kens last week on the ciunas with the i3 build, we didnt try any lower as i was convinced that i the pc wouldnt go lower i never even considered a change in dac would make a difference.

I installed a TP-Link TG-3269 Gigabit PCI adapter (from Amazon around 5 STG) into the old P4 streamer and over an ethernet connection I was able to play all formats 16/44 to 24/192. I was able to get around US=150. I then swapped the PC's around because the latency on the P4 was more stable and slightly better than the AudioPC. Over ethernet connection I can get US=125 and this doesn't change over freq 44.1 to 192 but does require a buffer size of 4 samples for the higher freq's.
I'm going to try the TP-Link Model TG-3468 Gigabit PCiE Ethernet card Frizzup mentioned because that will also enable me to use a crossover cable and see what that brings.

TP-Link TG-3269 is realtek 8169 chipset

TP-Link Model TG-3468 Gigabit PCiE Ethernet card has the Realtek RTL 8168 , same as the built in one in the i3 build i7 streacom build

i dont know how important the chipset and its driver is but I've two working good with this realtek one 8168, ive an pci card working fine, and this http://store.apple.com/ie/product/MC704 ... et-adapter which is able for us=45
i know frizzup notified us that the Atheros chipset was non compatible, which is great information so we can avoid it, it will solve your assigning ip address issue, but a pcie card may not solve all issues.
you could chance it:

Hi Nige, I'm in Dub tomorrow so I'll check price in Maplins or Peats and if it's not too far out I'll get one otherwise I'll get from Amazon. I wouldn't buy two pints so it's not so dear. I don't think it will make a Zuma out of the P4 but every little helps.

I had Derek over tonight for a listen to the new zuma build. Not being one to miss an opportunity, I decided to use his ears and mine to do an experiment.

I rigged up a pc power supply (300w smps) to compare to the linear maplin supply.

We played using the linear supply first..... Quick shutdown and swap to the smps, and listen again. It didn't take 2 bars before we both knew the smps was way inferior.

This was not a small difference. The level of loss of detail, warmth, etc was stand out noticeable.

Best factor in a linear supply guys! Pearse, I can rig a lead if you want to try it out with your zuma.

Interesting findings.....
