AudioQuest Ethernet Cables

Hi, yes ferrite clamps can be helpful to reduce RF currents.

i found my NAT03 antenna lead is very sensitive to RFI... So once I had elimated the low level warble I knew my troublesome sources of nearby SMPS and data network RFI were elimated.

OK, my ferrite clamps go on everything that's got a wall-wart I even have very big ones that can go over the audio gear power leads. I wonder if Naim gear likes those. I know my old Nordost speaker cables (before I moved on to Naim) did not like the ferrite beads. Even though the top frequencies transmitted by speaker cables are probably waaay below what a ferrite bead can attenuate... So I can't explain it.

ok - I'll try some and report back in a week. 30 days money back guaranty. :-)

I understand the idea that using audiophile ethernet cables in a fully wired application “may” result in better sound.  Would that also be the case in a wireless application when all of the connecting devices (modem, router, and music storage) are located in a office and music is received wirelessly (W4S Sonos) in another room?    

I think if you've got several grand (or tens of grand as it may be) of Naim streaming gear then a couple hundred bucks for some Cinnamon and a switch is well worth it. I noticed a difference on my UQ, though not as big of a change as transcoding FLAC to WAV (really the missing link if everyone isn't doing that already). 

Since both of my switches live in a closet on the floor under the hi-fi alongside the Vortexbox and modem, I used one 3m length from the UQ to the switch, and then a .75 from the VB to the same switch. Since .75 is on sale at B&H in NY, I'm thinking of adding couple more .75 lengths between the switches and the modem to see what happens. 

I have the wall warts from the switches, modem, etc plugged into a wiremold power strip. I was wondering, if anyone knows a good source of 'decent' switched power supplies (if there is such a thing). Obviously the wart for my VB is better than the warts for the switches, though not at all of the level of a linear supply, but that's down the road, and would probably be best for the VB.

Linear power supplies are not that expensive (compared to the rest of our gear), just biggish and heavy, I used to own several when I was into amateur radio... Ham radio gear doesn't like SMPSs

I've seen those. Most have screw terminals - how does one use those? Strip the wire and attach I guess? A lot of the ham ones I've seen are 13.8 v. Does that matter for 12V?

Sorry, this is a whole new world for me. And not really sure just how many of these I could cram into my closet (I think they also get quite warm) though I think some you can run more than one piece off of.

Yes, most ham gear operates at 13.8V, because that allows mobile operation (from a car battery). But better power supplies have adjustable voltage and usually a built-in voltimeter.

Yes, you would simply buy at radio shack a length of cable terminated with a plug that goes into your switch, just like the cable coming out of your wall wart. Be careful with polarity (positive vs. negative leads) and make sure your wall wart is a DC, not an AC power supply (I've seen the later...) Worst case you'll burn a $30 ethernet switch, but you'll learn something useful in the process

So something like this:

Looks like I could solder some banana plugs as well. Might work nicely for the VB as well. 

Or this for the Vortexbox. http://www.dxengineering.com/p...De57wCFdBqfgodZwoALw

Exactly. Will look mega-cool next to your equipment, too. Visitors will think you are building a back-to-the-future time warp generator.

I auditioned AQ Vodka over the weekend with NDS & decided to keep it. Big enough differencies compared to bulk CAT5e/CAT6 cables. Thanks for writing some Chord & AQ cable comments in this forum. I bet that at some point Naim will do own cable as well.

Cinnamon will do for me, between the switch and the Naim boxes. I have Pearl between the router and the switch, which makes a nice improvement. I may well try a Vodka between the switch and the SU one of these days, but the Sarum is way out of my league!

I will try Sarum also, wondering if I should try DIN-XLR first?

Sarum is too expensive for me to contemplate. I don't doubt it's a big step up from Vodka, but at the price, should be.

Can you share which brand and model PSU you got?

I hear you - I hate the fact that my carefully electrically isolated Naim kit is connected by a cable to something powered by a horribly noisy SMPS wall-wart (I mean my router).

Sorry, but in this corner of the woods (Poland) I'm not sure who the well known international supplier of specialist power supplies is - they may not be so well known down here... Any advice appreciated.

It was from a well known international supplier of specialist power supplies

And unless it's from a supplier who's name rhymes with "Fred," there is no prohibition on discussing other companies/suppliers here on the Forum, so long as the linking rules are followed.

Ah... I see  I thought that company only makes power supplies for specific audio components, not the general use ones for something like a switch or a router...

wouldn't using wireless also assist in isolation?

So who is it??????
