I understood that ifi Audio initially recommended it go just ahead of the DAC but then found it sounded better still ahead of the USB power if you are using one. So you can use it just before the DAC and it will provide an improvement. I don't know about the Wyrd but quite a few folks are combining the iP2 with the Audioquest Jitterbug and find they work well in combination (including me).

it is recommended to put the iP2 infront of the iUSB but i dont use of them, so i could stick it before the wyrd? 

is gonna benifit though im unsure, 2 devices doing the same thing = twice as good? worse then using only 1. i dont want some weird conflicting problems.

The iUSB has cleaner power than the iPurifier2, so they recommend it go between the iPurifier2 and DAC. If the Wyrd has cleaner power, too, the same would apply.

Note, they recommend the iPurifier2 go into the DAC directly if it's not USB-powered (no handshake even).

Hi,
 
Correct, the iUSB (original) and iUSB3.0 both (among other things) generate their own clean power. So place this last in the chain.
 
This is why some people with the Gemini cable place the audio at the PC and power at the iUSB. It never touches the PC power.
 
Cheers.

Hey. I'm a bit confused by this arrangement. So what exactly is connected to what? (And via what?)
 
So an iUSB (or 3.0) would be placed very close to a PC, which would be connected to a DAC via a Gemini cable (with the audio end plugged into the PC, the power end plugged into the iUSB - but with no other source other than an iPower/Power Supply entering the iUSB)?

For the iUSB3.0 - the titles are self-explanatory.
 

Level 1: Clean HDD Power

 
 

Level 2: Compare two DACs (simultaneously, on the fly)

Note:
The left (red) shows this setup can go to two inputs on an amplifier.
The right (blue) shows this setup can go to two identical headphone amplifiers/headphones.
 
The benefit is for direct, head to head comparisons, eliminating the USB cable, the computer, the software - just straight DAC vs DAC. Reviewers LOVE the iUSB3.0 for this as it gives a super-quiet background for two DACs.
 
Last but not least, don't forget to level-match of course as some DACs have higher output levels.

For existing iUSB customers: (Levels 1 and 2 do not involve using the iPurifier2)
 

Level 3: Add the iPurifier2* to the original iUSB

*before or after depending if your DAC is usb or internally powered-respectively)

Hi,
 
Simple notes on arranging iP2 in system:
 
1.) iP2 on its own - always place iP2 at the DAC/USB Device input socket
 
2) iP2 with original iUSB Power - depends....
 
2.1). DAC uses USB Power only for Handshake (e.g. iFI Retro, DP-777), place iP2 at the DAC USB socket AFTER iUSB Power
2.2) DAC powered by USB (e.g. iDAC 2, iDSD in USB Power Mode), place iP2 at the input socket to the iUSB Power
 
3) iP2 with iUSB 3.0 - iP2 is redundant, but can be used at the USB Input of a USB 2.0 DAC, iP2 not likely to improve anything 
 
4) iP2 with other manufacturers' USB gadgets - always place iP2 at the DAC/USB Device input socket, unless the other gadget is felt to give superior results after iP2
 
5) Two iP2s - the second iP2 is redundant, but if it is desired to use longer cables placing the second iP2 between a USB Cable and USB extension can make sure signal transmission works well (as it is an Active Repeater). 
 
If using multiple iP2 in series (up to 3pcs) with standard USB2 ports and USB Bus powered DACs it may be best to place an iUSB Power or iUSB 3.0 in the final position, both to provide clean and sufficient power and to break earth loops.
 
Cheers.

This is my current setup. I must say that after adding the IP2 the level of transparency increased significantly.

I've added an iUSB to my system. I tried connecting to prevent the power from being drawn from the PC, however I couldn't get ISOGround to activate. So I had to resort to plugging in the audio & power from the PC to the back of the iUSB. It has reduced the nasty noises and buzzing from the PC by about 75% - 80%. Hasn't killed it, but I can almost live with it.
 
Would you know if there's a way to get ISOGround to activate without feeding it a power/audio USB signal?

Hi,
 
To answer your questions:
 
> I tried connecting to prevent the power from being drawn from the PC
Just connect the iUSB/iUSB3.0 in the signal chain. Then your DAC will draw a new clean power supply from the iUSB/iUSB3.0 and not your PC.
 
> However I couldn't get ISOGround to activate
In this case the LED's will not light up, however IsoGround is hardware based and will still work. 
 
However other functions in the iUSB also require the USB power from the PC to be present. There is no point breaking the power (and ground) connection from the PC, as this is done internally in the iUSB (and electrically speaking, safely we might add) to guarantee all functionality.
 
Cheers.

How are you configuring them. Which device is plugged into which? Are they stacked at the DAC and if so in which order?
