Some nice variations being discussed.

Rob's PoE:
They really do take things up a notch in terms of bass extension and noise removal. I am letting them bed in before I write more.

Hi Rob

My Dual cat 8 port arrived and over the weekend I tried it out with U green 1.5metre cables on the - and + which I had spare. Amazing impact already!

I am using them to power a little SD card player I’ve been playing around with which is an incredible find.

My wife exclaimed what happened to the bass! Also the sound is cleaner and more dynamic. How can this be. What a great find - many thanks.

Now I’m going to order some AQ forests.

Cheers P

I couldn't afford individual Cinnamon cables so bought an 8 metre Cinn, cable, cut off the two plugs and then cut it into 6 pcs @ around 1.3m each to make up 3 PoE cables with Cinn. cables on the v+ and v-.
Stripped and twisted the wires together at the ends (for each cable) and soldered these to my plugs.

At one end I have two Cinn. cables going into a large jaeger plug that fits directly into my power supply (easy) and the other ends are soldered to a dc plug (not so easy :) ). For the dc plug, I had to leave a couple of inches of the quad canare cable already attached to the plug and solder the Cinn cables to the quad wires.
A lot more work that Rob's design but didn't have a choice as I wanted to use the Cinn. cables and funds were short. I don't have the option for cable swapping but this doesn't worry me as the SQ is superb; considerably better than the single Ugreen PoE I was using before.
I'll try these for a while and then fit some ferrites to see if these make a difference.

Good to see you like the SQ improvements. I'm finding as I simplify my USB chain - that many of these other USB enhancement gizmo's are really not needed now with the PoE DC in the power chain. It now appears to me that the DC power leg is the most critical part of top USB source chain.

Just a F-1 and a decent split USB cable and PoE DC.3.1 is really all one needs to get really excellent results. I do like the iPur2 and look forward to trying the iPur3, other then that not much else needed for truly extraordinary SQ.

Cheers

I have been using my dual PoE for the last couple of weeks.

Using the AQ 1.5m Pearl x2 in place of the Ibra was a nice step up. Using the AQ Pearl for + and - lead to a WOW ......but, although the bass was AMAZING, and a wealth of detail was revealed, I found that along side this came a level of subtle noise that effected the vocals.

I added two ferrites per AQ, but this returned me to more or less where I was with AQ x2, but slightly less relaxed.

I started swapping cables, including AQ x 2 +ve with Ibra x2 OR 3m flat Ugreen on -ve. This was on a par with the 2 x AQ, with a bit more detail but a tad less relaxed.

Finally I returned to using the AQ Pearl for + and -, but used a ferrite on the exit of each AQ. This gives me the best sound I have had from my system. The WOW of no ferrites isn't quiet as great, but the relaxation is fully there allied to better bass and detail.

A few weeks I tried a Cut Loose cable in my system as a spdif. This cable costs £1,600, and clearly improved the bass and top end. This PoE step is every bit as good, for a FRACTION of the cost.

I didn't find this a simple and straightforward step, so if you try it then ring some changes - well worth the time and effort.

Excellent, thx Bob,

M

Rob, are you still using your USB HUB?
I'm still looking for one HUB that can be connected with USB adapter to Icron and which use 5V external power.
