I have a couple 7050 strips left, and I will experience it too. Thanks for the tip!
I just checked mine, both Dragon PC and HDMI, plus the Firebird HDMI all have the ânewâ design of the DBS boxes 
.
I have an older Coffee HDMI that has the box on the opposite side. It is serving the OLED 65 TV. I found the AQ Coffee does make improvements in video as well as audio on home theater too.
Interesting observation. My two AQ Dragon cord have DBS box starting from the direction current flows. Most all the other cords like tuning ring opposite of the Dragon.
I have a two-inch-wide ring that has enough length for double wrap on Dragon. So, I will try it first to see how it sounds before I reduce the width or length. This is the last tape I have.
I found a Anticable Ref. 3 PC in my audio treasure box. It has a three-conduit design like AQ. It is a great sounding PC, but it sounds too vivid towards the âbrightâ side. I wrapped it with copper tape plus a 2.5-inch ring, and it tamed the brightness quite a bit. I will try to move the ring to the female side to see if it works better. This PC now replaced my Cullen at my preamp. The wrapper/ring made it sound better than Cullen.
My next improvement may be a Whisper PC or a Dragon source PC for the pre, but as of now I am incredibly happy with the improvements to the system.
The absorber tuning rings clearly can change sound night and day with a quarter to 1/8 inch movement on certain parts of a cable. I tried a wider 2,25 and 2.5 inch on dragon same location and both muffled things. There are certainly optimizations and nuances. It gets a bit maddening. Wrapping an entire cable in two foils is one easy change. Ted Smith was stating that the new Edcor output transformers on DS MkIi use a tin plated coper foil shield. I thought to myself how it aligns with my discovery using AL foil with Cu foil over wrapping pn my cheap power cables. It is crazy things one discovers if you experiment with RF and EMI solution in power transmission.
It provides a lot of fun playing the system too. The only drawback is my wife kept telling me to stop listening to the same songs a hundred times a day!
Yeah I have heard that before when trying to tune cables or evaluate differences. Why are you listening to that same playlist every night?
Only when I compare the effect on changes would I listen back and forth with the same list or discs, and after that the list and discs would not be touched for a long time. 
I tried moving the ring on the Anticable Level 3 PC toward female side, and the ring is better at original male side, like other cables. Anticable does not have DBS box so that may be the reason. I was quite surprised by how good the cable sounded from the ring because it removes a substantial portion of brightness and makes it sound very neutral.
Next, I tried the tuning ring on Dragon. In my system, the piano, violin, and female vocal became a bit cleaner and clearer. The biggest improvement is in the solidity and weight of the presentation. But the improvement is not as drastic as Anticable nor Cullen. The tuning ring and Al/Cu wrappers improve lower priced cables more than the expensive ones, I felt.
I need to keep the ring on Dragon for a longer time to give a better evaluation, but more than likely it is real and not my imagination. My daughter, a total non-audiophile, is back for summer break. She is my ultimate evaluator in terms of audio improvements. Often, she has proved me wrong on so called âimprovementâ.
I have some new NOS tubes in the amps and the entire system sounds quite different and better. So, it is a bit harder for me to evaluate the changes. But after a few hours of listening, the ring at the Dragon towards female end did sound better. Still, the improvement in my system is subtle, in comparison to that of Anticable Level 3 and Cullen.
It is a keeper, and I will have the ring on and wait for my daughterâs judgement from a donât-care-about-any-hi end-audio point of view. I am afraid she will give me a bad time.
I just got back to my system today with the dragon tuning ring trial near female IEC. Yes a lot clearer and more separated highs.
The mixes where the artists have had their voices layered in n harmony. Much more distinctive and individualized tracks. Almost like a separate artists definitely recording space is sensed and their is space between the artist and there identical clone. I am also getting wider soundstage. The tuned dragon is going to be a keeper in my system.
Thanks for giving my madness a spin. Please share your daughterâs observations
Well after ten songs in. Three words. Magic, Pure Magic. If you need to trim your absorber ring do it!
I have been playing The Qobuz. P S audio Forum List 1. Not a bad cut yet. Just open and clear. Soundstage to die for.

I will cut the ring to your spec. and listen to it more later. I was watching Warriorâs excellent game (sorry if you are Mavs fan out there) and had too many drinks to make any clear judgement in anything.

Itâs actually âA manâs got to know his limitationsâ
Which doesnât apply on this forum when discussing tweaks and upgrades!
YesâŠand no.
There are actually two variants of the line in the movie. The one I cited and the one in the clip you dug up.

After trimming the absorber ring to your specifications (1/4â narrower and shorter in my case. Amazing!). Iâm listening to Qobuz new John Willams/Yo Yo Ma âA Gathering with Friendsâ excellent album (is that still called an album in streaming?), and there is better improvement in clarity and separation. Strangely the SQ improvement is more apparent in streaming than playing SACDs. But it is still a small improvement compared to rings on others. If I use Lucaâs point scale, the incremental improvement for Anti/Cullen/Purist would be 1 and the Dragon would be 1/4 of 1. The improvement is more apparent in higher frequencies than lower ones in my system.
With another pair of Iconoclasts green XLRs and a new set of excellent NOS tubes added recently, my system never sounds better and more resolving. But the fact you are hearing a bigger improvement means you are probably hearing less background noise in your system than mine. One strong possibility is the P20 produces a lower noise floor than my P15 with its bigger power supply. This alone may explain our differences in Dragon ring experience since it serves as the link between wall and the generator.
I spent longer time listening to the Dragon ring effect also because I have a new pair of NOS tubes in the amps. There is some doubt in my head whether I am hearing the improvement from tube break-in instead of from the ring. But the more I listened to it the more I felt the Dragon ring was the predominate factor. I will keep it on!
I will spare my daughter this time since my music world collides with hers and 20 minutes is too long a music session for both of us.
