Without a shim my vertical tonearm adjustment is bottomed out. I need a shim to raise the arm to get that little bit of adjustment. I cannot lower the tonearm enough without it. I hope it works. I just need a tiny bit more adjustment. The shim will raise the arm 3mm.

Iām sure you know this, but WAM Engrg. (Wally Tools) has resin and brass shims of various thicknesses, just in case this one isnāt ideal.

What I like about the one I chose is it is carbon fiber. Less weight. I would prefer zero weight.

Makes sense.
In case you donāt know, do not file or sand carbon fiber without a suitable mask.

Initial feelings on the DS Phono II are positive. Is it better than my XP-17? The Magic 8-Ball says āOutlook goodā.

Well, that speaker placement didnāt last.
Speakers are now further apart again and back on the floor mats, but am using the PS Audio feet that came with the FR20ās. There is definitely increased bass with the feet versus without.

I hope you donāt mind a suggestion (and I hope this was not suggested before):
If you have not done so already, try the speakers with little and no toe-in. The design materials used for the mid-frequency and high-frequency drivers leads me to expect they will image very well and have an expansive sound stage with less toe-in.
If you lose any sense of center stage or upper frequency coherence with the greatly reduce or eliminated toe-in, then try gradually moving the speakers closer together until those two performance parameters lock in for you.
My experience suggests you may not be getting the most you can from your speakers.
Of course, what sounds good to you is all that matters and I donāt mean to āintrudeā.
Cheers.

With the speakers closer together, there is too much mid-upper bass (room nodes start to affect things). Every time I think Iāll try putting them closer together, the mid-upper bass becomes too much. It took me years to finally get the correct speaker position for the Sonist speakers in this same room. But figured I would try again now that I have better electronics behind the speakers. The result was that the soundstage collapsed and too much mid-upper bass. Now, with the speakers apart again, the soundstage opened up again, and I mean really opened up, and there is minimal room interaction affecting the bass. There is also a good center image with the speakers far apart and with a decent amount of toe-in. The tonal balance is now just how I like it.
No intrusion felt. I like to hear suggestions.

Your room, your ears, your music and your listening bias. All good.
Having heard it myself I think you may be chasing your tail with further speaker position adjustments.

Zero mass and infinite rigidity. The holy grail.

So hereās my initial assessment of the SDFB and graphene sluggo in line to my P20.
Iāll cut to the chase. First, both the regular pigtail and a try to upgrade (using a Furutech cord) were unsuitable on one side, when the other side has Audioquest Dragon going to the P20. My opinion based on my own experience is that the cords on both sides of the SDFB need to be as good as they can be, otherwiseā¦ well, an audiophile is just wasting their time. The nearest unused high quality cord I had on hand is my TWL Obsession (not a bad cord for the money - sorry Al, no Dream 2020 just yet!), so in it went. My wife and I listened to a bunch of music, and then I went back to the M2 fuse with the Dragon going straight into the wall. I must be an odd duck, but honestly the differences are those of āwhich one do we like betterā. There was no clear knockout punch from either configuration.
This is my thought - and itās my own opinion about my system so it doesnāt apply to anyone else. 
For my system that Iāve spent a considerable time fine tuning to the best of my ability, introducing a rather small change like this simply brings a difference, and not necessarily a decided improvement. Everyone elseās MMV. Iāll continue to listen of course. I may decide I like this difference.

Your honesty is appreciated, and your summary is likely what we all hear and attribute to improvement vice difference.

Tony, give it a little time. I found the Graphene Sluggo in particular to take hours to really settle in.
Like you I found power cords to make a profound difference betore and after the SDFBāI use the same before and after in my system.

I do plan to give it more time, yes, though the SDFB and graphene have been in the system for almost three weeks at this point.

What did you think of the copper Sluggo?
All our systems are different as are our perceptions and assessments. In my system the SDFBs are far from a āsmall changeā as far as their improvement in the system.
