Sorry but yeah, you do need to say that. It’s difficult not to have a “what the heck” reaction to “fuse” along with the words “strapped”. In all the years I’ve been aware of SR fuses, I had never seen anyone strapping them. The manufacturer doesn’t even talk about this particular use case. Looking back to your post and I can’t tell if you actually installed the Purple fuses normally into your CX and EX or whether they “are tie-wrapped to the positive wire after the IEC with the fuse dot facing the wire”. I’m not saying you shouldn’t strap them. I’m just saying that it would have benefited your readers to preface your remarks with an explanation.
I've had several at-length conversations with SR pertaining to this. The higher gauge AC-carrying lead is now influenced by the dot instead of the fuse strand and this is uncharted territory for them as they have to sell the fuse as a fuse. [Perhaps] Keeping with company protocol, they are encouraging me to use the Purple/Gold Carbon Tuning discs as the Purple compound on the disc is the same as on the dot only with higher concentration. The higher concentration may be an issue as I've experimented adding a fuse to each leg of the 240V feed with mixed results and if the disc is radiating like an antennae, it may be also throw off the other pole.
After reading the near 100% positive reviews on the fuses [save for the trolls] and what I at least perceived as mixed reviews on the discs, this is the route I have chosen.
I have a DAC with regenerative power supply where putting a fuse in front of the regenerator [perhaps] isolated the expected effects going to its three isolation transformers to L, R and Digital dedicated power supplies. After a number of experiments, I settled on a strapped fuse after the regenerator to the to two paralleled analog isolation transformers and one to the digital isolation transformer. The directionality on each was easily perceptible.
I used to over simplify changes to the system as percentages as I upgraded up from original DX2 to DX3 to CX/EX to OLADRA CX/EX Hybrid PS.
As the imaging expanded out to 180 degrees I would assign a % improvement. Mark Jenkins asserted that I would hear a 50% improvement upgrading from DX3 to CX/EX and I found his assertion to be in the ballpark. Going from SR Orange to Purple is more of a transformation as the presentation moves into 3D sphere-like holography that I didn't know existed past a 180 degree soundstage. The out-of-phase L + R tracks on the Rives Audio Test CD would play back the sound source at 0 or 180 degrees through the original CX/EX and recorded out-of-phase tracks would appear to the listener's right or left but there was no convincing weight or harmonic believably to the out-of-phaseness of the instruments/voices.
In my experience, the brain marvels at these soundstage expansions but once the brain normalizes them, the original enthrallment fades and it goes back to near 100% analyzing the sound.
Examples are the far-right vocal on My Wife [Who's Next], Bonham's drums between 0 and 35 degrees on Since I've Been Loving You or the guitars at 0 and 180 degrees during the intro of Siberian Khatru [Yes-Close To The Edge].
Additionally, choirs and symphonies are now drawing me in as the SR Purple have increased the resolving power to break apart multiple instruments and the acoustic affect of the venue to hearing around each voice/instrument and separate the reverberations of the hall. This is allowing me to listen through entire albums being completely
drawn in to the sphere-like sound space and the harmonic and spacial realness.
There's just more information coming through.
On a different data point, I went back to a comparison between all-Roon and all-Squeeze and comparatively heard a warm glow from Squeeze and a cold presentation from Roon. The detail was equivalent.
The multiple horns on Beginnings on the 2002 Chicago Transit Authority remaster [not the 2015 remaster] and the opening of Sara Hannigan's Let Me Tell You [which musically, I'm not a fan of and is more of a test recording for me] reveals the level my system resolves two or more combined voice/instrument frequency ranges that have appeared smeared played back on my system.
