And why would an $800 pair of BAV cables be better than 1800F for a subwoofer crossed over in the 30 hz range?
The cable isn’t for the sub.
I have a 32’ set of BAV XLR’s running my D&D 8c’s and the work perfectly.
did you have the opportunity to try any other copper?
Not this time but I had in the past with a shorter set. These cables needed the flexibility that the BAV offers as the I needed to run them under the floor and the D&D 8c’s are set close to the wall (<20cm). I think for the very long length the BAV offers some design traits that are more desirable than the other Iconoclast series. You should be able to search this thread for info.The BAV is also a very high quality built cable FYI.
The Iconoclast TPC XLR’s were slightly better in my other system but they only needed to be 3 or 4 feet long and I could live with the cable stiffness.

I’m working on it but time is running short.
The BAV cable design was based on Iconoclast using more affordable materials. It does include a better OF copper than the TPC copper used in 1800F. This is an affordable solution to long runs where the budget prohibits Iconoclast. A further step up is the Gen I Iconoclast cable in TPC. BAV cables are also a great choice for home theater applications.
I went from 1800F to TPC 4x4 and then to BAV. I needed the flexibility for my thru wall install. 1800F does not compare well to BAV. To rank them in my system, if 1800F is a 1, BAV is 7 or 8 and TPC 10.
This is for full range signal, not for a sub. I don’t think I could hear any cable differences for sub frequencies line-level into class-D amp in sub. I run speaker-level into Jensen transformer to single-ended to sub.
Full-range 1800F is dull and lifeless and lacking coherency compared to BAV and TPC 4x4.

Let me know what you work out, and I’ll make a point of stopping by.
Lower total cap on long BAV cables makes the driver circuit’s life easier and more linear. Don’t need the complex 4x4 or 1x4 design at low frequencies so spot on there. Current is diffusion coupled through the wire at sub frequencies.
The BAV are TPC copper to keep the leads most affordable. Bob misquoted the signal copper…sorry about that. People use these specifically in longer lengths that add-up in price and we didn’t want to exclude the products end-user reach using too $$$ copper.

Sorry Brodric for not being more specific - Yes, these are speaker cables not ICs.
Yeah, it might now be the case that being outside the USA precludes the trial offer from BJC/Iconoclasts = a bummer for sure.
The opinions of others on Iconoclast copper comparisons of ICs are here and hopefully forthcoming for you yet.
But for a full range signal is the 4x4 or 1x4 design a better choice (if bend radius wasn’t of concern)? I haven’t decided whether to split my electronics into a digital set and analog set, or keep them all together. Either way I’ll need a full range 30’ cable, but I don’t know how much bend radius I have to play with at one end of the cable. At the other end of the cable bend radius won’t be an issue.
If I split into two separate stacks, does anybody know if a fiber optic HDMI cable like the Ruipro can be used in an I2S application? @tedsmith could a Ruipro be used to connect a DMP to a DSD (for example) without sacrificing jitter?
Very probably, it has a much higher bandwidth than the other hardware in the circuit and it should be terminated correctly if it is HDMI certified, so I don’t think it will inject any significant jitter. It could inject noise if it uses non-linear regulators to covert the HDMI 5V to some other voltage.
I don’t know if the HDMI spec allows ground isolation or not, I suspect that only the signal connections are optically encoded, but I don’t know for sure. Still the Corning 3.Optical USB cable has copper for the power and ground and fiber for the signals and it makes a positive difference for most.
Is the signal transmission protocol of any concern? For example, some manufacturers use the HDMI connector but have their own proprietary protocol for the link (eg Esoteric ES-LINK or MSB Pro-ISL to carry SACD). Can the HDMI fiber optic cable carry these propriety signals?
The cable should be a cable, what goes in has to come out. Active USB extension cables need to know the USB protocol because the segments are connected by mini hubs, but this kind of thing isn’t an issue for any sane length HDMI cable.
The I2S data signals are almost certainly correct for the DS and DS/DMP, etc.
If some of the other connections (the two I2C wires (SDA and SCL)) aren’t hooked up (which I seriously doubt) then the handshaking between the PWT/DMP and the DS which allows DSD and also signals preemphasis could cause grief.

I just asked Ruipro that question and they said SDA and SCL are connected.
I have Ruipro hdmi cable for the best video quality for my 4k projector. I never tried it i2s but i can do it. I will connect Matrix to dsd dac and report later how it turns out.

There is no jitter, they call it… “no signal loss, delay, judder”… 
That’s just the video,as what they at Ruipro mean by that. I tried Moshou 8k optical hybrid video cable i2s and it didn’t work,no sound at all. Maybe tomorrow i have time to try Ruipro i2s.
By extension from what @tedsmith said, the RuiPro “should” work because the SDA and SCL pins are connected between I/O. Wait for the verdict of your test to confirm.
