Long XLR's: PAD Venustas versus Mogami

Since when does your hearing deterioration obviate gear differences? Does soundstaging comprehension or perception of tonal subtlety change? No. Note how many pro engineers are over 50...or over 70...mastering geniuses like Bob Ludwig, etc. Some top end goes but that's pretty much it. I can hear gear differences and I've been playing loud guitar since 1967...some tinitus and some top end loss...and ghostly voices inside my head to keep me company.

Al, maybe I had it reversed?

I run 5 meter pair of purist dominus (updated) in XLR and also have mogami. My einstein preamp have very low output imped for tube preamp. The Dominus sounds a lot better than Mogami. Mogami sounds opague with closed in treble and lacked detail. I also compared the Venustas in 2 meter config and they are better than Mogami as well. I was hoping the Mogami would equal the purist so I can save some cash. this was not the case.

I recently have great results with Cardas bulk tonearm cable (shielded). This equal many of themuch more expensive tone arm cable I tried from MSRP 500 to 4000.

I am itching to bulid a 5 meter XLR version of the bulk tonearm cable to serve as interconnect as it seems to have low capacitance. ANyone sees any problems with this concept.

Almarg- Oyaide is an interesting idea. PA 02 only has two connectors. Where does the ground goes in XLR, should I hook the ground to the shield?

What is the specifications in cap, ind, on PA 02?

Thanks

Yes.

BTW, the Cable Company page for the PA-02 that I linked to earlier appears to have the description of a completely different cable, even though the title and photo at the top of the page are correct. Use the information at the Oyaide link I provided.

What is the specifications in cap, ind, on PA 02?

As indicated at the Oyaide site, the capacitance is 32pf/meter, which is very low.

Inductance is not directly indicated, but it can be calculated from the capacitance and the specified "characteristic impedance" of 120 ohms. Using the relation Z = square root(L/C), which is an approximation but an extremely close one in most relevant circumstances, the inductance works out to be 461 nanoHenries/meter, which is a reasonable number.

I'll add, though, that IMO inductance is an unimportant parameter for an analog interconnect. Under ordinary circumstances the impedance it represents at audible and even ultrasonic frequencies will be a completely negligible fraction of the input impedance of the component that is being driven, and therefore it will have no effect on the signal seen by that component.

So capacitance is the main parameter to consider for longer runs (where the lower the better)?
