A lot of people has been talking about Mogami 2549 and no one is talking about Klotz MC500 that i think is better.

For what it's worth, I am using Grimm TPR for AES conections, only four feet long, but works a treat.

Do you mean Klotz MC5000? I don't see a 500.

The MC5000 is double spiral shield in opposite direction as opposed to 2549's single spiral shield. Gotham GAC-2 AES is also double spiral shield like MC5000.

I'm not sure how they vary in twists. 2549 and GAC-2 seem to use additional tube(?) to maintain the structure, while MC5000 looks like a kind of rubber inner jacket thing for maintaining the twist. I'm not sure which approach among these is the best (TPR included) for symmetry, shielding that covers as much as possible but doesn't add anything to the signal. No drain wire on either.

BTW What else have you compared with the MC500/5000? Your feedback would be appreciated.

Only minor issue I have with the TPR is that they are very stiff, so like if I use them in the rack patch on the desk they stick out rather high in a bigger arch then the usual softer cables! No biggie, but sometimes a little bit anoying.

They sound a bit sharp but very clean and clear, without being able to prove it! Just feelings. :P I think the slight sharpness feeling is just because my system sounds so good now I have a tendency to play a little to loud now and then, and get a litte ear ringing from that the day after, like today.

It sound tremendously good here now, and the full chain is all quality stuff, so the TRP was the last piece of the pussle.. For now!

Very happy with them.

Gonna try power cleaning and power cables some day, but thats for another thread. Streaky swear by it and others I belive in too so I gotta try it.

Re reading this whole thread, I might be curious to try the Van den Hul to feed the monitors. It would not hurt to tame the sharp TRP highs a tiny bit, as im very sensitive to those frequencies. I will give it a go next time.

One queation though: everything else being TRP, will it be sufficiant with Van den Hul for only the very last step, to the amps? Or would I need to change from converter to monitor controller also, for it to make its “effekt”. My analog rack is all patched up with TRP also, and used for tracking and 2bus processing, but not for mixing.

For the past few weeks I did some more comparison with the 2549 and 3173 in the other rig. I've since removed the 2549 and gotten used to the 3173. It's just so damn crisp and extended. The 2549 is veiled in comparison. It sometimes does feel irritating on days where I'm fatigued, while the 2549 will never feel irritating. However, on most days the 3173 is just so detailed and locked in and more alive than 2549. Dialog in movies and vocals is full bodied with 3173 and very clear.

I still can't believe there would be this much difference between these cables at max length of 15 feet. I don't know if it's simply capacitance and/or something else like SCIN. Usually people say that capacitance and high frequency roll off wouldn't kick in until several meters or feet. I wouldn't think that 15 feet would be that much, but if its simply a matter of capacitance, then I'm shocked that it kicked in that early at 15 feet on the 2549, which is regarded as their best analog cable for high frequency application. I'm really perplexed? People usually make it seem like it's something that happens at hundreds of feet.

Mogami rep also still prefers the 3173 over 2549. We did have a discussion about SCIN as well in 3173 with respect to its construction (spiral braid and the gauge of the drain wire and the overall gauge of the shield, and the resistance of shield to drain wire and how it compares to foil designs.) SCIN shouldn't be a significant problem in theory with the spiral design of the 3173. Still, it's hard to conclude what the actual measurements of the 3173 would be regarding SCIN to 2549 or TPR. If someone could do those tests, that would be very useful. I wonder if the audible difference I'm hearing between 3173 and 2549 is only due to differences in capacitance or if SCIN is also a factor along with some other parameter(s) that I haven't considered yet?

I can fully understand why people might prefer one cable over the other. Although which is the more accurate one is hard to say without a reference or measurements.

In the future I might consider getting a short pair of 3173 to match the TPR to see how it does in the Amphion rig for both analog and digital use.

True, check out this arch!

In this modular synth application it can be useful; prevents "spaghetti" as seen with the droopier Mogami 3080 above, which hang down over the lower row.
