Cable science? Indeed! Physics has a lot to say about "the ideal audio cable", particularly about RFI sensitivity and microphonics. RFI immunity hinges on precision control of geometry, perfect symmetry of the cross-section and good shield coverage.
This is the least microphonic cable in the industry by a margin of 20dB.
The Grimm TPM 'Twisted Pair Master' cable uses tape-wound PTFE insulation, silver plated copper wire, glass fibre fillers, no drain wire and two thick layers of braid shield. A bonded semiconductive interface layer under the shield makes this the least microphonic cable in the industry by a margin of 20dB.
TPM provides the most natural and least coloured reproduction available, which makes it a true reference for mastering studios, high-end home systems and mixing rooms alike.
The sound stage renders almost holographic with a very high precision and spaciousness, as if there is no cable at all.

My new studio is wired with TPR

A great new day here with a relaxed and very detailed sound in the monitors and between all analog gear.

I’ve rewired my studio with TPR cable and I now bring some with me to recording sessions as well. It is extraordinary cable.
Noah Scot Snyder, Los Angeles (TPR)
Wow, what a difference...!
Ronald Wanders, hifi enthusiast, Zeewolde (TPM)
A facility is as good as its weakest link and by using TPR the cables are not a weak link anymore.
Ronald Prent, Wisseloord Studios, Hilversum (TPR)
I LOVE the clean transfer of your TPR cable. It´s like there´s no cable at all.
George Tanderø, Mixing & Mastering, Oslo (TPR)
TPR outperforms all the others providing an impressive stereo image and a stunningly accurate phantom center.
Philip Opdebeeck, Little Major Mastering, Antwerp (TPR)
I switch over to Grimm TPR tomorrow. After extensive testing I could not find a better alternative. This cable gets so close to the original it's frightening.
Mark den Hartog, Zownd Mastering, Leiderdorp (TPR)
The combination of Grimm Audio TPR with Neutrik EMC XLR's seems to me to be the non plus ultra at the moment.
Günter Pauler, Stockfish Records, Northeim (TPR)
I love your cable because it is effectively inaudible. With TPR, cable quality is no issue anymore.
Jan Didden, Linear Audio, Turnhout (TPR)
I'm not the 'Ahhh & Ohhh' type of guy when it comes to subtle differences, but the difference this makes is so clear.
