Please note that production of TPM has been discontinued, it will be replaced with SQM soon.
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.
