ZenSati Cables’ high price tag can be attributed to several factors, including:

1. Materials: High-end audio cables often use premium materials like pure copper, silver, or gold, which can significantly increase production costs.
2. Craftsmanship: Handcrafted or bespoke cables might require skilled labor, contributing to the overall expense.
3. Design and engineering: Advanced cable designs, shielding, and insulation can also drive up costs.
4. Brand reputation: Luxury brands often command high prices due to their reputation for quality and exclusivity.
5. Marketing and target audience: High-end audio equipment is often marketed to audiophiles who prioritize sound quality and are willing to pay a premium for it.

These factors combined can result in a hefty price tag, like the $500,000 mentioned. However, it’s worth noting that the perceived value of such cables is often subjective and dependent on individual audiophile preferences.

I started my amplifier design work thinking of Total Harmonic Distortion (“THD”). Felt very happy getting that down to 0.02%!

Then I found that odd harmonics sounded harsh and nasty, while even order ditto sometimes even added a layer of “pleasantness.”

Then Intermodulation Distortion! Ugh, nasty, fix that!

Then power amp design. Class A is hard to do if you need a lot of power needed for certain speaker designs.

So, Class B next? Ugh, Crossover Distortion, blech.

OK on to Class AB (Class A up to a limit, then “Class B for the rest”).
What limit?…

And more…

Tomi Engdahl I totally agree. If the signal cables are shielded, I can’t see any advantages with special power cables at all. And I have seen the prices on some of those cables…

Walter Franken exactly. Then the speaker manufacturers uses bell wire from the terminals to the drivers. It’s the audio equivalent of Steven seagal……… bullshido!!

Walter – If nothing else, inside those big, expensive black boxes are PC board traces, usually. Or, thin wire in an output transformer. Heroics in the last 3 meters is a bit silly.

Are these cables safe? I mean, there are standards power cables have to comply to. Are they rated for the mains voltage? What about the earth connection?….

do any of these companies ever show sample level analyses of what happens to a test signal with / without the emporers clothes on? thats the wild thing about this stuff – we have complete information

i suppose the retort is ‘hahaha you’ve just outed yourself as an amateur by even suggesting polluting my signal chain with an AD converter’

Tomi Engdahl …starting with standards compliance! Your insurers will forsake you.

Tomi Engdahl I’ve built a lot of walls of many different kinds. Concrete, gypsum and various types of wood materials, both industrial and private buildings, and I have never seen any other kind than non-metallic sheathed cables with different gauges inside pvc tubes. I can’t see any reason to plug any cables better or thicker than those inside the walls into the socket for the last few feet, because a chain is never stronger than the weakest part.

Signal Ground: Serving as the fundamental reference point for audio signals, the signal ground plays an indispensable role in the fidelity of sound reproduction. By maintaining a consistent baseline, it ensures that audio signals are transmitted clearly, devoid of unwanted noise or interference. This clarity of transmission is pivotal for delivering high-quality, noise-free sound to listeners.

Star Ground & Spar Ground: These terms refer to specific and carefully designed grounding techniques employed within the amplifier circuit. The star ground method involves creating a single, centralized ground point, which minimizes the potential for loop interference and noise pollution. On the other hand, the spar ground method—involving a distributed grounding scheme—equally aims to reduce noise by strategically placing multiple grounding points. Both techniques are meticulously implemented with the objective of minimizing noise and interference, thus optimizing the audio quality and performance of the amplifier.

Power Amplifier Board: Often described as the heart of an amplifier system, this central component is where audio signals are boosted to the necessary levels for driving speakers or other output devices. Proper grounding of the power amplifier board is paramount to ensuring stable operation. Without effective grounding, the amplified signals could become distorted, leading to undesirable audio performance. Consequently, meticulous attention to grounding is essential for maintaining the integrity and quality of the amplification process.
