    Capacitance ?

    Blue Jeans Cables makes a low capacitance coax: http://www.bluejeanscable.co.uk/store/audio/index.htm
  2. When it hits necessity goods then I’ll start worrying. But I find it more likely that we’ll be seeing our taxes raised.
  3. I’m afraid your prejudice could be keeping you from using the most effective transmission interfaces.
  4. If you mean the Innuos switch then no, not from a buyer’s perspective. But that is true of many over-engineered luxury goods.
  5. There’s logic to what they say, which is why I suggested the 100mbps SF110D-05, or why I use a low processing-power buffer/endpoint between my laptop and the DAC.
  6. It looks like it has already here in the WAM. Personally I’d rather get the 1000mbps SG110D-05 or the 100mbps SF110D-05 instead. Or the Linksys LGS105.
  7. I would ignore those comments about “video” cables, they’re nonsense.
  8. It is a bit ridiculous but they wouldn’t be doing it unless there was a market for it.
  9. The two main issues in my view are noise and jitter, since none of the available options is likely to lose any data. Daniel Weiss of Weiss Engineering is still a strong proponent of FireWire: For computer playback, what are the advantages of a Firewire connection over USB, coaxial and Toslink S/PDIF, and AES/EBU connections? One main difference is that Firewire is a bus structure, while the other protocols mentioned are point to point connections. Firewire has several advantages, like: - Our implementation uses the so called Isochronous mode of the Firewire link, which means that a defined bandwidth is allocated for a given connection via the bus. E.g. if on the same bus a hard disc is connected, it can not happen that the hard disk grabs all the bandwidth and the audio link chokes because of that. The audio link has its bandwidth reserved without any exception. - The Firewire is very easy on the host computer CPU power, as most of the work is done by the Firewire interface in the computer. - Several devices can be connected to a single Firewire bus. This allows building multi-channel systems with two-channel devices. That is why the Minerva has two Firewire connectors, i.e., to allow for daisy chaining devices. - As mentioned above, the Minerva can be master clock to the computer, which makes it easier to maintain excellent jitter performance.
  10. Most DACs use sigma-delta chips which convert PCM to DSD before D/A conversion. It makes all the sense to use an advanced file player/processor to perform this step, just as it makes sense to feed the D/A with the highest admissible rate, something not always possible by the DAC's on-board SRC chip.
  11. What matters in a fancy switch: PhoenixNET — Design is focused on 4 areas: Noise, Clock, Power and Vibration. 01. Minimise Network Switch Noise • Simpler 100mbps network switch chip results in lower operating noise floor compared to Gigabit • Network switch chip with no internal switching regulators. All 3 independent voltages supplied by internal Statement-grade linear power supply with independent ultra-low noise regulation. • Massive individual Network Isolation Transformers to further isolate from noise coming from router or connected devices • Just the right amount of Individually shielded, high quality ethernet ports soldered directly to the board with no ethernet activity lights as blinking leds introduce considerable electrical noise. • EMI absorption at the right places so that interference produced can be captured before influencing other components. 02. Increase Clocking Precision and Stability Using the same 3ppb 25MHz OCXO oscillator as used in the Statement, individually powered by its own linear power supply and connected directly to the network switch chip, avoiding precision losses from using external master clocks. 03. Provide Pristine Power to the Components 2 independent Statement-grade linear power supplies with Mundorf Caps to power individually the OCXO clock and the mainboard, keeping the power path short with less opportunity for EMI contamination. 04. Minimise Vibration on Components Vibration was managed at 3 levels: Anti-Vibration feet tuned to the resonant frequency of the chassis, top cover treatment to convert vibration captured from sound waves into small amounts of heat and sturdy RJ45 ports with silicone connection to the chassis.

    JAS supertweeters?

    The dome on the second photo looks off-center.
  13. A quick search revealed that 24/192 is less than 10 megabits/second and DSD256 is around 24Mbit/s. 100 base-t is more than enough for audio.
  14. It is possible that by using a/any switch you are adding an extra layer of filtering between your broadband connection and your Mac Mini.
