    Re: A Question

    If you measure one violin, one player & one venue, then come back the next day and do the same measurements, the results will be different. There is little repeatability in acoustic measurements of...

    Re: Why do high-end cables cost so much?

    Blue Jeans Cable already has. Especially for RCA analog interconnects.

    Why do high-end cables cost so much?
    Because to many audiophiles:
    high cost = high-end.

    But in fact the best cables are made by the major bulk cable manufactures like Belden...

    Re: Coat Hanger Cables

    If real differences are heard in speaker cables, the difference is often caused by contact resistance in the connectors. In some recent amplifier power tests, unexpected power differences were traced...

    Re: Audiophile Wall Outlets

    Do NOT 'cyro' an AC receptacle or breaker! It will void the 'UL' listing and may damage the unit.

    Re: Phono Stage With XLR Output

    The Audio Engineering Society 'AES48' standard is about how the cable shield is connected at both chassis ends. It's better known as the 'Pin 1 Problem'. It's true that some audiophile products...

    Re: Measuring AC Power Line Noise

    Yes it can, but only if you have the technical knowledge to use equipment like this on an AC power line. In the R&D lab we would hide the good O-scope probes from the techs. They often made hook-up...

    Yes, Ham radio operators often complain about noise & interference generated by solar power systems in their neighborhood. It's the inverter converting the solar DC to 60Hz AC that generates the...
  11. Re: How important are power cables for linear power supplies ?

    Differences in audiophile power cords are way over rated!
    The cord is only a small percentage of the entire series circuit that extends to that big power company transformer down the street.

    Lot's of new marketing department copy, that's about all.
    Why would someone thing that changing a few links in a long chain could make the chain stronger?

    Re: EP-2750 impressions

    Nope, you want as low an impedance at all frequencies as possible!

    I was just reading a small part of the 500 page Motorola paper on cell-phone tower and building AC power & grounding. They wrote...

    It's just an engineering fact. That's how a series filter works.

    Re: EP-2750 impressions

    It's the exact opposite of what you want!
    You need a low impedance path at all frequencies.
    A series filter is a high impedance path at the filtered frequencies.

    Re: Tube, Solid State, Other?

    For an accurate, Hi-Fidelity, low maintenance sound, it's solid-state all the way!
    For a pleasant, euphonic sound, tubes are the first choice.

    Yes, Safety Ground length from hi-fi component is one of the first priority's.
    Most US hi-fi set-ups only need one 20Amp circuit (but there are exceptions).
    For a big home theater set-up, I would...

    and don't ground RCA chassis connectors that have plastic insulator rings.
    and don't ground a double insulated chassis. It would have a square within a square safety symbol.

    He writes about correcting voltage at a point. But voltage doesn't exist at at point. It's the difference in potential between two points.

    Re: Nordost QKore grounding unit

    So I quickly scanned a Nordost QRT page and it had a ton of alternate universe stuff.
    They start with a few sentences of engineering text then take it out of context and mis-apply it.
