    You still have the sound of an amplified stylus being dragged down a 1500 foot canyon of plastic.

    Tonearm geometry doesn't enter into it.

    Then you disagree with the article then?

    The Audiophile Thread

    The article is saying that by spacing the tracks, based on the distance from center, and accounting for the tangential angle, one can cut a larger signal in the vinyl. If that's the case, then the signal to noise is higher, no matter how the noise is generated.

    So was your last statement about a stylus in a 1500 ft canyon of plastic. I'm not sure what is worse. The audiophiles or the anti-audiophiles.

    Then you disagree that's how a record plays?

    "The unabated rise in the popularity of records has led to a shortage in production capacity. The HD Vinyl solution promises to eliminate that bottleneck while reducing the overall time and cost of manufacturing records."

    So records made in this manner will be cheaper? Cool. I guess there's nothing to lose, then. It doesn't seem possible that it could make them sound *worse,* right? Unless the "warmth" many attribute to vinyl - which is actually a product of distortion - is eliminated in the process. Then I guess what you'd be left with is a giant wax HDCD that deteriorates a little bit each time it's played. Oh well - bigger artwork.

    "Add the benefit of superior-sound and longer playback time to the mix, and you can see why this is a technology that could pique the interest of audiophiles who are already invested in vinyl playback systems."

    Anything to get these damned vinyl folks to give their money to retailers instead of exchanging it between themselves on Discogs, right?

    Anyway, I wouldn't want to give a yea or nay on this until I actually hear it and compare, but if it's going to make new LPs cheaper and not sound any worse, then I would have to say that it's starting out with the presumption that it will be for the overall good.

    How many people run 2 subwoofers in their system? I've had one for many years now and thought it really added a lot to the music. Better dynamics and more weight to the sound. I recently had the opportunity to pick up a second sub exactly the same as my first. So now I am running stereo subs. I have to say the amount of effortless kick and presence in the presentation has gone up several notches more then before.

    I know, bass that low is not terribly directional, so I doubt that it has anything to do with them, being a stereo pair. It's more of having additional air being moved at those frequencies. No, it's not the same as turning up the first one.

    I have 2 towers, each one has a subwoofer. The real advantage of more subwoofers is that the calibration for bass holds over more of the room. One subwoofer which is, yes omnidirectional, however will have more multi path phase interference, constructive and destructive. Some folks have swapped +/- on one side of a two way full range speaker setup just to get a smoother bass response. The phase reversal doesn't impact higher freq. that much. Newer receivers are X.2, with the .2 meaning independent subwoofer amplifier channels with calibration. The newer Pioneer elite series receivers are .2 and have much lower frequency EQ of gain and phase than they did a few years ago. Additionally they are qualified for 4 ohms, which more serious bass handling.

    While true that low frequencies are more omnidirectional than high, in low frequencies the phase coherence of the combined waveform is MORE important, not less, than HF. Therefore subwoofer placement can be critical to anything other than pipe organ recordings.

    And I do not believe that wiring one of your speakers out of phase is recommended practice.

    Yes, but 2 subwoofers allow more control than placement of one subwoofer. Placement of a subwoofer is restricted by the aesthetics of an environment. I'd argue that even 4 subwoofers, front and back would even be better. More degrees of freedom and control over what arrives at the ear from different directions is key.

    Yes, that's my findings as well. I have more bass now but it is smoother with less boom in the room. The sound coming out of both subs seems to help cancel nodes to some extent. Of course, if you stand in the corners of the room you will still hear that nodal boom, but it works fine for my listening position.

    I went to stereo subwoofers back in the 90's. The test disc was Enya's Watermark. The bass was all distorted until I got the 2nd subwoofer. It seems like she was playing minor 2nd's at the bottom. But yes, I feel there is more presence. I get some skeptical looks from some folk......my subs are the 18" Cerwin Vega drivers with 4' reverse K cabinets. They were used in a Seattle theater for the Sensurround movies of the 70's. Peak at 20Hz. Drive each one with 360watt Jeff Rowland monoblock. Also use Stereo Bryston 3-way crossovers.

    Yep.

    Dr. Earl Geddes pretty much proved that multiple subs (4 seems to be the best) will sound substantially better than one. Even several inferior subs sound better than one very high quality sub.

    He has several interesting papers, and an informative Youtube vid, explaining the hows and the whys.

    OK, on to something new ...

    How many of you cleaned the contacts on your system within the past year?

    I usually do this in the winter months, but I was lax this year. I did it today. Now the system sounds bright and forward, but very transparent. I guess it will take a few days to settle back.

    "Cleaned the contacts"? What, you mean like the RCA cables and speaker spade lugs?

    RCA jacks, cable ends both interconnect and speaker, AC connections ... all points of contact between components.

    Tell me you never did this Robert? If you haven't done this it would explain why do don't seem to hear a lot of differences that many of us hear easily.

    Basic rubbing alcohol and cotton balls, Q-tips, etc. I even grab a pipe cleaner and twist the end around something the size of an RCA pin to make a 1/2" long closed spiral, then I wet it with alcohol and wind it around that RCA pin and scrub out the inside of the barrel. I generally don't like applying anything to the contacts after they are clean, but I do put a little shot of Caig Pro Gold into the female AC outlets before plugging the cleaned male AC plugs back in.

    Basic rubbing alcohol is 70% isopropyl alcohol, with the other 30% being water. Probably not a good idea to be treating your electrical conductors with water there, Bob.

    Have any of your connectors ever appeared to be dirty?

    The alcohol dries quickly leaving them shiny. You don't really see the dirt or oxidation on the connectors, but you sure do see it on the Q tips and cotton balls after cleaning them.

    I'm really surprised at the reactions here. Do mean to tell me you are audiophiles and have never cleaned your connectors? I thought that was one of the basics of the hobby. It's one of those free things you can do that vastly improve your systems sound, right up there with proper speaker placement.

    Make the effort, you will certainly be pleasantly surprised.
