hospital grade or commercial grade receptacles ?

Now I suppose you're going to tell me that if I got rid of the, ahem, non-audiophile interconnects and speaker cables I could hear the difference when I switched power cables (which I just did a few months ago). Certainly my friend David thought so. If you agree with him I recommend a BS in Physics.

I don't know if you would benefit from a superior power cable or not, regardless of your choice of interconnect and speakers cables.

Your quality standards and system performance are both unknown to me. As already mentioned, you can have all the right names for gear and still not get excellent performance. Manufacturers prove that every January at CES.

If you listened with the dozen or so members of my audio group you would have no choice but to drop the BS about the BS.

Your Physics degree (if you have one) is no more valuable in evolving a sound system than an engineering or business degree would be. In fact, I would trust the member of my group with a Grammy award on his fireplace mantle, a trained classical musician who knows nothing about Physics.

He listened to Purist power cables and invested in them the next day. The source he choose for the audition was one of his master tapes.

Albert, good to have you back posting again. Always lively. And I AGREE WITH EVERYTHING YOU'VE SAID IN THIS THREAD. Sorry I didn't read it earlier.

Other than plating there isn't a heck of a lot of difference between hospital grade and commercial grade outlets even as respects pricing. Material used is normally 688 brass for either the Hubbell or the Pass & Seymour so get the ones that are easiest to obtain and look for the heaviest duty ones in the respective catalog. Also look for no steel parts as some have clamps that are steel.......You can take it a further step by looking into silver plated outlets that are available through ACME and others as these do focus a bit better than their unplated P&S counterparts........Cool thing about outlets is they are cheap in the scheme of audiophile things and you might like the ACME or the fancy Hubbell that Albert sells or a combination of the two or perhaps some other outlet mentioned above as they all sound a bit different from each other....

Albertporter, how can one be so righteous about a *lack* of knowledge? I can understand a distain for engineering and science in a field like oil painting, or maybe even making musical instruments, but in a field like audio equipment, which wouldn't even exist without science and engineering??? Do you have any idea how silly that sounds?

Ya know what, I haven't had this much fun in a debate since some kid tried to convince me a grounding kit added a bunch of horsepower to his Honda.

Rushton! Welcome to the down-with-knowledge-fest! So let me guess, you don't know anything about electricity, electronics or psychoacoustics either?

I'm sorry, but I still don't understand. Perhaps you can educate me. Forget about electrical outlets for just a second. They're too simple for argument. Lets go with power cords. So one can measure a 60Hz AC current at a certain voltage level coming into the cord at the male end of the plug, and there's exactly the same 60Hz AC current at the exact same voltage (within .1 volts, or a loss of less than 1 part in a 1000) coming out the other end. The AC power is about to go into a transformer to be stepped down in voltage by a bunch, and then rectified to DC. Then it flows into a rank of capacitors that meter it out to a couple of amplification stages. Oh yeah, that transformer has a bunch of inches of wire in it. And then there's a bunch of feet of wire in the wall, before you even get to the power cord. Don't these wires make the power cord a little moot? Now tell me again how the power cord affects the sound of the amplifier's output? I must be missing something... can you help?
