Often the large speaker setting is for 4 ohm speakers and small is for 8 ohm. On my receiver there is a separate setting for subwoofer crossover frequency.

Your speakers shouldn't be more than 8 feet apart, and they should stand out from the wall a couple of feet. Don't put them in the corners of the room or they'll couple with the wall and cause problems.

No, "large speaker" settings are for crossover frequencies. I've never seen anything to do with the nominal impedance of speakers besides the outputs of tube amps. His speakers appear to be near field, in which case those dimensions dont apply. I may be incorrect though since the picture is kind of dark and fuzzy.

Maybe I'm misremembering. I had some sort of setting in the rabbit warren of menus for 4/8 ohm. Perhaps it was a different one.

It does not :D

HA! Yeah, that's worked for me too. biggrin.gif

I think I've had my fill of cable talk. which was good fun and all, but I'd like to turn our attention to.... power supplies. I've read some claims about "clean power" having an effect on sound quality. One member has a bevy of usb battery packs that he claims provide varying levels of this mysterious "clean power" and thus changes in sound quality are discernible (according to him). I don't know one way or another, but I would like to hear some facts on this. Would anybody care to enlighten me?

Sorry I really don't know any facts regarding this. I am in fact, going to ramble about this. So, yeah.

But it seems a bit like poppycock to me. I can however imagine how this myth started. Someone probably had some kind of device that was screwing with the ground, something like a laptop, or maybe a senseo device. When plugging the a laptop into the same outlet splitter as let's say a dac or amp, there is an awful buzzing sound. I bet something like this made some guy go haywire, and plugged the devices into some sort of battery, but without the interfering device. There is some truth behind it, but they forgot about a very important variable, a confounder if you will. Which was, a device messing with the clean power supply.

If your stereo is plugged into the same circuit as a refrigerator or air conditioning unit, you might have problems. But if your power isn't causing buzzes or pops, there isn't any need for a power conditioner. It certainly won't improve sound quality.

Some of it, for sure.

 

Here's a bit of detail on power conditioning, grounding etc.

Good question, I just like to invade discussions with my opinion I guess...

That "power conditioning & grounding" page has lots of problems.  Mostly it's because the page co-mingles ideas about connections to Mother Earth, Safety Grounds (Protective Earth) and audio system common.

Yes, but those grounds get comingled in real life as well. It only takes one device to "break the rules".

Care to elaborate on your comment?

Prog Rock Man, you're a beauty. Blind tests are the only way to get truly valid information - especially in a kind of 'science' where so much is dependant on the perception of the user. Extremely useful info - especially for newbies, so you have starting point on where you want to put your efforts into getting good gear that actually makes a difference, & what kind of sound qualities you want to get out of your listening experience.

 

Brand influence is huge - and what's even bigger I'd say is 'people' influence, i.e. buddy A says that a certain brand of headphone has a warm sound, wide & diverse soundscape - and when you listen to the headphone your look to hear the same thing.

 

Best way to get bang for your buck in audio equipment - go to a store or convention - have a buddy put headphones over your ears without knowing any details except what you can hear and feel when they are on your head. Listen to all the choices, write down your favourites on a scale of 1-10, make a decision based on balancing cost of phones with that score. Profit $$$$

A convention maybe, a store hell no. So much chaos, noise and no time to properly test every headphone! I need atleast a couple of days before I really 'understand' the sound signature. Ok, if choosing between low/mid end headgear the choice would probably be a lot easier, since the differences between headphones is bigger in that scale.
