Use a piece of music from mid to late 1980s, non-remastered, so no "loudness wars" and overcompression to worry about. Rip resultant recording to FLAC or high-bitrate MP3 (let's say that MP3 achieves transparency somewhere around 224kBit, let's make them 320kBit). Upload to web site somewhere, post URLs on here. Allow people to listen and attempt to determine which one was the freebie and which one was the "expensive" interconnect.

Allow people to listen and attempt to determine which one was the freebie and which one was the "expensive" interconnect. The above approach would mean each individual's reponse would have a 50:50 chance of being 'right' purely by random. Thus if a number of people participated the results could be characterised (inappropriately) as "X percent of people could tell which was which" when the result might simply be due to chance. It might be better to have a number of 'recordings' so each individual could have a number of tries. Might also be better to provide trios of recordings, one with one cable, the other with the other, and the third with a randomly chosen cable. An alternative would be to use either the same - or different - cables for the L and R channel, and see if anyone could tell. :-) Then we might be able to assess if the results had any significance.

That sounds good except that I'd prefer a wav file and a reference to the original CD so we can compare with that too. -- Eiron. |

No one is a fool for being skeptical. Many of the claims in audioland
are quite foolish indeed. Yet in a high resolution system, power cables and interconnects can make a difference. Not always an improvement, but a difference. A large fat power cable can augment an insufficient power supply in a real world power situation. Admittedly not the right solution, but it can help. I recently changed the IC's in a Quad 306 power amplifier (TI's to Burr-Browns) playing through some Quad 988s. My wife (not an audiophile), walked in the room and immediately asked what had changed... "it sounded more alive" was her comment. |

There simply is NO op-amp in the signal path of a Quad 306 - the circuit is entirely made from discrete transistors. So you fell for one of then dumbest SCAMS on eBay. You ridiculous PITA moron !! ....... Phil |

Not always an improvement, but a difference. A large fat power cable can augment an insufficient power supply in a real world power situation. Admittedly not the right solution, but it can help. People often make such claims. Usually on the basis of not having done any test whose results could be assessed for reliability, nor having bothered to ensure that the many well-known possible causes of error were dealt with. Thus making the claim worthless. I recently changed the IC's in a Quad 306 power amplifier (TI's to Burr-Browns) playing through some Quad 988s. My wife (not an audiophile), walked in the room and immediately asked what had changed... "it sounded more alive" was her comment. Comment much as above. It is a common experience that what we hear 'changes' from one situation to another. Afraid that simply isn't a basis for deciding *why* a 'change' was heard. Far too many other possible causes or reasons which your simple anecdote fails to deal with. Or are you saying you had her repeatedly walk into the room, having switched at random between the two types of IC? And that you carefully arranged to always play the same music at the same volume? And that you changed nothing else whatsover? And that she always walked in by the same path, to the same position? etc, etc... Slainte, Jim -- Change 'noise' to 'jcgl' if you wish to email me.

It is a common experience that what we hear 'changes' from one situation to another. Afraid that simply isn't a basis for deciding *why* a 'change' was heard. Far too many other possible causes or reasons which your simple anecdote fails to deal with. BTW I just looked at my copy of the 306 diagram. If you are referring to 'IC1' (TLC271) then you might like to note that IIUC its role seems to be to null the dc offset of the amp. The 2M2 resistor (r33) and 680nF cap (c3) mean it only really does much around the 1 Hz region and below. You loudspeakers (and wife) are remarkable if they can hear this. I'd also be curious to know what recording you were playing that had something audible at such low frequencies. Of course, since you didn't give any sign of establishing that your 'test' had any value, it could just be that you and or wife are simply mistaken. It does happen, I'm afraid, even for the wifes of audio fanatics. :-) Slainte, Jim -- Change 'noise' to 'jcgl' if you wish to email me.
