I cannot think of a single situation where a gold plated fibre optic cable would be beneficial.

In fact, having the gold tip may result in more unintended reflected light, which is exactly what you don't want in a fibre connection.

I find my stereo sounds significantly better when I'm half-cut, so there might be something to this!

What we should do is set-up a blind tasting session where you don't know whether it is Tennent's Super or Gin crafted by monks at the top of a mountain using nothing but the happy tears of school children. (Sad tears taste bitter.)

@crackie - I presume you're just saying that you believe that "Music and it's complicated harmonic structures is a hard thing to replicate"?

As for power purity - ironically, night time is when most people are likely to be consuming power (in a domestic environment) so that's more than likely when mains would be at it's noisiest.

However - I suspect that late night listening is enhanced by the drop in ambient sound levels rather than 'purer' electricity.

It is noticeably quieter at night (certainly around here) as verified by a dB meter.

I have a cheap optical from Amazon which is plated on the connectors. I actually think the plating improves the cable, only because I find the tiny little notches that click the end in place often wear so they don't stay in place as well.. probably just as easy to achieve withh better plastic

I ran a Cinepro 3k6 SE for many years, it used to have really low level hum you could hear with your ears against the speakers, until it got to around 11pm at night, it slowly reduced in volume and by the time 1am arrived it was silent.

However...........as the hum went from the speakers the voltage also increased, from around 218v up to 235v and I then got some mechanical transformer hum.

But, it does show that mains makes a big difference.

Mains makes a difference if and only if the DC supply circuits in one of your components has been designed by a chimpanzee. There's just no excuse.

No, that's just poor power supply or amplifier design - or - that amp was optimised (or even configured?) for 240v operation, and 218v was simply too low for it..

I suspect that as the mains voltage dropped, the quiescent current of the amp went up, loading the power supply excessively and causing hum.

Mechanical transformer hum is caused by DC on the mains, or it could simply be poor quality transformers.

I guess it's not inconceivable that as your mains voltage went higher, that the DC level increased (or possibly just appeared it not there at the lower voltage).

In my experience, you can hear and measure, a lower noise floor in the early hours relative to daytime hours and the evening time.

The differences are not subtle and have been noticeable with every piece of equipment I've owned. Mains borne noise was bad when I lived in Huntingdon; daytime noise was industrial particularly bad. Domestic noise was pretty bad in the evenings too and noticeably improved as the evening progressed; in the early hours of the morning the background hash of white noise is almost inaudible.

You can measure your noise floor using freeware like this http://audio.rightmark.org/index_new.shtml

Companies such as Accuphase, PS Audio, Isotek, manufacture mains 'regenerators' to tackle the issue.

I started a thread on PH about the subject in 2009.... https://www.pistonheads.com/gassing/topic.asp?h=0&...

Hi Tony, I should have clarified........when I said at night I meant in the early hours of the morning rather than 'late in the evening" used on the Fb link.

If a CD player or amplifier reacts badly to a poor quality mains feed, then something is wrong with the PSU design.

Any well regulated, well smoothed (in particular well smoothed applies to amplifiers which typically don't use a regulated PSU) should be relatively impervious to anything but the most severe corruption of the mains waveform and voltage (within reasonable limits).

This applies even more so to devices using SMPS PSUs.

Even when I lived on a farm in a rural part of SA my TV (big old CRT TV) would only occasionally flicker because the mains wasn't always particularly stable, so what makes audio stuff so special that it's not immune?
I'll tell you what makes audio so special - the 'special' golden ears brigade, that's what!!!

As for that PS audio review - the clipped mains waveform shown in one of the graphs is likely caused by something on the local mains ring, and additionally will (should!) have no affect on a competently designed PSU. Curiously, the PS Audio is quoted as having 2.36% THD (2nd and 3rd harmonic) and that amount of THD would be visible on the waveform, but yet that depicted in the image is supposedly perfect.

In fact, that device is truly fitting of this topic.

Well if hum and noise is such a problem why does top-end gear still use unbalanced interconnects?
It is an appalling way of connecting things together in an electrically noisy environment!
