Re: The *NOT BORING!* Hi-Fi faff and sales thread
I havent got the time to right what I would like to about mains conditioners and the like. Usually the hum can easily be traced to a faulty cable or a dodgy connection.
Most 'noise' from external sources such as washing machines and fridges etc can be cured by installing a separate ring mains at the consumer unit. not too expensive.

Three thousand quid, you say? Good grief, you have to wonder how a bunch of electronic components that clean up a sine-wave could possibly cost so much. But if you do ever make one yourself, I'd love to hear about it!

When I pulled out the powerline LAN adapters, that noise disappeared. So I'm pretty sure that I'd nailed the culprit. But it meant that I had to choose between a reliable broadband connection or a silent background for my music. This mains conditioning unit lets me have my cake and eat it.

You're absolutely right LGF, and if the noise had sounded like a transformer hum, then I certainly would have been checking cables, earthing and such like. But the noise coming from my speakers sounded like this video clip between 0:09 and 0:20...legrandefromage":38kvvujm said:

Interesting idea, but I think the landlady might object...legrandefromage":38kvvujm said:

I think what LGF is saying is there is no magic about this.
Powerline (TM) components are known to be noisy. Us in the EMC community (I run an Automotive EMC test facility for my day job) have a long and painful experience of them. They were illegal for ages and then became legal simply because of demand for them (go figure), and are still illegal AFAIK in commercial premises because of the noise they imprint on the mains power supply.
It's not at all surprising that the noise from them is audible on your hifi. It will get through on the power supply, but rather than getting on to the music signal from the power internal in your kit, it more likely induces through cables and PCB tracks. Op Amps in your hifi generally have massive PSU Ripple rejection in the order of 100dB>, so any noise on the PSU wont appear on the O/P, but I digress.
A mains filter can be had for a tenner, and a lot of hifi will come with them built in. There is nothing to be gained by spending hundreds, or thousands on 'mains conditioners'. Snake oil. Like fancy cables made from unobtanium, or pens to paint your CDs green, or special feet for your amplifier. It's BS, save your money for records or CDs, or the biggest improver of sound quality on earth - beer.

Re:
The 90's called and said they wanted there stereo back lol
Just thought I would share my latest purchase Denon components with Tannoy M3 speakers , really like the black with silver feet. Just need to find the matching equalizer
Just finished cleaning it all and it was filthy but looks so much better and has the glossy finish again
Any comments welcome and thanks to LGF for starting this great thread
Thanks Dave

Re: The *NOT BORING!* Hi-Fi faff and sales thread
Heres a quick snap-shot then.
From the top down:
Technics SL-1410 MKII
Yamaha Music Cast server/streamer thingy - sounds 'better' than many CD players I've owned. It can record lossless which is nice...
Old region free Cambridge Audio DVD and LG blu-ray
Rekiborter's Sony for the Blu-ray/ Sky duties. It interacts with the TV/ Blu-ray player for convenience. It runs those small MS speakers and a hidden Yamaha sub. 48khz audio sounds great whereas 44.1 does not, soooooo...
...we have the Quad 44/ 606 stuffed onto an out of sight TAG McLaren prototype AV32R. The Music Cast is fed to that digitally with the 44 used as a phono stage for the SL-1410. The 606 feeds the Mission 753. They have been my bench mark for 20 years. Other equipment sounds better or worse than. Very few speakers have bettered their particular 'sound' for the music I listen to. I suppose we have grown up together.
Then on the floor we have an old Ipod from 2004, a Technics SL-1510 and the SL-P1200 CD awaiting my wizards sleevery...
