I use Servisol at work, it's a great general purpose contact cleaner. However, I've used Deoxit for my hi-fi system contacts for years and it's the business. Thanks Martin. There seem to be different kinds of Deoxit. Which one would you recommend? BW Richard.

Not really. If just replacing a standard BS 13A fuse with a special makes an improvement, that eliminates everything except the fuse itself and the contacts. I clean the contacts with Deoxit, so that ensures consistency. Changing plug types is a potential red herring. ..mmm...yes, but it eliminates the possibility of the fuse being a 'weak link' (!) in the power supply. On another issue, you mention Deoxit Martin; is it better than Servisol? Thanks.

So, has anyone compared a UK plug (fused - 'Audiophile' or otherwise), and a non-fused 'European' one into their hifi- equipment? If no difference in sq was detectable this would call into doubt the efficacy of exotic fuses ...wouldn't it?

I don’t know what some readers here expect. If I said, for example, that smearing Stilton onto plugs whilst reciting the first paragraph of Beowulf backwards - before putting said plugs into mains sockets - improved the SQ of my hi-fi, I HOPE the overall reaction would be healthy scepticism.
Why? Because if flies in the face of not only scientific principles but Common Sense.
So it is with cables and fuses (I notice, with interest, that much of the AV forums/websites now acknowledge that there is NO difference in quality between HDMI cables (with the possible exception of the give-away freebies)).
Mains cables… 400 yards of poor, noisy, cabling to the house and then a metre of highly expensive ‘audiophile’ cable is meant to make a difference? (Assuming all male-female connectors are cleaned/gold). Silver fuses? Well I could believe that if the resistance was lower than the standard fuse; (the comparison here BTW must be between the new silver fuse and the former fuse whose contacts have been cleaned). People are rightly sceptical because it flies in the face, as I have said, of received information.
I am not one of those (like Lord Kelvin) who believes that if it can’t be measured it cannot exist, but in cases like this the first port of call must be robust, unbiased measurements followed by double-blind, randomised, A-B comparisons (followed by a suitable stats test). This is the way -the only way- science can move us forward. However, the Subjective-Objective argument is an interesting one and one aired to death and beyond on various forums -especially the AoS one.
It is still possible for people to swear that they can hear a difference. The placebo effect here is very strong (read Dr Ben Goldsmith’s book “BadScience”), and this may account for these perceived differences, as may the fact that they were right all along! Science does have these exciting monumental shifts ( called ‘paradigm shifts’) but they are extremely rare!
For those of us who have lived our lives in the ‘caring professions’ perhaps we have an over-developed sense of protection/duty of care. I still think it is right to point out the inherent fallacy of such ‘improvements’, if only to stop the poor and gullible from being duped by snake-oil salesmen. What they should do is wait until there is a large enough body of authoritative opinion that ‘x’ is an improvement before parting with their cash. Unfortunately Hi-Fi mags have been less than reliable here and there is, at present, a very unhelpful attitude (“popularism”) by the general public towards experts and authority. (I am also a hypocrite here as I have often prematurely jumped in with both feet…does anyone else recall the fitting of small black sticky triangles on the upper right side of all mains plugs connected to the hi-fi - I still have one!).
I wonder which rare-earth element, randomly picked from the Periodic Table, will be the next ‘golden-ear’ must-have.
So what DO we do with people who say as the OP, that, ‘never mind what others say I can hear a difference and that’s all that matters’? Well, I really don't know. Let them get on with it I suppose (as long as they can afford it); but don’t let them persuade others(?). Don’t be rude? I really don’t know!
In conclusion, I am not saying that the Objective/Empirical model is the only one but healthy scepticism for what may appear ‘non-sense’ is just that - healthy. (Sorry it’s taken me so long to say it). …and before any potential key-board warriors get frothing at the mouth…yes I DO have silver fuses AND expensive mains cables (I am more convinced that the latter have an advantage due to screening). Do they sound better…? Certainly if the Stilton (see Para1) is accompanied by a good Port.
Yours, Bonky.

To answer my own question (above. theaudiostandard.net/post/75791)No Volumio does not support the OLED screen and power management button when using the Audiophonics Sabre DAC and screen. Best wishes, Bonky.

I was always a fan of Volumio even though I have dabbled with Moode and Rune.
However, I have a Pi3 + sabre DAC + Audiophonics OLED screen and power management button.
All the 3 players will work but, at present, I can only get Rune to work with all the features (above).
There are sites on the Audiophonics forum which allow one to download modified scripts so that the screen etc works; does anyone know whether Vol2 works natively with my stuff AND allows the PW and screen to work?
Thanks,
Richard.

Previous post:
"I bought an excellent 306 from a hi-fi shop which had all the main caps replaced. Like an idiot I decided to 'enhance' it further with a DADA upgrade. I tried it first on one channel and it didn't work. In the end I gave it to RedHill Audio of Chesterfield to sort out. The response was that I had used lead-free solder and some joints were thus poor. He fixed this but still reckoned that it didn't sound as good as his upgrades, so I allowed him to add a few tweaks of his own. I have yet to collect it and try it out..but it's against my beloved Suggie A21A.. The chap at RedHill sounds very good, friendly and genuine. (Usual disclaimers). Richard."
Well I got the Quad 306 back yesterday from RedHillAudio and mated it with my Tisbury passive preamp and I was immediately impressed! Fast, dynamic and 'weight'. Mind you I'm hard-pressed to discern THAT much difference between it and my Sugden A21A (driving efficient Living Voice speakers ('a match made in Heaven')).
I've just bought a new Cambridge audio CP2 phono-preamp and am just listening to it now - and letting it all 'burn-in'. Then I'll make a decision on which to sell on. The Suggie was recently serviced (by Sugden) and I'm rather pre-disposed to keeping it, but reality must dawn some time I suppose (?) (The deck is an Inspire Apollo + Roksan Nima + AT-0C5MC cartridge -probably past its best).
Anyway, I can testify to the 'audiophile nature of the new combination...if that's any help to others.
PS I'm still very impressed with the R Pi3 + Audiophonics sabre DAC + case + OLED screen.

Hi, I wonder if you could give me specific details re the 306 op-amp mods you envisage? I did look at the schematics of the 306 v the 909 and noticed ...from memory... A few component alterations ... Caps for diodes etc but am away on holiday at present so haven't got the exact details. I notice others envisage changing the zener diodes for faster ones ( I can give details if you wish) and also placing Schotty (sp?) diodes across the output caps. What do you think? I have just bought a 306 with all the caps replaced ...but to the original specs. All I have done so far is to reduce the input sensitivity. thanks, Richard Read more: theaudiostandard.net/conversation/1522#ixzz4G63SeJKT

Martin, Further to your excellent instructions for setting-up Volumio with the Pi, I was having difficulty with my Mac system in getting Volumio to 'see' the music files. I used this: www.hagensieker.com/styled-41/index.htmlThe only difference I had to make was in the IP address(I used for example: 192.168.1.123 instead of the smb://applesimac2.home which I got from the file sharing info)..Hope this helps, BW Richard.

Good news! I swapped the white wi-fi- dongle for an Edimax type and it worked first time; all up-and-running. Now for the NAS - when it arrives. Pimorini plugged the offending white dongle into their set-up and it would not work, neither would a replacement. It may be that there are problems with this new type of dongle - perhaps only with Volumio - they were going to test the batch with NOOB. I've asked for feedback on this and will report back if I hear anything. So, my take on all this is: buy the Edimix type dongle if you have Volumio. (See: shop.pimoroni.com/products/wireless-n-nano-usb-adaptor)Thanks everyone! Richard

Hi Pinch; thanks!
Yes, I've tried it with a Mac and another Mac running Windows7; same result: it's not recognised!
The white dongle is one with the raspberry Pi logo embossed on it. I bought it from Pimorini. On the back it says Model"WLU6332". I cannot find it on their site, or, indeed, others. I believe it to be a new 'superior' model.
Perhaps I should swap it for an Edimax type one.
Thanks,
Richard.

Thanks Martin, but what do I do next? The above was achieved using ethernet. Wi-fi is still not detected.
I'm wondering about swapping the dongle tomorrow.
I could use another micro SD with Noob/Raspian on it and hook it up via hdmi to a TV I suppose...it seems an awful lot of faffing about to get something relatively straightforward to work...
...But if I get it working with Raspian I'll still need to replace the Sd card with Volumio on it.
Puzzled...but appreciative of the help and interest.
Richard.
