Has anyone else seen this web page advertising an 'upgraded' power supply for GSP products?: http://www.fidelityaudio.co.uk/graham-slee-accession-24v-low-noise-psu-4004-p.asp?gclid=CN2Q6NLXw80CFeUy0wodb_kLhA Could be a bit misleading as it is called a 'Graham Slee Accession 24V PSU', but is obviously not made by GSP. Has GSP authorised this or has anyone actually tested it and can comment on its value? Would be interested to hear Graham's comments. Thanks ------------- Russell |

Yeah it is rather misleading - deliberately so imo. I don't suppose they are legally required to be licenced or approved by Graham or any of the other manufacturer's. It's a PSU and if it works, then it works. Whether it's any good is an entirely different question. Virtually every PSU for every manufacturer is illustrated with the same pic. Looks like a nice box, but who knows if that's what you get. I don't know these people, maybe they are legit, maybe not. Doesn't it cost a load of money to get a power supply approved? if so how can they offer so many? Or maybe they are the equivalent of those universal thingies you can buy at airports with a million different adaptors. ------------- Dave Michell Gorbe + HR PSU -> Cadenza Bronze -> SME V -> Elevator -> Accession -> Proprius -> B&W CM6 s2 | Cusat 50 & Spatia cables ->

I have never actually bought anything from these guys but I came across them last year and have had a good look through their website. I think it is a bit unfair to label them as 'fraudulent'. Fidelity Audio are a hifi 'upgrade' company, they modify other manufacturer's products (e.g. cap rolling, better clock chips etc) in an attempt to improve their performance. I was quite tempted to send in my Marantz CD player for an upgrade but the cost is rather prohibitive and most of the 'improvements' would be bypassed by a DAC upgrade anyway. They have labelled this item Graham Slee Accession as that is the product that it is intended for and in the description they differentiate 'our' products from those that are 'from the manufacturer'. I think they had some better pictures up before but they seem to have re-designed their website since I last looked in. I had been thinking about broaching the subject of these power supplies but I didn't think it would be a good idea as it could count as advertising a competitors product  . I have no idea if they are any good mind you. I don't know much about electronics at the best of times and while as one of these must surely be better than a switching mode power supply I have no idea what the specific details of the PSU1 even are so I can't even compare the two in theory. It's 'linear' and 24v, that's all I know  . I'd be interested to know what Graham thinks. I'm not considering buying one, I will have a PSU1 on my phono stage after all, I am just interested in learning a bit more about power supplies.------------- Scott AT150MLX > Audiomods Series V Standard > Rega RP6 > Accession MM > Marantz PM6005 > KEF Q100 / Solo UL > HD540II.

You will see what Graham thinks in relation to my previous thread from 4 weeks ago. I never read the thread as being a GSP product but does appear strange that there appears to be a one size fits all. |

| Graham Slee is a specialist, not just of audio electronics, but of their power supplies as well. I'm not shilling; simply giving respect where it's due. The best power supply you can get for his Accession is the one of his own design that comes with it; the PSU1. I was quick to label this other supplier as "fraudulent" as "Graham Slee" and "Accession" are surely copyrights of Graham Slee Projects Ltd and HiFiSystemComponents. Any other company attempting to mislead or profit from the use of his name or product names without prior permission from Graham is in breach of copyright law. If it is not officially endorsed, there's probably a good reason why. There is no mention of electrical safety and EU-compliance. A genuine PSU1 can be powered on and left like this for years, because of its stringent safety considerations and long component life expectancy. |

Just goes to show how little the EU cares about small British businesses, to be honest.
Also remember that if you use an unofficial power supply with your Graham Slee product and the product fails as a result, your warranty will almost certainly be voided.

The advert has changed from when I first saw this a month ago. It does not say it is a Graham slee product but as effectively a 'superior' product from their claim. I agree with some of the points made over the apparent one model fits all and that if it fails and destroys your GSP box you are out on your own. Also without confirmation there is little tangible evidence over quality or reliability or safety which we all value. You will also see they sell aftermarket devices for other manufacturers such as quad and naim. You are likely to be aware of the many upgrades to motors and similar for the LP12 this is the tweakers corner we live in isn't it? Is the PSU 1 the best supply for the accession as ash says? Without auditioning one I don't suppose any of us can say accepting the comments over potential safety or reliability issues. If there was fully tested and safe PSU from Graham or anyone else I would be interested; the brand loyalty would prefer from Graham of course. OL who have featured I the forum over recent specialise in providing motors for other turntables; a problem to other manufacturers seen as fraudulent? Have never seen anything though aware Arthur from F**k f**m once tried to warn me off from their platter mat alleging copywrite issues. I think there are a number of perfectly valid concern over the aforementioned supply - another is they do not allow loan or sale and return which I would have expected from a non mechanical device such as this. This alone would prevent getting anywhere near my wish list! |

Well, on the official product page, Graham says something along the lines of 'comes with the PSU1 (our best) power supply' so I was assuming the manufacturer of the product would know best, seeing as he knows it and designed it in thorough detail. Maybe I'm being naive? Sorry, what ruffled my feathers is the use of Graham's name in this product's title, as though he is somehow affiliated with it or endorses it (misleading IMO). If it was titled as a generic linear power supply but in the description were described as being suitable for use with 24V Graham Slee products and clearly marked as unofficial, I wouldn't have a problem with it. |

I think that's exactly the point I was trying to make when I started the post. It should clearly say 'F******y Audio PSU' and not Graham Slee Accession etc. I think it's also a bit of a cheek showing a photo which is 'for illustration'. In other words, what you buy may not actually look like that! On 'demagnetising' gadgets,is there not a company called F***tech producing a device that claims to work on cd and vinyl? Has even had favourable reviews in the hi fi press! As an aside, being fairly new to this forum, why do we put *** when naming other companies? ------------- Russell |

It's simply that as this forum is run & maintained by GSP it's considered bad form to promote rival products - in fact it's against the T&C we all agree to when logging in. However it's not so draconian that no one is allowed to use and like other gear ... but just don't go on about it here is the general rule. Likewise the deliberate blanking of other makes, maintains a degree of civility towards their product too, so that we don't seem to be openly trash talkin about them. All seems fair enough to me. Areas where GSP have no comparable product, turntables, carts, speakers etc are a free for all, but we like to keep it nice n friendly  ------------- Dave Michell Gorbe + HR PSU -> Cadenza Bronze -> SME V -> Elevator -> Accession -> Proprius -> B&W CM6 s2 | Cusat 50 & Spatia cables ->

I agree wording must be appropriate and correct. Two key issues IMO; does this mislead browsers into thinking this is a Genuine GSP products and if so is there any intent to lead people to this this is a GSP product? IMO I would be surprised if any reader who may be interested would answer yes to either. origin live are another supplier who use online facilities to promote their wares for TT power supplies and motors. Is this deemed fraudulent or misleading? Not sure whether mr rega believes his RB250/251 or mr technics his sl1200 series their arms are better than the Audiomods versions on the premise they know best as used by a number of members on the site? Whether this is a worthy superior product in any shape has been torpedoed from several angles already and indeed if would be clearly inappropriate to promoted on this site. As suggested earlier if indeed this product was a worthy improvement to members widespread use of The PSUs we regularly use it would seem a little odd it was a such a well kept secret though or does it suggest it perhaps isn't perhaps all it purports to be? |

Perhaps the saddest thing is that when I google search "graham slee 24V", this "fraudulent" alternative power supply is the first result at the top of my screen, not Graham's own excellent and legit PSU1... (￣︿￣)ゝ
