OPINION: MATTER OF TRUST I HEAR YOU SAY?

I take it with Focal Loudspeakers being the front and centre picture in this article that Rushton wrote about a distributor "Transgressing the normal relationship", is Busisoft. Seems like Hell have hath no fury like a woman scorned!

https://www.stereonet.com/au/opinion/opinion-matter-of-trust/

He has a hide to talk about "TRUST" when his moderators have been undermining paying sponsors for years. Perhaps Busisoft got tired of his constant pushing of Harmon products and thought their sponsorship payments weren't really getting them any value for money.

Who knows, but TRUST does not appear to very high up the list of priorities. Look at what he has been allowing his moderators to get away with. Its all there people, dates, names, comments, everything.

I've heard the other side of this story and it's at complete odds with what is written in this article, so much so that it reminds me of an episode of Minder LOL This article smacks of sour grapes over someone who was no longer willing to pay their protection money to the stereonet coffers ! Good on them for standing by their own principles and not let themselves be bullied by thugs !!

cheers

We have split this thread up into two threads because we though the remaining posts deserved their own thread and rightfully so !! Click here to see the other thread

With over 60,000 posts to their name he or she should have been banned and not demoted. Anyone else spruiking or continually plugging a particular brand would have been pulled up very quickly by the owner and either warned or banned outright according to their own forum rules and yet nothing happened even after complaints were made years ago I too more or less got banned for only writing two sentences that the owner of stereonet did not like as well as having the only thread on my product completely removed so go figure !! He guards it like a hawk and yet this is allowed to go on for years

Do these people honestly think that Australia is like the wild west and they can do what they like with impunity and absolutely no accountability ?

And that other monsieur coffee making character that appears to have written that damning PM with his phone number on it doesn't get let off the hook either !! He's up to his neck in it as well.

cheers

Which ever way you cut it these are still electronic devices which process electrical signals and need to be treated as such no matter how many flashing lights and buttons or how much they cost or how easy to use !! Without valid measurements these types of reviews are not worth the paper they are written on and are no more than someones opinion and likewise with the nonsense that is published by stereonet. There are only a handful of publishers that possess the relevant test equipment needed to evaluate equipment properly such as stereophile, ASR, Australian Hifi and to a lesser extent HNRR. The rest of them are either a waste of trees or internet bandwidth with stereonet no exception

Honestly speaking reviewing an amplifier without at least testing its power output and/or distortion, FR etc is like reviewing a car without driving it. There is only so many times you can wheel out the same old sound stage width and depth cliche before people wake up to the fact that they are just reading propaganda designed to suck then into buying something which is what websites like stereonet are designed to do Some of the best reviews I ever came across were from Audio magazine which would not only measure and listen to equipment but more often than not would often discuss the underlying technology using either a full or simplified schematic diagram provided by the vendor

Having said that there are still some uses for a plain vanilla descriptive write-up of gear even if it is ones own opinion especially if there are some decent pictures of both the insides and outsides but I wouldn't really call it a full review unless it was accompanied by some decent measurements in order to confirm the manufactures specs

I didn't know moderators were supposed to be in charge of sales ? I thought they were just supposed to police a forum and not get involved with promoting selected brands at the expense of others but this betty boop character just can't help him or herself The question here is how many prospective sales have been lost because of the continual promotion of this one competing brand by this particular mod ?

cheers

Check it out. Just more evidence of the cover-ups ! I dug this up from a past facebook messenger chat back in 24-Apr-2019 I was having with the owner of stereonet when I was still on speaking terms with him, Apparently it's always a conspiracy theory and he is in total denial whilst the evidence above paints a completely different picture. What's even worse is he allows this brazen activity to perpetuate even at the expense of other paying sponsors whilst silencing any dissent on his own forum. I'd say busted Marc - well and truly ! The game is up ! How many local businesses have been ruined because of this nefarious behaviour ?? I hastened to think This is not what Australia needs or deserves

And for those playing along at home even if you write stuff he doesn't approve of on another site but has no control over it, you will surely get threatening emails with fake legal threats at all hours of the night as I have got from him. He will never debate anything in public he does not feel comfortable with and that's why so much gets deleted on his own forum.  For those not used to this type of corporate bully tactics you need to see through it for what it is and don't fall for it

Talk about shooting the messenger !! Let me get this straight. You reported this clandestine operation to the forum owner and instead of reprimanding or standing down the mods involved he then bans you and deletes all of your content whilst allowing the same mods to keep spruiking the same brand of equipment, till this day, and at any opportunity for a brand that for all intents and purposes is not a payed up sponsor ? You'd have to be totally daft to pay this forum owner 2K a year only to be compromised by this sordid arrangement. And yet nobody is allowed to say anything for fear of being banned or like myself have posting and PM rights removed

And for 2K a year just to have some iddy biddy forum space allocated to your brand and as soon as you stop paying your renewals your forum space and all of its posts disappear into the ether whilst this same vendor keeps getting continual free plugs at every opportunity. You've got to be kidding me, this must be noddy land

That was the plan but unfortunately time isn't on our side with the new orders for the preamps. Having said that I use this amp daily and it eventually has to go to the original customer who also ordered a UPP a while ago. Also because there are so many people making these things now and competing on price the urgency wasn't really there. Having said that our amps way a ton due to the stainless steel case and 10mm thick heat spreading plates which is why we can drive then at full power and they don't even break a sweat. Many of the lesser designs try and use a bit of flimsy case work as the heat sink. Not good for long term reliability. I wanted to make ours bullet proof but it has also made them much more expensive to build than other offerings

Also this particular amp had some experimental features incorporated into the design which are not seen on any other amp but will be removed to simplify the design in any future revisions. I do have some parts for two more of these amps to put together when I have some more time.

Ok i thought perhaps the search doesn't like the hyphen between analog and precision in my URL so just did a search for 'precision.com' and see what happens. So ch-precision.com is searchable but analog-precision.com is not. Someone with sour grapes here probably because I refused to pay my protection money

[Download link to deleted thread below:]

One astute reader contacted us recently and asked why there was nothing on stereonet about our products as he was interested to find out more and get some user feedback but told us that the forum search always produced no results when searching for 'Analog-Precision'? so we had to investigate this for ourselves. For those not familiar with stereonet it is nothing more than a glorified advertising platform masquerading as some kind of 'hifi community' with the members being used as its captive audience but it is anything but a hifi community with its draconian style of censorship and restrictions unless you are willing to pay the $$$ to have some of them removed

Anyway check it out. It seems the reader was onto something here with a search for 'Analog-Precision' yielding absolutely nothing. Maybe I have got the spelling wrong but I checked numerous times and each time it yields 0 results. So the plot thickens



Perhaps it is not returning a result because there is nothing to find ? I told the reader who contacted me that they probably didn't find anything on stereonet because we have been blacklisted and the only thread that was specific to the Preamp has been completely removed by the owner of that forum, however I had the foresight to grab a copy of the thread before it disappeared and have provided a link at the end of this post where you can download it. The reason why this happened is that I believe the owner of that forum and one of its paying sponsors tried to undermine our business by attempting to siphon away prospective customers from us at a critical time of the pre-order for our 2nd generation Preamps. When I complained about it on this forum I received a very abrupt and threating PM from the owner of stereonet requesting that I remove a couple of statements which I refused to do and the rest is history ! Neither statements had anything to do with the underlying issue but more about the so called reputation of the owner of stereonet. 

You will also notice that we have not been added to their list of Australia made product websites even though we probably make one of the most sophisticated and technically advanced consumer audio products in Australia at the moment ! Apparently our website was added only for a very short period of time before it was pulled again ! Check it out analog-precision is missing in action !



Perhaps they don't think we are worthy of any addition because in the owners own words we are just a bunch of 'hacks' struggling to get something to market whilst the owner of stereonet was hatching up plans with one of its paying sponsors to steal away prospective customers from us at a critical time ! And I am glad he agreed that our product works because I don't think he has ever created anything himself or understands how difficult it is !



Having said that, there are still some remnants and old posts that refer to our product or website on stereonet but we had to dig hard just to find one of them as the search engine has been crippled for anything to do with us !

To prove the forum search is not broken let's try some other search terms such as 'minidsp' which I believe is not a sponsor but gets plenty of free plugs every day and all day long. Go figure ! All 22 pages of search results which reference this particular brand !! Not bad for a vendor that doesn't pay a single cent of sponsorship !



For what it is worth I had the foresight to take a copy of the only thread about the Ultimate-Preamplifier Mk-1 before it had been completely removed and have made it available below as a pdf download below including the owner requesting that I apologize to him which he later retracted from that thread before he removed the thread altogether! I won't be apologizing to him for anything as he has a number of apologies to make to others before he seeks redemption for his own misdeeds.  Funnily enough I wasn't banned outright although I can still log on but not post or access the PM's but this was a while ago and I haven't checked since !!

Below is the FFT Specturm of the output above (Note that any artifacts are buried below -160dB !!)

[Test Methodology:]

Test Methodology:

In this test we are looking at how the DAC is good at resolving very low level signal levels or in other words its micro-dynamic resolving capability. In this case we feed each channel a low level digital signal of -90.31 dBFS which corresponds to a full-scale (0dBFS) signal divided by 32768 or a reduction of signal magnitude by 16 bits which is the lowest level for redbook CD ! This is a 32bit DAC so still has plenty of bits left in the tank to resolve this detail

Conclusion:

Even with a reduction of level equivalent to 16bits in magnitude we see the Ultimate Preamplier has no problem and resolves it cleanly compared to the DEQX Premate which adds a lot of noise and distortion to the signal.

Below is the real time capture of the Left and Right Channels of the Ultimate Preamplifier at -90.31dBFS @ 1kHz 24 bit WL. Compared with DEQX above the output of the UP is significantly cleaner !



Below is the FFT Spectrum of the Ultimate Preamplifier output. Compared with the DEQX above the noise floor is much lower on the UP !

[Fig.12 DEQX PreMate, HF intermodulation spectrum, DC-30kHz, 19+20kHz at 0dBFS into 100k ohms (left channel blue, right red; linear frequency scale).]

Fig.12 DEQX PreMate, HF intermodulation spectrum, DC-30kHz, 19+20kHz at 0dBFS into 100k ohms (left channel blue, right red; linear frequency scale).

Note how the noise floor is lifted up and modulated by the two tones whereas this is totally absent in the UP spectrum ! Again the UP wins hands down when it comes to transparency !



The following test results show that the IMD distortion of the Ultimate Preamplifier is exceedingly low and betters the performance of the DEQX Pre-mate by a long margin !
