These posts say it all.

Yep someone else with a similar problem to my earlier pre's. It can happen with high efficiency speakers ;) The moral of the story is don't throw stones in glass houses ! Anyway I silenced it completely in the later preamps ;)

The DEQX in use by Barry emits a hiss that?s close to audible from the listening position and potentially nullifies some of the Select DAC II?s improvements over his existing MSB DAC V.

Audioweaver is not hard, they are just not smart enough to know how to use it.

Or simply they don't want to legitimise its use because I use it in my products :( I noticed the US dude who has a competing product to mine only lasted one post and the person who was trying to promote it is now banned. He should have tried his luck promoting an integrated valve amp because he would have had more luck ;)


Don't waste your time with those guys. They are part of the same club and we aint invited. They will take any opportunity to sink the boots in. And btw they were still using the noisy versions of those cheap DSP products when I released the UP2 and UPP. Anyone who is serious about designing multi-way loudspeakers will use Audioweaver over the canned solution provided by those low-cost offerings any day of the week. The flexibility that Audioweaver offers is just not there with those low-end offerings. The fellow who bought the last UP2 was up to speed on Audioweaver and had his AWD file ready to go before he'd even taken delivery of the preamp 😉

Not only that, with the UPP you can scale up the DSP processing capability with no effect on the audio performance or measurements and is totally transparent to the audio chain no matter how noisy the PC you are connecting it to ! Not only that, the same DSP chain is there for ALL sources including analog sources such as tape and phono 😉 See if those low-end offerings can do that ? I don't think so and yet they will sit there and continue to nitpick and bitch over one problematic customer that I had years ago with the first gen preamp and who made every effort to destroy my reputation. They are good at that. They all know each other and we aren't part of their club.

Some good news is that we will be offering a special edition of the UPP ie the UPP(SE) with even more tweaks and refinements as well as a slightly different case and guess what ? It will be even more expensive but well worth it compared to one of those expensive imported do-nothing benign stereo DAC's that are paraded on that forum all of the time. As you know with the UPP you have access to Audioweaver on both the on-board and external PC of your choice which is unprecedented. For those into FIR filters this is the dream solution for them and with multi-core CPU?s from Intel and AMD this is FIR heaven ;)

PS It's good to see stereonet promote more chinese made stuff such as the nearly 300 page thread on that Chinese made valve amp. Wonder how much sponsorship those dudes have paid to date ? Too bad if you manufactured valve amps here and were up paid up sponsor to stereonet. :(


I wonder if Rushton will inform the Victoria Police and have me charged with a criminal offence because I used a carriage service to say that he couldn't design an amplifier?

But he might call the Thought Police and have me arrested for thinking too much because the last thing you want to do in this country is to think too much and invent and manufacture things because you deny importers their pound of flesh and you know that you can't have that can you !! This is what happens when you try and do what I have done here in this country:-


You have no way to defend yourself on his forum because if you stand up to him and his denial bullshit he bans you just like he did with me when one of his mods offered me cheap Elektra amplifiers and denied it after I sent him the proof. He doesn't mind kicking you when you're down and has demonstrated this on many occasions. That's just who the guy is.

I think AudioGeek is a bit of a piss ant loser who took an opportunity to get a kick in for him. It's a pity he didn't have something truthful and constructive to contribute. He's a bit of a bullshit artist too by multiplying "one" to "some".

I was just having a dig around as to who this AudioGeek dude is and this is what I found. Has owned both Elektra and Red Spade gear in the past so I am not surprised with his attitude towards me. These are two dudes that I have had issues in the past with and not through any fault of my own. They are monumental time wasters and game players. I was just minding my own business whilst getting sucked into their web of deceit. One was a perennial phone caller over five or more years abusing my relationship with him so he could get free information from me whilst holding back on everything he knew. The other one's partner wasted my time over a period of 12 months wanting me to build a DEQX work-a-like for him at great expense to myself  and when I finally had the germ of a prototype ready to test with his horn speaker system, he totally squibbed it and ran away. Probably if I had of tested it with his system I would have picked up the problem with it that got carried through with the later gen1 preamp which was subsequently corrected in the gen 2 Preamps :( But no not with these guys. They do nothing except throw roadblocks in front of you. :(

These people call themselves "entrepreneurs" but are anything but entrepreneurs. They have no concept of risk and place ridiculous expectations on others who are expected to take on huge amounts of risk whilst they risk nothing themselves and expect to take most of the reward which is quite a common theme in Australia. There are a few others I have dealt with who have engaged in this type of activity too. They go around with begging bowls wanting major designs done for them with virtually no money down. Ironically, they charge top dollar for their own products. I hate to be a whistle-blower for these types but I have seen it all before in other businesses so this AudioGeek dude needs to get his facts straight before throwing stones in glass houses. He needs to try his own hand at a design like this and then he can criticize.

The Dark Room / Good to see 'Australian Hifi' take back the Hifi Show ;)
« on: September 12, 2022, 05:18:20 PM »
Hopefully we will see them back in Melbourne too ;)

See if you can find this on stereonet ? I almost missed it when I was reading the latest "Australian Hifi' mag and then I had to read the full page spread a few times to realize that Dennis the menace had nothing to do with it ;)

However note the date on stereonet. 1 month before the Aus-Hifi show in Sydney ;)


Check it out. Seems the stereonet website looks a bit more crippled than at first glance. Try finding all of the posts of a particular user from their profile and you can't seem to get past the first page of search results and it doesn't matter who it is either.

However google is your friend here. Lets find all of the posts by user joz that also contains the brand 'elektra' which apparently is not an official sponsor. We enter the following " joz AND elektra" into the google search engine or simply enter it in the address bar and we find there are no end to the results. Not bad for someone who isn't a paid up sponsor ;)

Just to add:-

11. Surrounds themselves with sycophants and Yes men.

The irony is that you've been banned for trying to  expose it and I have been banned for publicizing it and yet the two mods that were responsible for promoting that scam are still active members on his forum with happy snap pictures of them at a recent stereonet AA meeting at some members place. Go figure ! To add insult to injury he then tries to bury the evidence with a vexatious law suit which attempts to blame me for posts made by other people which he ridiculously expects me to delete whilst having no control over them. Honestly, does the owner of stereonet really think that everyone is that stupid ? Does he really think that Australia is like the wild west and he can do anything he likes with impunity and with no repercussions just because he has total control of a public forum and what is said on that forum ? Well no he can't and that is the whole point of these threads on this forum  !

Performance and Measurements / A question for DEQX owners ?
« on: September 09, 2022, 08:12:49 PM »
There are some privileged people who now own Klippel Near Field Scanners (NFS) which is quite an expensive bit of test measurement kit and which can cost up to $100,000 depending on options. Having said that, this device can do a near field scan of a loudspeaker which is just a fancy way of accurately measuring the frequency response of a speaker without using an an-echoic chamber.. But the downside is that it can take anywhere from 12 to 16 hours (according to a recent factory tour of the Magico facility) or more to acquire all of the data and that is the price you pay for not having access to an an-echoic chamber. This begs the question as to what DEQX are actually measuring and what have they been telling people they have been measuring all of this time when they stick a microphone in front of a speaker and do a 5 second sweep and then claim to apply an inverse convolution filter to fix up both amplitude and phase issues ? The correction is only as good as the measurement right ? What is it that they are measuring and what is it they are correcting ? Does anybody know ?

Check it out. You just can't make this stuff up !


Then perhaps the author of that post should read this unsolicited email (copy shown below) from the owner of stereonet who decided in the end to make up his own legal letter full of vexatious and baseless allegations as well as threats of jail sentences and then send it to me in a last ditched failed attempt to have me remove incriminating evidence that was written by someone else, when all of his lawyers threats to date to have me remove this evidence against his website had failed !  That's right, that is what he does. If he can't silence you by banning you on his own forum his tentacles will reach out to other forums to try and have you silenced and/or removed. Guy's so tell me who really is the unhinged one here ??

And just to set the record straight there was only one complaint from all of the first gen Preamps I had sold to date and that was from a diyaudio member who had ulterior motives and was in bed with a local amplifier manufacturer that was building amp modules with dubious input stages so this poster is making stuff up about us. The irony was that I didn't want to sell a Preamp to this guy in the first place because I had had other inquiries way before him but he kept pestering me to sell him one which I did in the end and I paid a very heavy price with this guy :( He was nothing but trouble from the day he got the Preamp as well as being totally uncooperative in chasing down the problems. :( And what wasn't apparent to me at the time of these continued complaints canvassed on the diyaudio forum was why this so-called offender would not return the Preamp to me for at least 6 months and/or with one of his problematic diy amplifiers so I could evaluate the actual problem in the lab. Well it appears the Preamp wasn't in his possession for some time as evidenced by pictures of his setup on diyaudio. In fact in the end, I realized they were trying to cobble together their own DSP based Preamp by copying ideas from mine and incorporating that in an outdated DAC/DSP/Preamp they used to sell whilst at the same time trying to put me out of business by spreading malicious lies. Sound familiar ?? In end I did end up getting one of these amps from someone else who was building one and wanted me to check it out for them. Guess what ? The amp and my Preamp worked flawlessly together with no problems. I guess that's why they did not want to send me one of their amps to test it with :( This is what they do here in this country and before people start throwing stones in glass houses they need to get their facts straight because there is a lot that goes on in this industry behind closed doors that is purposely hidden on that stereonet forum and nobody can speak out and say anything for fear of being banned and having their posts censored or removed :(

Not only that, when I did get the Preamp back I gave it the once over and on-sold it immediately to someone else overseas who hasn't complained about it since ! Apparently all of this makes me unhinged !!  Having said that, according to this audiogeek member on stereonet if you produce a product and later find out some things that could have been done better because of the lack of information in a chip vendors datasheet etc you shouldn't be given a second chance but a vendor like DEQX who has been peddling the same old bit of rope and substandard equipment to the punters for decades, should be given a second chance always. Well guess what, they got caught out !! For all of this time they couldn't even be bothered upgrading their first generation SHARC DSP to a 4th gen part as used in the UP and you know why ? Because they knew they could get away with it and nobody would question it until I exposed it. But it never ever occurred to me to use a part introduced decades ago back in 1996 and not recommended for new designs ! I just used the best I could get at the time and brought myself up to speed on it even if I had to go through some revisions and iterations to get there. Now they have been caught out like a rabbit in a spot light and they are playing catch up games, and if it wasn't for what I published on this forum they would still be selling the same old bit of rope to unsuspecting punters like AudioGeek. If telling the truth and attempting to defend my name makes me "unhinged" then that is a noble title to be had !

And then there was their lame excuse for not offering a stereo 4-way capable DSP crossover which the UP is. I think it went like this:- "Who needs anymore than a 3-way speaker ?". Erm ever heard of a Duntech Sovereign or Dunlavy SC-V or SC-VI or are You going to tell us Dunlavy didn't know what he was doing ?

And sorry to disappoint those people if I come across as "unhinged", contrary to your opinions, we did take another bite from the cherry and produced a second generation Preamp, and the new measurements don't lie. We nailed it but let's keep waiting for the DEQX revolution because why ?? An aussie past time to kill off another prospective manufacturer and then replace it with yet more imports :(


Did a search today and now get the same results as the google site search. The search results seems to change based on what is posted here :D LOL And it happens to be the threads that points to the diyaudio forum where I had problems with one customer. Funny about that. Everything else has been deleted !


The thread link I posted way back in this thread has now been edited and the following post removed on stereonet forum !

To prove this they still left behind someone else's post which requoted this post ;)


The plot thickens with the Stereonet search for 'analog-precision'. Some changes have obviously been made to the forum search and/or forum software. This time the search now instantly returns a result for analog-precision but only returns results with 'analog' or 'precision' and not the hyphenated word effectively making the search useless again.

However you may have more luck with the google search engine trawling through the site. No doubt these threads will mysteriously disappear too because he wouldn't want people finding their way back here to read all of this ;)
