$7000 for a couple bits of lossy ferrite is a bit rich !! What has this industry become

Well I just hope he had the foresight to ask Daryl Wilson the same question the Audio Bell asked him regarding the contradictory use of time alignment with high order crossovers (time into video at 742 seconds 12min 22secs). Instead of brushing it off maybe he has got an answer by now otherwise all of that fancy-smancy metal work designed to move the drivers relative to each other is totally pointless I don't think it would happen though because he would ban someone on his forum if someone asked that question LOL.

Mick, I genuinely appreciate your apology and yes, it does take a lot to suck it up when you do realise you are / were wrong, so I am grateful.

 

You can imagine my surprise when I discovered the conspiracy that was forming and being reported back to me, when it was actually so far from the truth. I was gobsmacked. I've been doing what I do for nearly 20 years, and I pride myself on transparency and running a tight ship.

 

You have discovered exactly what many of us have had the misfortune of discovering with Matthew. I am also privy to the disgusting behaviour shown towards Dave, and I am sorry for him that he is now on the receiving end of Matthew's vitriol.

 

Without rambling, apology accepted and thank you.

I read this thread again last night and on further reflection....

Really marc you've been doing this for 20 years ?? You mean you've been doing this for 20 years until you got caught out !! And the result is ?? Another local aussie industry that is essentially on life support whilst the imports flourish as usual and the locals are left fighting amongst themselves over the ever shrinking market share that is left to them. I hope your new found lifestyle and your imported trinnov was worth it mate Or better still try and do what I did and design and manufacture a sophisticated audio product from scratch whilst NOT being paid a single cent to do so, and see how much harder it is than sitting in front of some forum software all day pushing the delete key ! It may actually give you a better appreciation of the difficulties involved with trying to do that here in this country with people like yourself undermining their efforts before they have even got off the ground

Unlike OzHifi.net which doesn't censor out links to stereonet if it is of interest and we don't restrict what you can put in your signature either

[At 48 KHz Total Tap count = 16384 tapsAt 96 KHz Total Tap Count = 8192 tapsAt 192 KHz Total Tap Count = 4096 taps]

When designing FIR filters it is important to note the limitations of the DSP in handling the filter. The tap count of the DSP is dependent on the clock rate of the DSP and the number of clocks needed to perform a multiply accumulate (MAC).

For the ADSP-21489 SHARC used on the UP the DSP is clocked at 392MHz since it is syncro-locked to the master clock of 49.152MHz and not an asynchronous 400MHz clock as used in most designs.

Since the SHARC can achieve two Multiply-Accumulates (MACS) in one clock cycle because of the SIMD capability the SHARC is capable of 786 MMACS. To get the tap count per sample clock divide 786432000 by the sample rate. For example:-

At 48 KHz Total Tap count = 16384 taps
At 96 KHz Total Tap Count = 8192 taps
At 192 KHz Total Tap Count = 4096 taps

These are the theoretical maximum tap counts for a given sample rate and then you need to divide that amongst the number of filters used. However Audioweaver has another trick up its sleeve to expand the tap capability by down sampling to a much lower sample rate which would be appropriate when building a filter to process low frequency information for a woofer etc. For example if you are only interested in processing bass then you could theoretically down sample from 192KHz to 3Khz which would expand the tap capability by 64 times from 4096 to 2621444 taps. Once you have done all of the processing at 3kHz then you up sample back to 192kHz !

If you need huge tap count at the native sample rate then the UPP is the way to go by offloading the DSP duties onto external PC hardware. See here for more info https://analog-precision.com/forum/wiki-and-qa/extending-the-dsp-capability-of-the-ultimate-preamplifier-plus/

Hi Sunny

I suggest you start with the example templates for crossovers in the threads above this one and just modify them for your needs.

For better understand on how to upload scripts to the Preamp please start here.

Stereonet disables any URL to What-Hifi so we have enabled it here LOL

This might explain it

Has anyone noted where Andythiing started the thread?

It has now been bolted onto another obscure thread to stop Stereonet users from finding it.

Just for reference if you cannot find it on Stereonet forum here is the link

https://www.stereonet.com/forums/topic/579155-sydney-hifi-show-2023/

It wasn't deleted but just moved to some obscure location on his forum so nobody could find it easily and there was only one post with a link to the official show website but it still doesn't work

Come on guys wake up will you !! Hifi community - sure it is LOL

Rushton has bought a RADAR to detect members who don't comply with his rules. It's all about shutting down the Willsenton thread that has over 300 pages as its detracting from his paying sponsors. This must be killing him that this amplifier has gained the audience it has, ALL FOR FREE. I hope people keep it up.

 [attachment id=1 msg=615]

Stereonet should be renamed "Willsenton Audio". The brand doesn't even appear in the brands list but doesn't have too. They got 300 or more pages of free plugs and advertising which is unprecedented for a forum that heavily polices self promotion of any local brand.

Ironically there is a review of the Audio Research i/50 integrated valve amp on the same forum which is pretty much a similar product to the Willsenton Audio except it sells for $10k vs $1500 for the Willsenton Audio. For the price Audio Research are charging for the phono preamp option alone you can have one Willsenton Audio integrated amp ! Go figure.

Once the chinese start making these products it then becomes a race to the bottom which is why I am hesitant to get involved at this level anymore and focusing my efforts elsewhere. I have seen it happen with DAC's, preamps, amps, DSP etc

It's too bad that he killed off the local industry by pitting one vendor against another and watching them fall like dominoes. They all but died under his watch and he thought he was on the gravy train with his advertising bureau plugging selected imported brands and now the chinaman is stealing away market share of those brands by stealth and right under his nose too. It's a case of what goes around comes around

cheers
david

I must have predicted this. Audio Research now in receivership. Once the chinese got involved in valve amps it then became a race to the bottom. $9000 ARC integrated amp vs $1500 Willsenton Audio integrated amp. It didn't take a rocket scientist to predict who was going to win this race ??

It would appear that in the past week in the State of Minnesota District Court, County of Hennepin Fourth Judicial District, the Audio Research Company has assigned its debts and assets (sic) to the Lightwave Management Group in Minnesota. They specialize in turnaround/bankruptcy and financial crisis management.

Interesting that these papers were filed just about a week after AXPONA 2023 was over.

https://www.whatsbestforum.com/threads/whither-audio-research.36751/

I reviewed the Assignment filed on April 4 in state court. Audio Research voluntarily agreed to assign all of its assets to a receiver, Lighthouse Management Group, Inc. Lighthouse Management is in the business of working with troubled businesses and regularly acts as a receiver. This process is an alternative to a bankruptcy filing in federal bankruptcy court; however, any three creditors can seek to place Audio Research into an involuntary Chapter 7 bankruptcy in federal bankruptcy court. This might occur if three creditors do not trust the process or the company's strategy in state court. Schedule B attached to the Assignment is 31-page, single-spaced list of creditors which includes many familiar names in the audio industry. The job of the receiver is to liquidate the assigned assets, collect all proceeds, pursue any claims, pay and discharge all expenses of the liquidation, and then pay and discharge (to the extent of available funds) all debts and liabilities of Audio Research. Sufficient funds may or may not be available depending on the sale proceeds and the amount of the debt. Unlike a bankruptcy filing, there is no statement of the amount of the debt in the state court filing.

The receiver has complete control and power of attorney over the assets of Audio Research. It is likely that, to maximize proceeds, the receiver will seek to sell the entirety of the assets and business (including goodwill) as a going concern; if that effort is successful, the business may continue under the ownership of the buyer. It is also possible that Audio Research already has a transaction agreed upon in place for the sale of its assets and business (including goodwill) as a going concern to a “white knight� and the filing with state court is intended to facilitate that transaction without an involuntary bankruptcy filing. I expect that Audio Research has already been (or soon will be) communicating with creditors. The argument will be that the “white knight� buyer will only contribute funds if Audio Research is not forced into bankruptcy and a bankruptcy will yield far less value for creditors.

Well it makes a total mockery of him asking the punters to remove their URL from their signature. I can go onto diyaudio, ASR, WBF etc and put a URL in my signature anytime and nobody barks up about it except for the poodle here

Unless objective measurements are made with proper test equipment all of these reviews will be nothing more than a white wash using lots of flowery language and cliches that will never show up any flaws in any equipment they review and I bet you won't find one negative review that stereonet has ever done simply because they only ever review sponsors equipment. They don't randomly take gear off the street like ASR does and then review it with no strings attached so it's a bit like the pot calling the kettle black when they start criticizing other reviewers for doing exactly the same thing they do. In other words those types of reviews are nothing more than glorified adverts.

I spoke to soon. Stereonet has allowed the post to stay now !! Must be reading this thread

Willsenton Audio The gift that keeps on giving back to itself courtesy of stereonet !

Congratulations to Willsenton audio for reaching 400 pages of free forum advertising and over 10,000 replies to date, all courtesy of stereonet. That should have added significantly to their bottom line and nothing to stereonets for all of the sales of their tube amps. Even though Willsenton Audio is not a sponsor of stereonet and doesn't even feature in their brands listings we believe that Willsenton Audio should be awarded with a stereonet Applause Award for their outstanding contribution to the Chinese economy and reaching the 400 page milestone without contributing or spending a single cent in Australia with stereonet !!

We'd hate to think how many Chinese made amps have been sold and sales lost from the local sponsors because of this thread. Maybe one or two for each page of the thread at the very least
We would like to offer Willsenton Audio an unofficial stereonet Applause Award for all of their efforts and sponsorship to the stereonet “community� to date which just happens to be zilch !

Too bad if you are a local tube amp manufacturer and I know there are still some left here in Oz but don't be dissuaded by this apparent double standard. It's what stereonet are good at doing. Destroying what's left of the industry in this country and stacking the scales in favour of yet more imports. And make sure you remove your website URL from your signature because we wouldn't want you to have an unfair advantage over the paying sponsors would we. On behalf of all of the local aussie hifi manufacturers left thanks again stereonet for nothing
