I can talk and write about it for pages but this subject is not recognized as “audio”
generally, unfortunately…. [/quote]
Don't know about the others but I would be very interested to learn those tho...

I think they were the 1st: https://aer-loudspeakers.com/aer-pnoe/

Possibly the deepest thought I've come across as to why pursue audio (or actually any other activity). All that we need is in us, we just need to discover it. Fantastic, thank you very much Romy for sharing it.
Cheers,

Anthony, thank you for the explanations. For some reasons you mention, I use C-cores. Loose coupling (pri and sec on the different legs), controlled gap and low emission. BTW toroids do have some "distributed gap" but it's small and uncontrollabl...
|
Congratulations on the build!
[quote user="anthony"] Yours uses all toroids, or mostly so, which are more efficient than the EI that I use.

Why have you chosen EI vs toroids? The latter emit less.

How heavy is the structure to be suspended?...
|
As a practitioner of vibration decoupling (stacore.pl), I second the idea. No gel, foam, rubber, etc will work on ULF as high mass + pneumatic mounts do. Pref. pneumatic damped too. I can assist with the design of the suspension. Cheers,Jarek...

Paul, its all welded and filled with non-dissolvable epoxy. I've convinced Kilian to try to get the cart as close to the optimal technical specs ass possible. Let's see how much he will be able to do. Stich asked for s/n perhaps he can trace w...
|
My FR7f has been examined by a Dutch master and the cart is f*cked up thoroughly:
-boron cantilever glued angled with non-solvable epoxy resin
-high tracking dist even when azimuth rotated - someone tried to manipulate the gen...
|
But I'm not an imaging or a soundstage freak. I'm looking for a cart specialist in EU to try to correct the geometry. Any reasonable suggestions welcome.
Thanks,
Jarek

Well, I've heard from one AF1 user some less than a neutral feedback. He was also reporting on one more user not 100% satisfied with the table.
Hence asking.
Cheers,

Paul, not sure if you are familiar with the combo. There is nothing one can adjust apart from VTF, VTA and P2S. Even with the latter I'm bound by the EMT930 arm hole. Smart collar design by my business partner gave me some +/-1.8mm ...
|
[quote user="Paul S"]Didn't read it yet, but I will say I never noticed any problems with the AF1[/quote]Paul, do you own one?...
|
Today I continued exploration despite the azimuth problem which starts to look serious (either the arm or the cart has a problem and no az adjustment, researching this). Added some VTF to reach 2.70g to give it a bit better tracking conditions despit...
|
Paul, thank you but it's of no use. Pls look at the FR combo. The only thing I can do is P2S. To set it correctly the best is laser engraved arc on a mirror surface - waiting for one. And I have a copy of the Dennesen too. But the big problem is ...
|
Fi-analy started listening the FR combo! The setup is somewhat haphazard:* P2S unknown - trying to get 231.5mm recommended by the Germans, took the pains and the cost to design and make a special collar but missing a laser engraved protractor to see ...

t took me 5 freaking years to fin-anally install a second set of SUT's in my EAR834. 4 out of those 5 years was waiting for Tribiute Pieter to make me custom silver SUT's on nanocrystaline core. I even found him the wire. I went boutique and the ...

You may take a look at GU-80. It's a DHP but some report excellent sound.
I had some ideas regarding it:

Hi Paul,WTF is probably the right question. The time has been the problem - in the past 2,5yrs Ive set up my own audio company and only recently came back to working on the front end of my system.I changed the concept and bought the FR64S arm togethe...
|
I must be somehow unlucky here. I recently added a US cleaner from Audiorevita +DIOY 1micron filtering. I use Rushton's recipe with 5% IPA +0.13% Photoflo + Deionezed water, 15mins, 35C, 1.5" spacing, 60% power@40kHz, 3rpm (yes, the motor is quite fa...
|
Not a MS owner, but have been wondering why buying this 30+ yrs old mat at all with all the risks you describe? Virtually any modern metal shop will be able to machine it and check the flatness down to microns. The price I guess would also be much lo...

Big power installations use big screws. M4 or M5 will not reliably tighten - the thread is to small, will not bite into the copper enough IMHO. So I went with brass. If chasing conductivity, why not silver than?Cheers,N-set...
|
Unless they process it somehow (cry?). I was going to order copper bus bars from a machinist friend but I realized copper as it is is way too soft for reliable screwed cable connections.M4 or M5 screws hosted in copper will not stand much torque and ...

Thanks! And who is winding your signal iron? Pieter?...

Gentlemen, I can only hope to be wrong on the air-borne feedback.Actually your project Anthony made me think of coming back to my Staxquiades project - a Milq inspired monster amp for my Stax headphones. Do you have a source of big PSU Nichicons at ...
|
Anthony, irrespectively of all the extreme acrobatics you are doing with the inner damping and the structural isolation, sound wave hitting your tubescan multiply all your work by zero. As simple as that. Big tubes = big inner structure structure = l...
|
Anthony, I'm sure you realize that air springs and bearings can only isolate from the structure born vibrations. Placing the tubes so close to the speakers you give them a great chance to catch strong airborne vibrations. Or will they be shadowed by ...
|
Ah ok, these are just the results. I forgot about this post :D...
|
but would correct that this forgetting time can be shorter than 12 weeks in some human specimens (like me)...
|
[quote user="anthony"]Hi Jarek,It was your thread on here that prompted me to think about incorporating the vibroisolation into the amplifer. Although not seen, I have also designed in some ball bearing horizontal isolation that sits on top of the p...
