Attempting to reach Amir to submit gear for review

[waxcorp]

Hi all, first time posting - been really enjoying learning so much from the forum over the years!

I was able to pick up some reference “Ultra Pure Oscillator” devices (better than -140dB THD) from Janascard and would be happy to submit at least the 1khz version to @amirm for review. The others are 10khz and 99hz (he wouldn’t build a 100hz because the 50hz mains harmonic apparently makes it challenging to test in the EU.)

I’m having trouble getting through the spam filter when attempting to use the “start conversation” feature that I saw Amir recommend for this type of communication. Maybe it’s because I’ve never posted here, not sure.

Any help getting in touch would be much appreciated!

Kind wishes,
Josh

@amirm this guy wants to chat you ^^^.

Sorry about that. Until you have 15 messages, our spam filters will check your messages and often create false positives. Please use the Contact Us link below and email me and we can take it from there.

I would love to test that oscillator. By the time i went looking for it, the designer was no longer making them.

Thanks for the super fast responses! Forgot to mention that I had also tried the Contact Us method and that failed similarly. Just tried again and again it gave me this response presumably due to the same filter on Start Concersation (attached screenshot). Feel free to directly obtain my email from my private user profile info and send me a note that way if possible.

Best,
Josh

Oh, I didn't know those messages got filtered as well. I will send you an email.....

Dear Amir,

Thank you for your wonderful contributions to society via this invaluable service. I have exponentially grown to admire the egalitarianism in your objective approach.

I recently completed a 60G installation that outperformed all my previous work, ranging from 400G to 2.34M. This installation included the Revox G1 center channel, which has an elevated tweeter. I suspect the design might be a 2.5-way system, as it subjectively sounds phenomenal. Could I have Rutherford Audio send you one for measurements?

Additionally, if you ever reconsider measuring the Elipson Planet L, remember that with 14 of those speakers in a room, they not only serve as speakers but also act as diffusers.

Is there a way to measure the scattering properties by frequency with the Klippel of such a dual-purpose device? I am happy to re-offer these to you, and there is no need to return them as they are shinny white and I replaced with Satin. I believe there was even a movie made about it...

In all seriousness as the world moves to multichannel this design becomes very useful I humbly reassert this brand should be measured, they are looking to open a distributor in America so it will be possible to buy/sell them over here.

Best regards,
Peter

Sure, as long as they are still in production, I am game testing them.

And yes, I show the dispersion per frequency already in directivity and beam width graphs.

Thanks for the kind words as well.

I will send them on Monday by UPS. My email is [email protected]. I will also arrange for Robb of Rutherford Audio to send you the Revox.

To clarify, the graphic above represents the scattering of a barrel diffuser. I was wondering if a similar measurement could be performed on spherical speakers using the same apparatus when one speaker is aimed at the round back of another. I am considering this for room acoustic design, incorporating diffusive data from 14 or more speakers into the room modeling. This second set of measurements would treat the speaker as a diffuser, extending beyond the traditional CEA 2034 standards you have mastered.

On it's way in the afternoon today. Have fun!

Sorry this shipment has taken so long Amir.
