The name is familiar. It’s not new. What do Prana distribute?

@idler-21st can you explain what went wrong? |
Hi All, I'm the owner of Prana Distribution. Idler-21st, (who began this thread) is the owner of an idler turntable company called Semper Sonus based in Portugal. He's a very talented engineer who makes a very interesting turntable. During the pandemic we did something we have never done. We ordered a product without first auditioning it. We ordered 4 of these tables out of excitement for an idler table that was engineered from the ground up (not based on a vintage table) that was also somewhat attainable. (it can be had, with an arm for around $10k) We're still excited about it. We do have some internal issues to work out with Paolo over the coming weeks which will hopefully quell the need to air our business frustrations in a public forum. I understand his frustration and anger and likely feeling as though this was his only recourse. I hope to amend that premise. We've been in business in one form or another for 14 plus years. We've managed to maintain good relationships with many manufacturers for most of those years. I want to publicly apologize to Paolo for not being a better communicator where this instance was concerned. I hope you take a look at his table. They're really quite something. We don't have them on our website yet, (I wanted to sort some things out with Paolo first) but you can find them here We do have them in stock. |
Regarding our addresses. Our LLC is listed at an office in Cambridge. Something that was common practice in my previous professional life, which I just kept up. We have retail square footage in Gloucester, MA and in Medford, MA...both by appointment only. There is another local site slated for 2024. |
Well, that was interesting. Good luck to all parties. Question to @idler-21st - surely the point of an idler drive is to provide as much torque as possible to give it that idler drive?
|
Not as much torque as possible. You want enough torque to keep the speed constant, regardless of load variations. However, having that, there’s no point in feeding more torque, it would only potentially create additional vibration or noise. So, speed is monitored several hundreds of time / second, and when a speed deviation is found, more (or less) torque is applied. It’s important to note that this kind of speed control is very different from the crude systems employed by manufacturers in the 80’s ("Quartz control" do you remember ?). Algorithms are now much more sophisticated (courtesy of the tremendous computing power available today), and they try to "approach" the correct speed smoothly, without over or under-shooting.

Well I would never buy a Semper Sonus. Why would anyone want a turntable that whenever there is an issue the manufacturer goes on a public forum to cast aspersions - airing his dirty laundry in public so to speak. Best to avoid issues like this - buy a different turntable - plenty out there without the aggro. I also note that one member on this forum who purchased this turntable had multiple build quality issues and ultimately sent it back -

Dear Idler, You did write, "Well, guess my due dilligence wasn't that good... Be warned !" Need I point out that those words go beyond wondering whether anyone had prior experience with the company? Anyway, I hope this all has a happy ending for you and Prana. Looks like you have an interesting turntable there to which I am favorably disposed as a Lenco fan, vertical idler wheel and all. |
You moniker is misleading. Your turntable is not an idler drive. An idler turntable is when you have an idler wheel between the motor pulley and platter ( hence the name "idler" ).
|
Yes, not an idler wheel in sight ! But there’s no misleading blurb in the website:
What I set out to do was to imagine what an idler could be like today, freed from the limitations of 60 years ago. And today you don’t really need an idler. Now you can get a motor to run at 150rpm, smoothly, silently, cheaply enough and you can switch speeds electronically. In the 60’s you couldn’t have that (at least in a consumer product), hence the need for an idler wheel and the added mechanical complexity.
|
You obviously have no idea how idler turntables work. The pulley size determines the speed of the platter - the idler wheels are just a transfer function - you can run any size idler wheel and the speed doesn't change. The idler wheel really is a low pass filter to reduce noise transfer from motor to platter. It has nothing to do with motor speed or platter speed. I'm staggered at your lack of knowledge. |
@idler-21st So why does it say this on the website? SEMPERSONUS TE2EPICYCLIC IDLER DRIVE TURNTABLE |
It says idler here: https://www.atelier13-usa.com/sempersonus-te2-idler-drive-turntable Not sure what that site is. It’s a link in the @audioprana post above. Looks like it is not in your site. |
Okay lets not drag Constantine at Atelier 13 through the mud. He is a first class guy and @audioprana should have just linked to @idler-21st website. I am going to say this is that I would not buy a thing from either of these two companies. Clearly @audioprana was looking to clear their name and @idler-21st should have been more discreet and contacted them direct. Not questioning ethics and integrity just class and dignity at this point with these two. I have personal experience with Constantine at Atelier 13 and I can attest to his ethics, integrity, class, dignity and knowledge. He has my utmost respect and I have dealt with a lot audio companies through the years. He is one of three that I continue to deal with.
