Trinity Audio Engineering - What the future holds
Feb 19, 2017 at 5:09 PM Post #1,321 of 2,949
  While I'm waiting for my Trinity Air & Hunters to arrive I was web searching headphone reviews (as we do) & came across a new US start-up called www.periodicaudio.com 
 
Can't seem to find anything about them on here, but read an interesting post (on a site called audiosciencereview) from one of the owners, Dan Wiggins, which I found very informational. Sounds like he knows his stuff! Here it is:-
 
"Well, after the Beats explosion (I did some consulting for a big name at that time), nearly every factory in China became "a headphone factory". And suddenly you had dozens, then hundreds, then thousands of brands popping up, selling off-the-shelf product from China.

The big German brands - Sennheiser and AKG - kept plugging along. Bose kept going with ANC specific units. And everyone else tried to focus on consumer products. Everyone wanted to be the next Beats (and truthfully, no one will be. Beats was a unique combination of the re-emergence of the sports-star/music-star glamour with the ubiquity of portable music players/phones to carry decent amounts of music. It was a generational shift in consumer behavior and Beats captured the essence of the behavior).

Now, it's all about marketing - how do you pitch what you have, how to do you tweak an off-the-shelf design. No slam, but a lot of the current darling of high-end over-the-ear headphones started by taking off-the-shelf Foster units and changing out earpads, or headbands, or maybe rear cups. Some move up to doing more - like walking the sample rooms at Foster (which are impressive, especially the Panyu, Guangzhou, China facility to which I've been way too many times), choose a stock transducer, and go for a new industrial design.

And as more and more 2nd and 3rd tier companies are making product in China, they will cover your costs on mechanical design, they will do prototypes for you for free, and lower MOQs to hundreds. So suddenly if you fancy yourself a "headphone designer", you can get into the business for $10,000 and some effort and have a stock of units. And probably - like 99% of those in the market - end up selling dozens a year (or less). So you get a proliferation of brands big (remember SOL Republic?) and small (look at dozens that come and go from one show to the next).

It's really a super-low barrier-to-entry to the market, but to build staying power, to actually succeed long-term, takes more than just a slick marketing gimmick and cheap product (and trust me - you can get off-the-shelf product for really cheap - like planar magnetic headphones for under $40/pr, decent 40mm diameter over-the-ear units for under $20, and OK sounding IEMs for under $5/pair). It's why you can find $4.99 earbuds at your local 7-11 store, and also see $50,000 new units. Heck, even big universities are getting into it, like the Warwick Audio 'stats that many are starting to roll (essentially rebranding an off-the-shelf design from a design team from the University of Warwick) for $5,000 a set. Change the cosmetics, give it a unique name - and presto, you're a headphone/IEM brand!

But as all things acoustical, the biggest effects are in the transducers. You can tweak earpads and headbands and rear cups, but you get relatively small changes in performance. Doing a unique driver - something fresh from the ground up - is where big gains are made. Rolling your own transducer takes real engineering chops, some advanced modeling, and lots of sweat. Not many people do this - really, it's AKG (Harman), Sennheiser, Bose (a little), Foster (who designs/builds for LOTS of big names), and then a handful of independent designers/engineers (such as myself). Many of those smaller Chinese factories will "design" their own transducers, but it's usually just taking a well-reviewed product, taking it apart, and cloning the insides as best they can.

I've spent a few decades designing transducers for nearly everyone in the business (I can guarantee my work has been heard, at this time, by everyone in the world - either directly with products like SONOS and Beats and Final, or indirectly via pro work like KRK and Mackie and Event or consumer products by Dell, HP, Apple, or generics from Flextronics and others) and worked with my Periodic partners to do something special. TO do what we have done for dozens of other companies in the past. We wanted to step forward and see if we could do what our clients have done.

Rolling a product from the ground up means more time and effort and more cash, but the results are better. So we started with a clean sheet and went full-focus on the product. Three products, the best we can realize as a platform, and just do sonic changes with the materials chosen. Nothing else. It took us 4 months to realize, but after the time and effort and tooling (which we did not have to remake/redo - we got it right the first time), we came out with something we believe is unique, in terms of performance, price, and positioning. We didn't do the "in thing" which is handfuls of balanced armatures jammed together in a too-small housing, with too-complicated networks. We did what we thought was right - and I think it's going to pay off. The results at least seem to be drawing lots of attraction!"

Be really interested in anyone's views, maybe by PM preferably, as I don't want to go off Trinity message any more than I just have.


I got a chance to meet this individual and try out his two models...  A 100$ model and a beryllium Dynamic Driver that cost 300$ I believe.  He was very nice and did talk about his extensive experience in working for other companies and trying to go at it on his own...  They were single dynamic drivers so they didn't quite have the detail that a BA can, but they had more warmth through the entirety of the sound signature.  The only Dynamic Driver I have tried that really surpasses the BA is the campfire audio Vega, but there's a price tag for that achievement. 
 
But both those models are big on the single driver design, which allows them to have some of the best cohesiveness I have heard for the price and their sound design is some of the best balancing of the overall signature I have heard.  They are not the best on detail...  obviously that's where the BA usage does have it's advantages especially at this price range, but if you want a single driver dynamic design that optimizes the advantages of having a single driver, the warmth of a dynamic drive, and engineered with a sound that is very well balanced, these guys do stand out at both prices, with the 300$ model standing out.  It does stand out among the crowd in unique way because of these characteristics....  and to tie it back in with trinity and comparisons...
 
It is a different sound from trinity...  and for the reasons discussed above...  As far as competing with them... absolutely...  the 100$ model competes with models of trinity at the same price and does have better balance and cohesion than most of their models, but does lack the detail those BA's have, but the periodic audio still brings good detail and in a warm less synthetic fashion than the phantom lineup...  But I still liked the Delta VII over the 100$ periodic model.
 
It's almost hard to say that the two companies compete straight up with each other because they are such different sounds....  You have trinity's hybrid IEM"s for the most part versus single DD's of periodic Audio...  They complement each other if you have both....
 
But the balance of the periodic audio's overall sound signatures is what makes them stand out.
 
Personally, I still love the Delta sound and the implementation of the drivers to make that sound signature.  The beryllium driver of the periodic audio is really good though and does stand out.

I just noticed the description for the master now says:
 
"Each earpiece is fitted with twin dual coil dynamic drivers in a out of phase configuration to create immense detail and smoothness along with reduced distortion and high resolution audio with added sparkle and midrange from our 2nd generation balanced armature."
 
Does this mean it now only has one BA? I thought it was going to be 2 dynamic driver in push pull and 2 BA configuration just like the PM4 was, but according to the new description looks like it will be a 2 DD + 1 BA. Since I placed my pre-order, these seem to have gone from stainless steel CNC machined 2 DD + 2 BA IEMs to pot metal 2 DD + 1 BA IEMs, which would be a significant downgrade in quality and value.

It says:

"Incorporating our new dual coil dynamic drivers with 2 dual balanced armatures." "The dual balanced armatures provide extra sparkle, detail and precision that dynamic drivers can't achieve on their own"

1. That is two dynamic drivers
2. 2 dual balanced armatures

I don't ready anything wrong. It's still 4 BA and two Dynamic drivers.

Are your referring to the PM6? I was talking about the Master (replacement for PM4).

Ugh. Yes I was sorry, but the Master is still supposed to be the same as the PM6 just two drivers less. So 2 Dynamic and 2 BA.


Yes but the description of the master on the website says "2nd generation balanced armature," not armatures, which implies there is only one BA. I was wondering if this was a change to the design or just a poorly worded description on the website.

What got changed is better drivers is all. I saw that too. It's just bad English. :D The guy who has his mouth open and screaming is probably who wrote it. Hahaha He looks like he would have bad English.
