This is a review and detailed measurements of the Trinnov Altitude 16 AV Processor. I received one sample from a kind member after which Trinnov also contacted me and sent me another with an improvement (see below). The Altitude costs US $17,000.
In contacting me Trinnov expressed that they had made an optimization to the DAC that resulted in better measured performance but not audibly. For this reason, they have not promoted this change. They plan to make a more substantial revision of the DAC to come out later that they will offer as upgrade to current customers. They have asked me if I would participate in testing that and of course I said yes.
The Altitude 16 does a great job of hiding the fact that it is built on a PC architecture with a beautiful front panel and controls just like any "appliance" version of the same:

The display has a very high resolution and elegant look that I liked. It is a bit to fully refresh but the interface was responsive. On start up there is a faint fan noise but it goes away once it boots. The back panel shows all the balanced I/O you would expect in a high-end AV Processor:

Now you can tell its PC guts given the standard I/O panel on bottom left. But again, you don't really notice that there is a PC in there.
The measurements you are about to see were reviewed by the company and were agreed upon as being representative. On that note, the company was exceptionally nice to work with and brought a constructive attitude which I much appreciated. Support is a big deal for such expensive purchases and it is good to see it be available from Trinnov.
Trinnov Altitude 16 Measurements (DAC)
As usual, our focus is the hygiene of the basic audio pipeline in these AV products. We feed it a digital signal and turn off all effects and processing and see what the DAC is capable of doing compared to other AV products (and desktop DACs):

As usual, I adjust the output to 4 volts which is the standard for desktop/stereo DACs (over balanced output). Performance here is competent and inline with other better AV processors I have tested:

Hopefully in the future we get performance in "blue" region of our performance buckets.
Sweeping the input we see that performance gets to where we measured and stays there for good bit until it clips above 6 volts:

Dynamic range is good:

DAC filter showed a strange but minor kink:

Trinnov has figured out the cause of this and is working on a fix. It was not important enough for me to hold up the review.
For the rest of these tests I used Toslink input as HDMI out of my measurement computer truncates to 16 bit. Let's start with IMD:

Here is our jitter test on both Toslink and HDMI:

Both show room for improvement although in the case of jitter it is not an audible concern due to very low levels that are below threshold of human hearing.
Linearity shows some inaccuracy:

So we get the magical 18 bits again.
Here is our THD+N versus frequency:

I could not run my multitone test because it has a 192 kHz sampling and Trinnov Altitude 16 is not able to play anything above 96 kHz. You have to move up to Altitude 32 to get the processing power it needs for that.
We have been waiting a long time to test any Trinnov processor as it is considered the pinnacle of high-end AV processors. It was great that it came to pass and I did not find anything broken in there. We have our answer that high-end AV processors as they exist today do not bring better measured performance in their basic DAC pipeline. Good news is that Trinnov is among just a couple of companies that has promised new generation of DACs to provide better performance. And that our testing has motivated that.
On the strength of excellent company support, future direction and good measurements, I am going to put the Trinnov Altitude 16 on my recommended list.
Time permitting, I plan to test the Room Optimizer in there which is the main reason behind the strong reputation of Trinnov processors.
As always, questions, comments, recommendations, etc. are welcome.

Not sure exactly what you mean by "processing performance" but if you mean processing features then there is a lot like ability to array speakers, extensive active crossover and eq functionality, many more speaker layout configuration options, etc.. Then beyond processing the is the much more sophisticated room correction and an upgradable architecture that means (especially in the case of the Altitude 32) that it is still one of the most advanced processor after almost 8 years. If you bought on of the first run processors you still have a processor that is up to date with the only real thing that might need to be updated occasionally is the HDMI board.Do we think though, for the price and the money we should have better performance? Because to be fair, how close is the Denon x8500h in terms of processing performance at 3 times cheaper?
Well I recently upgraded from a Denon A-110 to the Altitude 16. One of the major reasons was the Denon and most all other AVRs using room correction software have to down sample inbound sample rates to 48hz to handle all the simultaneous processing. The trinnov, being a software based computer, does not. If it gets an inbound 24/96 it plays it back at 24/96-not 48. That is unsettling for the majority of people demanding hi-res 24/192 sample rates but using Audyssey and Dirac. (I was one of those, and I didn’t know.) I don’t know about room perfect—perhaps it is like the trinnov or not.Do we think though, for the price and the money we should have better performance? Because to be fair, how close is the Denon x8500h in terms of processing performance at 3 times cheaper?

Of course there are use cases where another processor might be a better fit. For example I went with a StormAudio because of its ability to do 32 digital channels out and multiform capabilities but could easily have gone with the Alt32. It was a close thing.
Before that I had a Denon 6300 (Anthem & Onkyo before that) and can say there is no comparison from a processing, configuration flexibility and upgradability perspective.
Of course nothing wrong with any of the big box brands if all you want is something you can have setup in a few minutes and happy to have surround sound with maybe a run of a autoroom correction that might improve things a bit.
Nothing like putting words in a persons mouth.Did you notice a sound quality increase switching from the Denon to the Trinnov? Denon's, generally measure well, so how does it sound? Smoother? Cleaner
I bought the StormAudio not Trinnov. From a sound quality perspective the biggest difference going from using the Denon as a prepro to the StormAudio audio was another more hiss coming from the speakers.Did you notice a sound quality increase switching from the Denon to the Trinnov?

Yes, connected to power amps via q-sys core. Guess biggest difference is Denon is unbalanced out and StormAudio is balanced out. That was when I was running analogue out. Now I run digital out (AES/EBU) of StormAudio to q-sys core, so all the DA conversions occur in the core.Interesting, same power amp and speakers? Even my x4400h does not hiss unless vol is at >0 and ears within inches.
