There is a lot of propaganda in that video so tread lightly. There seems to be a concerted effort to claim Auro upmixing superiority since its failed as a native format. I did some 2CH upmixing tests last night between the DSU, DTS:X and Auro 3D and all the Auro folk, including Wilfred and...

Yea it's fine, though still not SOTA but not bad. I don't use the DAC for the front LCR's since I have the separate Marani DSP running for the active speaker setup.

You're right and that measurement looks worse than it really is. Someone send me a link to Amir's commentary about this and I looked over my other measurements I didn't publish. What this graph is actually showing is a combination of the down-sampling behaviour, anti-aliasing filters and the...

I had to help my daughter multiplying/dividing and simplifying exponents tonight. It's amazing how much you forget when you don't use it. Believe me, calculators like Peng linked to, I use all the time.

I did some 2CH upmixing comparisons with the front LCR's turned off on my Storm Audio ISP MK2 processor last night and got interesting results. Check out my YT Video here: If anyone has all 3 formats, please recreate this experiment using Dominque Fils-Aime track Birds. DSU - best layering...

Don't be lazy, know the math ;)

So if you look at the RMS level on the vertical scale for this measurement, it's around 5.6dbV. To convert dBv to Volts(rms) you do alog(dbV/20) which in this case would be alog (5.6/20) or 1.9Vrms.

Not yet. Writing up my bench test report first then testing YPAO next,.

I think the build quality and parts used on the Yamaha are mostly top notch. I just think its a combination of bad software development and perhaps not properly vetting the design before releasing. The did use lower grade dacs on some of the channels and perhaps they also used different VC ICs...

I had the equivalent inwall model of the Studio 20 V5 in the guest room of my old place. They were incredibly well crafted with excellent build quality. I did find them a bit bright. In comparison, the 800F are the most tonally neutral speakers I've ever heard from Paradigm. To answer your...

That's true but it's also the only room correction system that virtually does nothing so there's that ;)

Channel 4 is the subwoofer channel and out of this test since it was done at 1kHz. Just ignore. I added a note in the review for clarity.

That Loosechange guy is a bit nutty. He prays to his Audioquest cables every night and rumor has it he takes some of them to bed with him too ;)

I have 9 bed channels, 4 height channels and 2 sub channels so I'm only using 15 channels total. Eventually IF Storm gets FIR, I will bypass the Marani and do my FIR correction as triamped speakers for the front LRs and center so that will up my channel count to 20. Also, I can repurpose the...

Those are completely inaudible #s and the whole SINAD thing puts people out of touch with that fact. Nobody uses SINAD to show performance other than ASR but I included it here so people could make Apples to Apples comparisons. There is no magic to representing distortion as dB instead of...

Folks; As many of you know, I spent the last year testing and evaluating the StormAudio ISP MK2 24CH AV Processor. My beginning journey revealed some performance issues that I worked closely with the engineers at StormAudio to improve upon and they did so quite excellently. When I set out to...

Nice review. How about adding some product pics to spruce it up?

Here is more on breadcrumbs: https://www.searchenginejournal.com/ranking-factors/breadcrumb-navigation/#close As for the "Preview" date instead of "Review" date, that's F'ing brilliant! I will see if its possible with my web admin. Thanks for the suggestion.
