Is a $5,500 professional Trinnov calibration objectively better than a knowledgeable DIY calibration?

From yesterday’s webinar - this was one thing, that pro calibrator would do for you in the past - do the finetuning and defeating default settings. Now with the options to do it in automated way and with claimed WF algo improvements for everybody - gap between pro and DIY will become even smaller.

I really don’t get this Trinnov position - I would like them to be much more welcoming to tweakers and enthusiasts and not create the perception “it is too complicated fo ryou guys”.

I posted on avsforum that I believe I can do just as good as a professional calibrator charging $5500. I never said professional calibration has no value, nor did I say anyone can do it themselves without any study.

A $5,500 two-day calibration can absolutely improve a system, particularly for an owner who lacks the knowledge, measurement equipment, time, or interest to do the work personally.
I would say that is probably 99% true, the 1% would be to allow for usual circumstances/conditions of use etc.
The disagreement started when another AVS member told me that by saying I could achieve results “just as good” myself, I was insulting highly trained professionals and that I would probably: “never know how good your system could potentially sound” without hiring one.
It is the internet, so that kind of posts are expected, especially on the very popular AVSF where numerous posts in one thread is not unusual.
That eventually resulted in a well-known professional calibrator, Adam Pelz, whom does training and beta testing for Trinnov, is a Trinnov dealer, owns Bespoke Cinemas per his linked-in, sending me several unsolicited PM's describing his service.
Two days? That's fine for users who does not have the knowledge and time to learn, let alone post calibration experimental tweaks, and verifications by measuring, and those who mainly go by ears, not measurements so after paying $5,500 for a "professional", they would likely hear improvements, regardless.

Trinnov is obviously one of the most feature rich and inherently sophisticated RC/EQ package that I have no experience with, but I do know that I have spent many hours, in order of magnitude more than 48 hours (2 days/nights) on the much simpler Audyssey and Dirac Live, so even if that professional knows more than you and I, I am sure we can make up for it by learning and doing it ourselves, naturally, obviously, assuming we have the basic technical knowledge such as in advanced mathematics and science (physics) or engineering. I wonder what is the qualifications of this "professional", diy type, degreed, certified, other than what I could imagine in post#44, "....while studying engineering physics"..?

It is. However, they used to let DIY'ers take their training. I have no idea if that's still the case. I just find it funny that they call me a tweaker. I mean, I have multiple engineering degrees, I'm not a meth head. And yeah, I stay away from all dealers now days, that's actually how I became a tweaker in the first place. :D

It's their business model.
 
I will hire Adam for my next HT. He is the best out there and he is worth every $ you spend on him.
Best for what? If you mean home theater design and optimization for sound, definitely not the best out there. If you want the best, the names are Keith Yates and Tony Grimani. They would however, not touch small systems and certainly nothing you have put together yourself first before calling them. Everyone else is tier 2.

If you have 250k+ HT, it is a no brainer.
$250K??? If you are spending north of $100K, you must use the above mentioned names. They will professionally design and simulate your room prior to spending that kind of money. I would not use Adam in such a project. This is the kind of work you can get from Keith Yates on just the sub location and number simulation as he did for our demo home theater at Madrona before we moved:

I think I can get 90% out of the system by myself, but why should I leave anything on the table. This is valid for Trinnov.
You can't get within 90% of what keith and tony design by yourself. They are way outside of your means and capabilities.

Trinnov will solve problems with the system as it sits. Top designers prepare the room/equipment to be best optimized later -- manually or automatically through likes of Trinnov.

Really, if you need help, hire someone like Mathew Poes. He can give you advice and help you remotely. He won't ask you for $5,500 up front for some nebulous remote running of Trinnov. Don't throw money at folks because they are active on AVS and such.
 
No, these are forums that distinguish between public expression of opinion in an online forum and privately sent messages. Otherwise, a private message would lose all value and become public—and thus no longer private. It doesn’t matter whether the sender is a company or an individual, nor does it matter what the content is, unless it violates the forum rules or legal regulations.

I think it’s simply good etiquette to be able to rely on the fact that a private message remains private and isn’t made public.
The etiquette ends when the context is making money from a member. Then it is a sales transaction and there better not be any expectation of privacy. Why would you want to be disbarred from sharing communication from commercial entities this way? How are you or the society better served by providing such secrecy? Wouldn't the vendor be more ethical to you if they knew at any time you could share the communication in public?

Remember how many times you have heard that your communication with a customer service agent may be recorded and analyzed. That runs foul of your ethics, right? That your communication was only with that agent and not be shared with others. Yet it will be. For same reason, you have the right to share their communication with anyone you like.

All true statements, and also nobody was talking about hiring Adam for HT design. What I think one is hiring with someone like Adam, is superior ability and experience in critical listening and also full knowledge of Trinnov workflow [in very simplified way]. Adam is held in high regard also by few people, which opinions I respect. And re his cost - people pay more money to watch Taylor Swift dancing or to watch 22 millionaires chase ball for 90 minutes.

Just that you get the context - I had dedicated HT at our second residence [which happened to be in different country] - properly designed and based on Neumanns. At home I had 2Ch, We moved to our new primary house 1 week before first Covid lockdown - s I could not even visit second house for months and months, so I started to build “HT” at home. [and actually sold second residence at peak of covid induced real estate mass psychosis, probably double what I could get for it now]

So what I have now is actually 2CH with good bass system, and additional speakers and screen. Fun and Learning type of endeavor. Absolutely worth all the wasted money along the way [and there were quite some dead-ends]. Makes it easier to define, what I want and have more meaningful discussions with pros, as I approach design phase of new installation.

Had a chance to listen to Grimani designed theater and did not like it. Overall, I am not so enthusiastic about all those horns [krix, JBL to name a few] If anything then Ascendo, but this is then also completely different price proposition. I like line array/planar type of sound, so this is how I will go. What I am looking at is more MCH music optimized sound, not really movie performance as priority.

There are good guys here in Europe, that do excellent theaters and are one of the best DBA/SBA integrators, so I know who to reach and I am consulting them, while I do home purchase. They know ho work with specific architectural situations we have here, so I am covered.

Actually from US HT designers I have soft spot for Nyal Mellor - never had anything to do with him, but he was one of the authors of book re measurements and REW that opened my eyes.

Hi Amir,

I don’t see it quite as black and white.

I think there are plenty of shades of grey as well. Whether there are actually fifty, I don’t know – but there are certainly a few stages in between.

If a dealer or manufacturer contacts someone privately with a sales offer, sends promotional material, makes a specific offer, or otherwise approaches someone clearly and solely with a commercial intention, then I completely agree with you. In such a case, I would not assume that the communication deserves the same degree of confidentiality as a genuinely personal exchange.

But there are also many mixed situations in which the personal and the commercial can overlap.

Suppose I’m having a private conversation with Thorbjørn from @SigbergAudio about which driver he might use for one of his subwoofers. During the conversation we happen to get onto the subject of Oslo, I mention that I may have something to do there, and I invite him to dinner.

Or suppose I’m chatting with Keith from @Purité Audio because I’m in London and ask him what’s worth doing in his part of town. He then says: “Why don’t you stop by while you’re here and listen to some of the latest stuff? You can also compare GGNTKT directly with the AsciLab speakers.”

Or I’m talking to @Duke about a particular loudspeaker component, and during the conversation he tells me that I can buy it from him – or gives me some advice on where else I might be able to get it.

The same could apply to you. Suppose I ask you privately about good restaurants around Seattle, and because you know that I was once interested in the AsciLab speakers, you happen to mention that I could also stop by and listen to them while I’m there.

In all of these cases, there is ALSO a commercial element somewhere in the conversation. Even so, I would still regard the exchange as mainly private. I don’t think the mere fact that one of the people involved makes a living from audio automatically turns everything said between two people into correspondence that can be made public.

For me, the important distinction therefore isn’t simply between commercial and non-commercial communication, but rather the context and the reasonable expectation of confidentiality. A direct sales approach is one thing; a private conversation between two people in which business matters also happen to come up is something else.

I also don’t think your comparison with recorded customer-service calls quite fits, although I don’t know whether the standards that apply in the EU, and particularly in Germany, are the same everywhere in the world. Here, companies MUST make it clear when conversations are being recorded and explicitly ask for permission if, for example, a conversation is to be used. If a company tells me that a conversation may be recorded and analysed, that normally means it may be used for certain internal purposes. But that certainly does not mean that the conversation may then be made public for everyone to hear or read. Internal use and broad public disclosure are two fundamentally different things.

But we don’t have to debate this down to the smallest detail, and you’re the boss around here – so your rules apply, and I respect them.

Best regards
