Listening to Devialets SAM technology on my fact 8s for the first time tonight. WOW! BASS!!!!!!

Id tried SAM with a pair of Dynaudio focus 160s a few weeks ago and actually didn't like it, but with my fact 8s, it's very good indeed. Bass is pretty spectacular now from these otherwise lean leaning speakers.

I can A/B the SAM with the remote so my first thought was that this new bass may degrade the mids and highs, but that does not appear to be the case. Jury's still out because I need to hear it with more material, but so far liking what I'm hearing. Impressive!
 
This is so cool to hear, but I wonder why the formula for the 160's didn't work as you expected. Any ideas?

My guess is the dyNaudio focus 160 is a speaker that is already very accomplished in the bass department. So with the SAM, it was a bit too bass heavy. The fact 8 on the other hand really mates perfectly with the extra bass.

It doesn't seem to add bass that doesn't exist. Meaning tracks that have little bass content remain so, but tracks that do have prominent bass, the bass is deeper and more impactful.
 
SAM is really interesting technology and kudos to Devialet for making it so speaker specific.

Glad you are loving the SAM technology, if we can get enough votes for my Strads, I may give the Devialet a try.

As someone else on AS reminded me - you can dial down the SAM calibration anywhere between 0 & 100% . That might help

jaxwired,

Did you try various levels of SAM ob both speakers? You might have liked a reduced level on the Dynaudio.

No, I did not try that. I simply tried "ON" or "OFF". You may well be right. 100% on seems to be quite good with the PMCs though.
 
But it is a BIG limitation until they decide to do something about it. Maybe not for others. And there's no guarantees. :(

I agree whole heartedly. I don't understand why companies are designing DSP/software with these limitations.....right in the middle of the hi-rez frenzy. At least reach out to 192, or 384. I'm sure it's a much bigger undertaking, but would build in some future-proofing. Everybody is still caught up in the high numbers game at this point.

Good ole DSP is finally getting some much needed praise.

But shouldn't DSP also consider the placement of speakers in the room and the subsequent interaction?

Is this as complete as what Acourate and Spatial computing offer?

You know what just struck me as being really ironic and kind of funny when you consider all of the digital lovers who proclaim their distaste for all things analog? Digital has to be converted to analog in order for us to hear it. There is no way around it, it's just a matter of how the digital conversion to analog will take place. On the other hand, there is no reason why analog can't remain analog from the time it's recorded until it comes out the other end of your speakers and fills your room with sound.

Acourate and AudioLense are far superior, I'm sure. DSP can be used to correct just the power response of the speakers themselves, or also include some room correction. Acourate and AudioLense even correct for phase, which can be made much worse by equalization. Equalization without phase correction can sometimes cause more problems than it solves.

Very true, but storage of data works far better as digital than analog. Analog data degrades over time. Everytime you play vinyl or tape you've degraded the original a bit more. Digital is static the data never changes. Play it a million times, sounds as fresh as day one. Not to mention the physical limitations of dynamic range that can be imbedded in vinyl. Digital has no such limitations. Digital is a far superior way to store an analog signal if you want to capture the original signal without limitations and you want to maintain the fidelity of that signal over time.

Agreed,

I see the very expensive (but desirable) FM Acoustics Linear Harmonizer can do equalization without the phase distortions. We got a nice demo of it in warsaw. I wish that stuff was more "affordable". LoL
 
So what's the early consensus on SAM?? I read some love it, others not so much.

If I understand this article correctly, Jeff took the S1 SAM configuration and used it on his Q7's and proclaimed it to be the best match for the Q7's he's ever heard?
 
I asked Devialet support about using the SAM profile for the a different model, but same brand...here is what they said:

"Dear Mike,

Thank you for your message.

Regarding SAM[emoji768] profiles, each of them are unique to a specific model of speaker.

For each profile, over 60 measurements were taken, measurements such as maximum excursion for instance. It means that every speaker has its own excursion. It could be dangerous for a speaker to take another profile than its own as the excursion might be different. It could indeed damage the speaker, and this is just regarding excursion maximum.

I hope it does answer your question.

Best regards from Paris,"

So, as of now, SAM voting for Q7 is at a whopping 4%...so given the above....I hope Jeff didn't damage those big Q7's.
