Why SAM don't support Lowther?

[David A]

Thank @ogs and @Damon for your detail answer.
Do we have any comparision of with and w/o SAM. Just my concern about looking for another one for SAM support or continue with SAM unsupported Lowther.

We all choose our speakers for lots of different reasons and I think choosing a speaker because it has a SAM profile is silly, whether or not you have a Devialet or are thinking of getting one.

When I bought my Devialet I had a pair of Dynaudio Contour 1.3 SEs. I bought them years before the first Devialet was released so SAM wasn't an issue. When I got my 130 I tried it with and without the SAM profile and found I preferred them with SAM but they sounded great with the 130 without SAM. SAM was a nice "bonus" but I would have bought the 130 whether it had SAM or not.

Some months after getting the 130 I upgraded my speakers to Focal Sopra 2s, a very different speaker with a very different interaction with my room. Once again I tried things with and without SAM. I prefer the Sopras without SAM. I suspect part of the reason may be the fact that my room is a bit on the awkward side for a speaker the size of the Sopra 2s. I can get them to work very well in the room but that bit of extra bass extension and how it loads the room may be a little bit too much. It changes the voicing of the speaker at the bottom end and while I like the extra extension, I prefer the way the low bass sounds in my room without SAM.

SAM isn't only a speaker issue, it's also a room issue because of that extra extension, and it does change the voicing of the speaker at the bottom end. If you like the way the bottom end of the speaker is voiced when SAM isn't used, you may not like it with SAM. It's a bit like whether you like milk or sugar with your coffee. There's an element of personal taste involved. SAM is not a magic bullet for making any speaker with a SAM profile better, either in every room or for every person.

If you like a speaker with Lowther drivers and you think a Devialet works well with it, then you've got a good combination for your own tastes. The fact that there isn't a SAM profile doesn't make the combination work any worse. I works the way it works and if you like that, then that's what you're looking for. If you have a Devialet and you're looking at changing speakers, try them with the Devialet and it a particular speaker has a SAM profile then try it with and without SAM but at the end of your search what you're going to buy is the speaker that sounded best with the Devialet and if that speaker is a speaker without a SAM profile are you really going to say "No, I'm not going to buy it because it doesn't have a SAM profile. I'll buy another speaker I didn't like quite as much because it has a SAM Profile."? That sounds a silly way to go about making your choice because it is a silly way to make the choice.

SAM is an option you have with some but not all speakers. If your speaker has a profile then it's a handy option to have but there's a lot of speakers like full range electrostatics, full range ribbons, and pretty well every DIY speaker  you could consider which includes a lot of speakers using Lowther drivers and there's a lot of really good speakers amongst those speakers without SAM profiles and if you really like one of those speakers with a Devialet more than you like any other speaker you've auditioned then go for it.

SAM's a nice option to have but if you find a speaker you really like, it sounds great with a Devialet, and it doesn't have a SAM profile you're not missing out on anything. You're still getting great sound and that's what you want to get.
