petersv Posted July 30, 2016 Posted July 30, 2016 (edited) Devialet firmware v10.0.2 released last week also significantly improves audio quality at low listening levels (ie -40 to -30) Edited July 30, 2016 by petersv 1
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 I've had a dev 120 beside my Class A Plinius and at moderate listening levels it stacks up very well. I do feel that your speakers need to be "sam-able" for it to really shine. Sent from my iPhone using Tapatalk Do you find the improvements are more pronounced in the bass region or whole audio spectrum when you switch SAM in?
petersv Posted July 30, 2016 Posted July 30, 2016 mainly bass and mid range, sam isn't supposed to impact anything above 150hz but somehow... it does
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 Best guess. SAM is supposed to fix timing errors so it is reducing time smearing over the audio range which is contributing to a more natural presentation.
Tony B Posted July 30, 2016 Posted July 30, 2016 Do you find the improvements are more pronounced in the bass region or whole audio spectrum when you switch SAM in? Only bass. The Dev is awesome for Stand mount speakers and can really get them punching lower 1
petersv Posted July 30, 2016 Posted July 30, 2016 A few months ago I had a Hegel H160 on order, then on the '11th hour' I discovered Devailet & SAM... SAM was the deciding factor, so glad I went Devialet (and the price difference was only about $100 difference new at the time)... took my bookshelves from around 49hz down to ~29hz AND improved clarity, air, presence etc.... very happy with SAM & Devialet, total bargin for what it is 2
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 Well, I mean, the bass is now correctly time aligned to the rest of the audio spectrum. A bit like time aligning a midrange and tweeter (perhaps)?
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 I can't see SAM working for my Triptych protoypes somehow. I have downloaded a file containing SAM data so I could work out a hack. My speakers will be getting down to 29hz without any bass boost.
wikeeboy Posted July 30, 2016 Posted July 30, 2016 (edited) mainly bass and mid range, sam isn't supposed to impact anything above 150hz but somehow... it does With regards to bass extension SAM only works from 150hz down. The time alignment works across the entire audio range therefore it impacts the whole spectrum. Therefore in theory, with SAM % set at 0 (no extra bass extension) there is still the benefit of time alignment. It is recommended to keep sam switched at all times, and just at 0% if you don't like what it does to the bass. Edited July 30, 2016 by wikeeboy 2
Tony B Posted July 30, 2016 Posted July 30, 2016 I have a medium to large room at 8.5 x 5m. I ran SAM at 100% on my stand mount speakers with great success.. When I had my floor standers running I dialled it back to 35%. It was just too much and as could feel the bass hitting you. 1
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 The DEV seems to be very divisive. I guess it is partly the radical nature of the system.

It is recommended to keep sam switched at all times, and just at 0% if you don't like what it does to the bass. Funny though, when I open the file that gets made in the configurator, the SAM data is a simple 2 column series of rows. The audio frequency is in the left column and then there is a figure in the 2nd column. If I read this is the context of something like what Bohdan is doing - http://www.bodziosoftware.com.au/ - that makes sense. Speakers are linear phase. If I adjust the output to make it flat I in fact also adjust the phase and also make it flat which removes timing discrepancies. Which aligns the output of the bass below 150hz to the lower midrange.
Guest Sime Posted July 30, 2016 Posted July 30, 2016 I'd love to hear them on my system, but it'll never happen unfortunately.
wikeeboy Posted July 30, 2016 Posted July 30, 2016 (edited) The DEV seems to be very divisive. I guess it is partly the radical nature of the system. Yeah i've never come across something as divisive... well, maybe when class d was introduced and their was massive negative sentiment. What frustrates me is if someone listens to an all Audio Research setup and doesn't like the sound, they generally don't diss the whole brand, its just a case of it not being their particular flavour and at the end of the day everyone has individual tastes. With Devialet though, if someone doesn't like the 'sound' the brand is really bagged and dismissed as an over priced lifestyle product that 'just looks good'. Edited July 30, 2016 by wikeeboy 1

That just doesn't happen to Devialet, you can put Class D amplification to that list too. People spend 5 to 6 digit numbers on gigantic Class A/B and class A amps and out of the blue comes this tiny Class D amp with fraction of the cost of their amp with more power and better specs, how dare, it must be crap. To be honest though there are plenty of crap Class D amps out there but that goes for anything. There are plenty of crap examples of product X and good ones too. 1
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 Yes. There are two factors. Firstly devaliet is ruffling a lot of feathers in the audio industry due to their marketing style. Secondly they are finely crafted designs. Seriously if you stuck them in a pop riveted galvanised steel box people might start to listen to them on their own merits instead constantly comparing them to life style gear.
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 And the irony is that the technology whilst not new in concept is a great marrying of class a steering class d. I wonder if we went back in time to the early days of Quad, would we have seen people do something similar?

Yeah i absolutely hate Devialet's marketing. You can really tell they are backed by LVMH. Carrying on about your tech/amp being the best in the world and the 'best' sound is like nails down a blackboard. That kind of rubbish probably works in mass marketed consumer stuff, but really irks the audiophile crowd, me included!
Guest scumbag Posted July 30, 2016 Posted July 30, 2016 Their marketing people basically don't understand our care about the sensibilities of us audiofools. Fragrance, cosmetics and fashion are markets in which one has to resort to unfounded hyperbole in order to be simply heard above the crowd. Simply put, if they can capture the international lifestyle market then they don't need to worry about us lot. That market far exceeds the rather niche audiophile market.
Volunteer sir sanders zingmore Posted July 30, 2016 Volunteer Posted July 30, 2016 (edited) The niche audiophile market won't like Devialet in the long run anyway. Regardless of how good their product is, audiophiles like to tweak and change components. All in one solutions like Devialet don't really allow this. Edited July 30, 2016 by Sir Sanders Zingmore 1

Is it really any different to an intergrated amplifier? The only real restriction I see is you can't play with external DACs.
Tony B Posted July 30, 2016 Posted July 30, 2016 Is it really any different to an intergrated amplifier? The only real restriction I see is you can't play with external DACs. Yes you can.. It has analogue inputs also.

I might have been interested in them in they were in a "pop riveted galvanised steel box " and the price reflected this. I do not need the fancy "expensive" boxes that some of these higher costing products use. Two thirds of the price is most probably in the box/packaging. Edited July 30, 2016 by rocky500
jt301 Posted July 30, 2016 Posted July 30, 2016 Yes you can.. It has analogue inputs also. I know it has which is converted to a digital signal before being processed and reconverted back to anolgue via its own DAC before being sent to the speakers. So I guess I'd question why anyone would want to use an external DAC with it.
