Hi IFI team, I am pretty sure that running the unit high gain vs low gain will introduce some signal distortion (and higher snr), regardless of the op-amp used - how much of that will be audible? I am not sure, someone with an oscilloscope can measure the distortion. You probably need op - amp data sheet for the IFI unit in question
I don’t believe they are using an op amp or even a discreet op amp. I seem to remember them referencing some classic pro audio gear that they modeled the circuit after.

[QUOTE = "Haris Javed, poste: 14078074, membre: 435351"] Salut IFI équipe, je suis assez sûr que l'exécution de l'unité gain élevé vs faible gain introduira une distorsion du signal (et plus élevé snr), quel que soit l'ampli op utilisé - combien de cela sera audible? Je ne suis pas sûr, quelqu'un avec un oscilloscope peut mesurer la distorsion. Vous avez probablement besoin d 'une fiche de données d' amplificateur opérationnel pour l 'unité IFI en question [/ QUOT
Re hello, well on that there should be more distortion on the position + 18 db,

Over four year ago!!

On Mon Dieu!! Could it be released!! I gave up hope and stopped following this product a few years back. Checking back in I see an eventual release is almost a reality....maybe. Is there a recent stated price point for the ever elusive idsd pro?

bonjour, comme je le disais je possède déjà le iFI pro ican et je pense essayer le iDSD iFI, ce qui ne me rassure pas est le délai de garanti, trop courte, beaucoup de lecteurs HIFI jusqu'à 5 ou 10 ans de garanti comme Moon, peut etre que les responsables de iFI ne sont pas sur de la fiabilité de leur materiel, et comme ce ne sont que des cartes à intérieures en cas de panne, il n'y aurait rien à récupérer, merci pour les infos de la part de iFI pro,

Time flies fast, doesn't it :ksc75smile: ?

No op-amps anywhere in sight in the main audio circuit of our Pro machines. These critters can do secondary jobs, i.e. servo. But again, audio circuitry doesn't have any.

Yes, it does. I'll ask again, is there a projected price? As time flies, I believe the projected price flies up. It started under $1000, then I think it was $1500. Is there a recent projection? I own a half dozen iFi products, so i'm asking because I like your products and would consider the idsd pro..........at the right price.

Hello @iFi audio

Have you posted photos of the back of the iDSD Pro? The only photo Music Direct has is of the front, and the iDSD Pro has not yet appeared on the iFI web site.

Thanks

Not yet, but it'll happen very soon.

Thanks for this!

Anyone care to speculate on what that sync source selector does? Still no manual for the iDSD Pro on iFI's web site.

We'll explain what's going on on Pro iDSD's rear very shortly.

Folks, we have a major announcement.

iFi audio has recently returned from a couple of outstanding audio shows – CanJam in New York, USA and Bristol Sound and Vision, UK.

As promised, audiences had the chance to audition the pre-production model of the new Pro iDSD. This gave us the invaluable opportunity to gather feedback from the end user, directly.

We couldn’t miss out on the final chance to let our potential customers drive the Pro concept forward just one more time.

So, as is our want, we have taken the feedback on board and are tweaking the hardware and the software in response to these comments.

It seems that certain markets required the additional 2.5mm headphone socket and some the 4.4mm – so we’re doing both. Watch this space for more info on how and why!

Inevitably this will have an impact on the official launch date of both the Pro iDSD and the Pro iRack which we intend to launch together.

Skin says he needs more time (until the end of May) to implement these tweaks and will be able to give us a definite launch date nearer the time.

Yawn! Deja vu
May then probably August then postpone again till 2019
Yawn yawn
Why wait until a week before the previously-one-hundredth-time-postponed-latest launch date to then postpone again. One thing about ifi is they really know how to laugh in the face of their customer base.
