As people were praising Diva as a replacement for analog stuff I decided to do a little test.
The test sound is simple to be as fair for both Diva and Matrix as possible.
In Diva I've selected Init Jupiter 8 preset. Then I've slightly detuned 2 saws (default analog1 algorithm was selected for oscillators) and put the env2 mod for filter to the max (as anything below may respond differently on both synths).
I haven't touched envelopes so Env2 is set to nothing but a short decay for a more "stubby" sound.
Then I did the same preset on Matrix.
The audio file below is testing that preset at two different settings. Divine precision is used. Both are recorded as mono and a very slight delay with the same preset is added to both. I've tried my best to make the volume as equal as possible.
The first part of the test: filters fully open and no resonance.
The second part of the test: filter cutoff at ~50%, filter resonance at ~50%. Now on both synths cutoff and resonance settings respond differently to the same values, but I've tried my best to make M1000 sound as close as possible to Diva's filter settings.
My personal opinion is - no, Diva unfortunately can't stand up even to what people here consider a "lesser sounding" analog synth.
To me M1000 sounds more 3D and as filter comes into play the gap becames only greater. With Diva it feels like filters just cut out frequencies and that's it - while on M1000 they colour the sound. Oscs also feel "squished", while on M1000 they feel more "3D" or something. And yep - I've tried turning max. detune and drift knobs in Diva. They only detune oscs, but they don't give them that "3D". Finally it feels like there is some low pass filtering going on with Diva even at a fully open filter (I've tried all of them, Jup8's cuts out stuff the least while Moog's filter sounds the worst). I've checked spectrum and I may be right - here is a "spoiler" pic: http://i.imgur.com/N3Zb2.jpg
