Omnia has been the best way to get easily get you that solid faithful bass and soaring high end, admittedly with a touch of grunge on some vocals. Let's just say that Frank believes in retaining as much dynamic punch as absolutely possible with the occasional bit of roughness around the edges. The output is very faithful to the source material, which can become its downfall when hit with some modern mixes with over "Aural Excited" vocals and too much peak limiting. The Omnia 6 really is a legendary processor and when I first heard it on the air in our market back in 2001 it absolutely melted the competition. The station that was running the Omnia 6 has changed to an Orban 8500 recently but to be honest I think the Omnia 6 was still better

Even though the Omnia 6 is now over 5 years old - I suspect it was just a case of - "oh the Orban 8500 is flavour of the month, let's get it on the air"... It takes more tweaking compared to an Orban to get exactly what you're after but it's worth it. I've got no doubt an Omnia 3T can be moved into that sweet spot with careful control of input levels, and if you're a real quality freak, can't be bothered to wavegain or set levels manually on your music library and/or have untrained jocks who don't watch their levels and/or your station still plays direct from CD - just throw an Ariane Sequel in front of the Omnia for spectacular results.

Bob Orban provides a much more controlled output from his processors, which are effectively plug and play boxes with a very controlled sonic signature by design - this provides an amazingly smooth, extremely dense sound but compared to the source material it's like its being remixed in a real time manner. He believes in maximising sonic quality and especially source to source consistency, and is very good at keeping vocals at the right place in the mix, whether that be where the original artist intended or not. However one of the problems I have with his boxes, especially the AM ones is the bass sounds artificial. eg, its almost like it is faked... I'm guessing what is happening here is he is smoothing out some of the peak bass energy and lengthening its duration slightly to give more impact. It gives you that big booming bass sound that's not really realistic compared to the source material but for a lot of people it's a nice effect. Also I find the HF energy is a lot more controlled which does remove a lot more ambience that Omnia boxes let through. I have to admit the Optimod 8500 has gained a lot of ground on the Omnia 6 and is definately almost achieves an Omnia style impact

DSP-X - well I'd like to say I believe Scott Incz has produced a very balanced product which from my use seems to produce the best of both worlds. It's definately more Omnia like than Orban, and I think really competes on it's own merits. Especially with the addition of the Ariane technology in the DSP-Xtra, it's probably the most dynamic, clean, and LOUD processor on the market today. Like the Omnia, you need to spend time customising your preset to get the sound you're after - but isn't that what the fun of audio processing is all about!?

That's my opinion anyway based on what I've heard in my market... YMMV
