Greetings,
I am using Sonar X3 Producer with ProChannel EQ, etc. I know that this EQ has been updated in the latest version, and I am about to upgrade to that.
In the meantime, I have discovered FabFilter Pro-Q - which is quite good, and sounds better/more features than the ProChannel EQ in X3.
My question is this: I know that the EQ has been upgraded in the latest Sonar version, but: is it as good as the FabFilter Pro-Q?
I would love to hear from users who have/have tried both.
Thanks!

Hi pdarg,
Sonar latest version here, and while the ProChannel EQ and new LP EQ are quite good, I think the FF ProQ2 is still better and more full featured. I don't know that I can say one sounds better than the other, but the FF just has more stuff you can do with it. The only thing I can think of that the PC EQ does that FF doesn't do is the console curve emulations (FF has gain-q interaction but it's not as configurable). FF has AutoGain, slope control on bell curves, resizeable interface, Tilt curves, and (IMHO) a better UI.
 
Don't get me wrong, I like the EQ's in Sonar and they're genuinely good serviceable EQ's, but FF is the one that gets used most often around my joint.

Hi. I do not own the Fabfilter Eq, but I think the new LP Eq is really good. It comes with Professional and Platinum, I believe. It can be used in linear and nonlinear mode. 
All the best.

Thanks for the opinions - keep 'em coming!

I've tried both.
 
I would personally not pay an extra ~$180 to get the FabFilter Pro-Q.  
 
Yes it has a few more features, but both also have plenty of features.  The sound quality - both are more than adequate.  
 
The new Sonar EQ is, as expected, very taxing on the computer resources in linear mode.  One thing I do not remember is testing both.  Though when running in that mode, I'm of the mind set that is used for Mastering of a single stereo file, and did not have issues with that.
 
 

As a single purchase the FF is pricey. It's a lot better if you get a bundle during a sale.

I use my ProQ2 as go-to EQ. I don't know that it sounds any better than the QuadCurve or LP but it does at least as much as both and I prefer the UI and additional options.

I have Fabfilter EQ. However, I use QuadEQ for tracks. It does the simple EQing very well and I have never heard any sound problems. Neither has any of my clients said that my EQ is not high quality enough...
Fabfilter Pro-Q2 is good for the master bus and individual buses where I need for example Mid/Side processing.

I think the new LP EQ compares very favourably with Fab Filter. To the extent that I wouldn't significantly miss Fab Filter if I didn't have it any more. And I rate Fab Filter very highly.
 
Like Panup, I wouldn't use either for a general purpose EQ though; sledgehammer to crack a nut in most cases.

I don't really get that, LP sure but FF is super low on CPU. It's not a sledgehammer unless you make it one. But to each their own.

Btw, to the OP - the ProChannel EQ, also called the QuadCurve EQ, is the same as the one that shipped with X3! The LP64 that is in X3 (64-bit linear phase "mastering style" EQ) is the one that has been updated. It has more of a FabFilter style interface now. It doesn't have a ProChannel module so it doesn't replace the QuadCurve. It is also by definition a a little heavy on CPU because of the linear phase thing. The QuadCurve has no linear phase mode so the two EQs should be seen as complementary. The FF has all these options switchable so it's more of a catch all thing. That's what you pay for I guess. It doesn't have a ProChannel module though.
