At the level you are at, don't even BOTHER trying to get the best 'sounding' eq or anything like that. Complete waste of time. Look at a few of the eqs available in SONAR and see which you find makes most sense and is easiest for YOU to use.
Sonitus is very nice and easy to use. There is nothing wrong with it. The quad curve is good too, though you may find the controls a little more confusing as it's trying to be compact.
I'd suggest just using Sonitus for now as it has a nice graphic display showing you an idea of everything that's happening. I think it's a little more user friendly for a beginner. Once you master and fully understand it, all other eqs are really just the same.
You should always try and urge to do the best you can.
If you talk about get wonderful pro sound it all start what converters and preamps you use.
********About Gear *********** Check your specifications. You want to look for
Dynamic Signal to Noise ratio (SNR): This is a good measurement how good your audio card actually sounds. The difference can actually be like someone took of a blanket of your speaker's compared to low range gear.
Your audio card or converters dynamic
Signal to Noise ratio SNR should be between minimum 115db up to 130db.
Signal to Noise ratio (SNR): 118 dB RMS unweighted, 120 dBA UAD Apollo, SSL Alpha Link, Lynx aurora, AVID HD I/O and some of the RME products reach that.
As you can see if you check, most common low range products reach up to 102-108db... (No names)
You get what you pay for.
Preamps & Compressor. That is one of the biggest myth out there. Of course there are some really nice preamps compressors but sometimes low range sounds better then expensive unit. In my own opinion "Great River"products is just a joke. I have listen on other products from Great River too and I saying it's nothing special. Don't waste your money there.
Products from ART, DBX, FMR, SPL, NEVE, Focusrite, SSL, Manley, Daking, Chandler Limited, Elysia, Drawmer all sounds amazing in their price range.
