Regarding the sound quality...
In short this thing has made absolutely everything I've thrown at it sound better, and encouraged me to get a lot more creative with my EQ tweaking. I've used it extensively for extreme sound design work with great results, and it's CPU efficiency also makes it a prime canidate to throw on every track during mix down. We've all heard the tales of the classic Neve EQs adding a certain magic sparkle to everything you throw at them. After taking a good hard listen to a great many of the EQ plug-ins available today, the Sonalksis SV-517 is the first one I've come across with the quality and character to justify this sort of mythical description. Ironcially, a trip over to the Sonalksis website reveals that some of the company founders are former AMS-Neve R&D engineers, a fact which should instill enough confidence in even the most hardware proponents to at least take a look at this one.
Quite simply the finest sounding, best designed plug-in EQ I have ever had the pleasure to work with. While the price may push it out of the weekly allowance range of the average weekend knob twiddler, anyone making music professionally simply cannot afford NOT to have it. Do yourself a favour, head on over to the Sonalksis site, and download the demo to check this puppy out for yourself. The proof is in the pudding as they say...
I recently picked up Sonalksis' new EQ plug-in after trying every demo and freeware EQ I could get my hands on. While the options for surgical EQs are plentiful in all plug-in formats, the number of parametric and analog emulations which imbue a DESIRABLE coloration is, in my opinion, decidedly slim. While my music generally fits snuggly into the experimental electronic realm, my interest in reggae and clasic dub has lead me to try and emulate a lot of traditional instrument sounds (drums, bass, guitar, organ, melodica, etc) using software. Because these instrument sounds are most often presented under heavily processed conditions, I struggle to find ways of preserving some reference to the timbral character of the instrument without being restricted by the traditional ways in which these instruments are physically played. One of the most effective ways I have found of doing this is by trying to emulate the ways in which these instruments have been tradionally processed i.e. wah wah for guitar-like sounds, heavy compression for bass and drums, etc. When speaking of classic reggae and dub tracks, 'thickness','warmth', and 'grit' are certainly some of the first adjectives that spring to mind when trying to describe the overall tonal quality. These are certainly not words you would typically use to describe plug-in EQs. With the release of their SV-517 EQ, Sonalksis have changed all that.
