This ZO device sounds like it would bring similar results as I get playing around with this hardware EQ I use. The technique is very similar, using hardware EQing to raise pretty much the whole frequency range (bass is raised even a little higher which I also do so it's like very spot-on to what I do as well) but in this case they have a preconfigured external device doing it. If it does bring similar results I'm sure lots of people would enjoy it. The main difference occurs in the presentation, the sound gets more forward/"in-your-face" sounding, there's a demo vid which sorta tries to simulate it, ofc it's not possible to give the exact experience but it reminds me quite a lot of turning on/off my EQ settings. Everything gets "stronger"/more forward, not just bass. I admit they are talking a lot of mumbo-jumbo on their site though and trying to explain it in words like it would be a magical device doing all sort of fancy stuff to the sound while it's basicly simple hardware EQing they're using and trying to cover that up with tech mumbo-jumbo talk. This page says it all though with no text required

Don't get me wrong though, I really like the result of this sound you get, so if it works/sounds like I think it does I'd find it a very neat device that pretty much every1 could enjoy and aren't limited to specific soundcard/DACs etc. as sources to be able to achieve this kind of sound. If you like forward/engaging/"in-your-face" sound then you'd love this thing.
What I don't yet quite understand though, how can boosting the whole range bring difference compared to simply raising the volume slider? I've compared this numerous of times and it just doesn't sound the same if boosting the volume as boosting the whole frequency range on my hardware EQ.
BTW, what does it cost? Couldn't find any buy links on their site.
EDIT: ok I found it, $120, a bit expensive for what it does IMO but the result what you'll hear in the sound is well worth $120 though, for example I think my XB500 starts sounding more like ~$200 headphone rather than $50 headphone with applied EQ-settings. This is not such small difference that most amps provide (depending on headphone etc obviously), it should be a very audible difference similar to enabling BBE on Cowon players.
wind016> would be awesome if you could try it out as I think you would based on your opinions regarding Cowon player enhancement options and the way you EQ. I'm positive this is the best technique to enhance the bass without ruining the overall sound as you get "more of everything", details in mids and highs also pops out more clearly so it's not only a gain for a basshead. I believe you'd be the right person to review this thing. I could do it as well but I live in europe so it's a bit hazzle as I'm not sure the shops ships to Finland and I already got experience of the "effect" and think it would be more interesting for some1 else to hear.
