Keep in mind I'm comparing EQ1 with another very well respected parametric EQ, the Velodyne system so my differences are most likely not going to be as dramatic as EQ vs no EQ
Here's the results of my listening tests so far, all positive. Sorry its a long post
I setup a/b comparisons on 3 very different recordings using SVS with Magnepan fronts as large (my current setup), then changed fronts to small. Next, I used my "best" Velodyne EQ with mains as large & then small. Then back & forth to verify subjective impressions for small+SVS vs small+Velodyne and then large+SVS vs large+Velodyne. A lot of setting changing as quick as I could so I wouldn't lose too much audio memory.
Recordings were -
Morph the Cat 5.1 DVD-A, track 1 - lots of electric bass energy & drum
Superbass 2 5.1 SACD, track 1 - acoustic bass jazz with very low extension, detail in notes & in track 1, no drum to interfere with hearing detail
Peter Gabriel Security, 2.0 SACD, track 3 (I Have the Touch), beginning has 20 sec or so bass & synth drum hits with a constant guitar chord in background before vocals begin.
The Gabriel disc being 2 ch, I wanted to see what the effect of small vs large on how much effect EQ would have on whatever was being sent to the subs.
It was subtle but discernable, repeatedly, although it probably wouldn't be noticeable to the casual listener using as background music. Morph & Superbass were the best for hearing the difference, I'm sure due to the separate LFE channel.
In order of preference, I picked -
1. SVS with mains as small
2. SVS with mains as large
3. Velodyne with mains as small
4. Velodyne with mains as large - comparing SVS + large to Velodyne + large was harder to tell apart but SVS still seemed a bit tighter, more impact & clearer compared to the Velodyne.
The best way I can describe the difference is SVS made bass a little tighter, less bloated and easier to discern other sounds in the mix. At the same time, there was more impact from lower freq's. I could feel the impacts in the air more than just the Velodyne. Hearing both impact & clarity at the same time was more apparent with mains set as small, which makes perfect sense since the SVS has no effect on the mains. To my surprise I thought small was better than large - I guess I have to re-evaluate setting my fronts to large
On Superbass, the ringing or bloat being reduced, the notes seemed tighter & a tad quicker so that succeeding notes were a little clearer when plucked. Great recording to tell the differences.
Is the Velodyne EQ bad? Emphatically, not at all! The sound is close enough that in my room & setup I could easily be happy with it.
But the SVS wins out, it's just enough better to make it a nice addition to my system.
I also now understand what is meant by equalizing in the time domain vs just freq equalizing. Reducing that little bit of note overhang makes a difference. I think my setup probably didn't have too bad decay times to begin with, that's why it seemed more subtle.
I suspect with a tougher room with more reverb, the SVS makes a world of difference. It's too bad they discontinued the product but I understand the biz reasons. You all with MultiXT32 receivers have a nice system to use.
Sat & Sun's are movie nights so I'll get to compare them soon. I've got lots of movies with lo freq bass to pick from
Sorry for the long review but I'm not one to say it's great & move on.
I try hard not to be convinced because I bought it since no one is 100% immune from placebo effect
Thanks for taking time to read this
