Some impressions on the Quickie -> Emotiva vs Emotiva without preamp for HE-500:
Ok look I'm really scared here to be honest. These results I'm hearing aren't supposed to be possible. I keep listening to various songs back and forth between Emotiva with Quickie and without, but I honestly think I hear it.
- Vocals are smoother, less sibilant
- More sub-bass rumble
- Better bass detail and better texture, more control <- This one is very apparent
- More body and definition on instruments that gives more realism
- Substantially better soundstaging and separation! (~15-20%) <- This one I thought I noticed early, but was afraid to believe, but after more listening, it's there. Really opens up the sound!
- Smoother sound throughout all frequencies, especially at louder volumes
- More revealing??? <- especially bass as mentioned, but there was a moment in a song I never realized that background noise was actually a bass guitar riff going on. Before it was just some background noise that was kinda meshed together, but now I hear distinct strums.
I'm at loss of words. I really hope this is some placebo effect, because I cannot believe there is this much difference. I'll have to compare with using the Crack as a preamp, but I'm pretty sure the difference was not this big. The Quickie is definitely warmer than the Crack. It's on the level of warmth as my Baby Sophia, but the Quickie + Emotiva combo resolves better by far. The Baby Sophia is warm, but less resolving than the Emotiva.
For $100 and about 5 hours of building time, well needless to say I think the Quickie is a winner! Honestly though, I want someone else to confirm what I'm hearing, because even now it's hard to believe there is such a big difference.
Is this the magic of DC power? Gotta start looking for battery sales. A set cost me $20 at the local convenience store.
