I got home at 4:00 p.m. and saw a small box with "Mayflower Electronics" written on it. Oooooohhhhhh dang. I was so excited. However, when I first got it all set up and opened up Foobar2000, it all sounded very bland. I then realized my V style EQ was not activated. Instantly, I heard a difference (This is all coming from crappy on-board audio from a 50 dollar motherboard) Wow, the bass felt tighter, the treble felt more "Sparkly". I didn't expect the amp only version would make much of a difference in the sound quality. I was wrong... The vocals are so clear! I heard background instruments I never heard before. I also happened to get the maple limited edition as my headphones are ebony wood and I have lots of wooden accents in my room. The color is that of my guitar. Anyways... The unit is very small and light. But doesn't feel cheap. I also tried it on my Galaxy S4. Wow, I can actually hear the music now! This thing will get your music loud enough to do physical harm to your ears... Haha. I don't want to bore you much more.
I would also like to note, I was using the "Meze 88 Classic" headphones. They have a very flat response curve. (Also why I use a V style EQ) I listened to Country, Classic Rock, Hard Rock, and Zweihander. :)
Keep in mind, this is only the first hour of listening.
I love this product and will recommend it above anything else I've used. :)
