Wow guys ..... I am the OP here. And this thread has went waaay whack.
Let me start off by saying this : I NEVER intended for my thread to be a complete review. I run two separate businesses, and work 12 or more hours every day. I do not have time to write an extremely thorough review always. And also consider, I am NOT a writer in the first place.
My intent was to simply BE VERY KIND to you ..... Fellow enthusiasts and Headfiers, and tell you of a very inexpensive and unassuming product that reaches leagues above it's price point. For only $139, I figured you could pick one up and test it for your own self, and simply return it if you did not like it ( Amazon ).
But let me go ahead and try to give up a bit more insight, especially since ALL of you are paying me so much as a reviewer and writer LOL.
Some products are really easy to get a handle on and put your thoughts on it's sound into written words. Those products have very simple colorations or traits that immediately make a verifiable and definitive impression. They are either warm, musical, and full bodied ....... OR they are more lean, thin bodied, and anylytical sounding. They may sound slowish or fast the way they handle percieved pace and rythem. They may roll off highs or miss out on lows.
BUT when a product just sounds lifelike, with almost ZERO sound of it's own, it is VERY difficult to describe. Because it just sounds right. It is essentially TRANSPARENT to the original recording .. Without editorializing anything. Without ANY readily apparent weaknesses, or traits of it;s own. Then it is VERY difficult to describe. This usually is reserved for very, very expensive equipment that is properly designed. AND THIS IS HOW THE HEADSTREAMER SOUNDS ..... or doesn't sound LOL.
It just gets out of the way and lets the rest of your system dictate the end result,
I did not test the HS with a lot of different headphones .... so I do not know how it behaves across the board. BUT I did test it with what is a studio/stage monitor type IEM that is famous and respected for being VERY, VERY neutral and transparent. The GR07's are a great evaluation tool. And combined with the HS they presented music simply lifelike and honest.
THAT makes the Headstreamer a raging steal at $139 !!!!!!!!!!!!!!!!!!! And that is all I was ever trying to say.
Now if you look really hard at everything I just wrote, you will see there is basically ZERO more info than my thread starting post. It is simply a great product that DOES NOT color or alter the sound like the other amps I tested did to some extent.
If you want to post here and ask me VERY direct and pointed questions, i will do my best to answer them for you. But I can not say anything else to describe a sound quality that is simply life like. HTH
