|My favorite piece! Like everyone here basically said about the warm fuzzy's, it's right on for that. The thought of losing some clarity for me was kept by using the stock head unit to drive some dash & back speakers. I also installed a center dash speaker not far from the MTube to work with it and used the MTube to drive the rest speakers & subs. Quality is a bit grim on how its made and lit up and the power input is a real bad idea for randomly falling off. But sound quality is amazing. The real scary part is how Soundstream appears to be gone now. No web site or working direct phone lines. I had hopped it was temporary but its been awhile now and I really wanted to get another one for another car but now I'm not sure.|

|First of all, I already have a really good system consisting of JL Audio, Image Dynamics, and Premier equipment. I added the Mtube8 not expecting much, just maybe a warmer sound. It actually improved things better than I thought. The imaging on the front stage improved, midbass upfront improved, and instruments seemed to take on a life of their own instead of being bunched up in a big ball of sound. For some reason, violins and flutes stand out instead of being lost in the background. I like that!
IMO: The tubes do their job. And there is an audible difference. So yes... this product is well worth its price.
Cons: The lights in this unit are way too bright. I wish a dimmer was worked into it somehow. Also, the input configuration can be confusing. There are no colors or left/right markings on RCA jacks. I dont get that.
Overall tho, I like this product and am very happy with it. High end sound at a low end price. What more do u want?|
