is not a big high end gear but the sound is amazing and very confortable this sistem i compare with high end gear to value $50,000 my audiophile friends audition my sistem and the said so i am very happy with that.

I own one and think its very good. It is my first outboard phono stage, and I believe its as good as any of the other built-ins I've owned ( Marantz, Rogue, CJ ... ) Im using it with a MM and it has never yet left me wanting. Hard to go wrong at that price also.

I think Stringreen was right, its your ears you have to please....Give it a go....

My advice is not to listen to anyone, but to enjoy your new purchase.
