Review: Excellent would buy again. - I just purchased this and have used it for over a week it came packaged nicely and the tubes were well protected and fit perfectly. It sounds amazing and I use it connecting my TV to a powered 1200watt PA speaker and it sounds next level quality now. for those of you that don’t know tubes that well go research tube Guitar amps, it’s the exact same technology and what it does is it rounds off the tone from being so digital and gives you more depth clarity and organic sound. Btw I’m not a payed sponsor
