This is complete garbage. Microphonic as hell, mono poor quality audio with zero actual boost or clarity. Buy a goodwill boom box, it'll sound better.

I like that it has 4 inputs and 2 outputs, and they work simultaneously, so I can have 1 out put to one set of speakers and the other to an other set. Works good as a headphone amp, not a lot a noise from the unit works as intendent bass thru headphones (IEM) not as punchy as i would like it to be, but for the price,it's good.

This preamp doesn't have a bunch of features, but it has what other don't. 4 inputs and 2 outputs. The knobs on the front and connectors on the back are all sturdy and secure, nothing wimpy on the construction.This unit worked fine out of the box and has continued to work for a while now, no issues. The unit is quiet and noise free, even when turning it off there is no power bump like you hear on some. The case is plenty thick aluminum and very sturdy, the paint is robust and doesn't chip or mark easily. I do wish they had gotten the bass and treble in the correct place. All other stereo's have bass on the left and treble on the right, these are backwards and it screws me up every time.The sound is quite good, I would rate it a 90 out of 100. There is a small bit of distortion if your really listen but for this price it's fine.The tubes in my unit were also tilted a bit, but not too bad. I will take it apart and straiten them but haven't yet. Probably got impacted a bit on one side during shipping. The attenuation meter on the front works properly and was calibrated to be accurate. I hooked this up to a Carver M500 amp that has dule meters and the numbers matched as far as I could tell, with music playing it's a bit hard to asses. It's very small so it's hard to read accurately. It's like having your car speedometer that small, like a 1 inch meter, you would not really be able to tell with any accuracy what speed your going. Then throw in the varying music and it's even harder. Regardless of what music I was playing, it was real close to the Carver amp readings. It's more of a visual effect on the preamp, as it's not giving you a wattage output, I like the look and it does work.The headphone section works great, plenty of power. My Yamaha headphones had fantastic bass response thru this amp.Over all a great little preamp.
