I bought this to connect a vintage Sony direct drive tt to a cheap bookshelf unit in our bedroom. My boyfriend wanted to ditch the large component system to save space, but after researching suitcase players and realizing how unreliable they seem to be, I felt reluctant to downgrade *that* far. I was also hesitant to pour too much into connecting to our bookshelf system, as it's likely not long for this world, either. I took a chance on this little preamp because the reviews were good, and the price couldn't be beat. Admittedly, I was expecting this to be a case of "too good to be true", but even with the cheapo bookshelf system, there is no hiss or buzz. I also added two additional speakers at the same time, but initially checked the preamp using the system's lackluster native speakers; the sound was more than decent, so I'm impressed. My only "complaint" is the ground connection has a flat washer, not the serrated type for older systems with a bare wire. It's a minor critique, but considering there's probably a decent chance you're using a preamp because you're connecting a vintage component, it would be nice to have the option to sub that piece in, right out of the box. The RCA ports are also a little close to the overhanging lip of the upper casing, so chunkier connectors may face a tighter fit, as is the case with my particular unit, (which my dad thinks he bought around '77, for reference.) Again, a minor note, but worth considering, depending on your particular needs. All told, we're very happy with the performance, so far.
