JTS MA-123

I am using this attenuator in my hifi setup at home, the reason being that I connect a streamer (Wiim Pro Plus) directly to a power amp. Since the former has only digital attenuation it sometimes messes up with the volume (especially when I use Air Play) and sends full signal to the power amp. After reading online about these attenuators I decided to purchase a couple of them and tried them connected to the power amp. They do not introduce any kind of noise nor do they alter the signal in any way that I can subjectively perceive. Also, they do their job: Even when I crank up the volume to insane levels it remains within the boundaries of an SPL that doesn't damage my speakers and hearing.

Audio-quality-wise my pair of these both work great (at the time of purchase, anyway). I'm using them to bring down really hot line-level signals before they hit my converters, and there's no unwanted artefacts or nasty business.

The build quality is where you save the money compared to Shure etc. I've used the Shure inline pad a lot and it's definitely more rugged than this one. The casing here is plastic, not metal, and feels like it might not survive a misplaced kick or mic being dropped on it etc. Fine for situations like mine where it stays wired up in the same place all the time, out of trouble. Maybe not so fine for getting thrown around at a live venue etc.
