User Manual of Nobsound B100

Warm tips:

  • Only in the condition of large dynamic music and much bass effect the VU meter will work.
  • When inserting the tubes please pay attention to the direction, the arrow on the tube should be aligned with the bulge on the tube socket.
  • 6P17A vacuum tubes are not easy to be found on web. But its unique performance will bring you an unforgettable sound experience. If you want more spare tubes, please contact us directly.

On and off switch you hiding behind, why?

I don't like at all the location on and off switch.

Sounds great!

I really wanted to like this and have it be my long term solution.The size is great for a desktop, the sound is great, the build quality is excellent. They really did a good job with the fit and finish of the cabinet.My main problem is with the power button. It is situated on the backside, amongst all the wires and connectors. I like to turn my electronics off when I am not using them so they don't drain energy. With this unit, it was inconvenient to get to the button, and worse, the fiber optic cable comes out almost every time I fumble around on the back to turn it off.One minor gripe is that I love the little gauge on the front, but it only moves when you really have the sound cranked up. Using it for my desktop volume doesn't even move the needle.The design is a little polarizing. I like it, but my wife came in, took one look and said, "What, are you going for the mad scientist look now?"If you don't need to turn this off regularly, it is a great little amp!

Great... but far from perfect.

This little unit is great. That's the TL;DR.I'm not going to really focus on the artistic qualities of this unit, but rather its functionality. It does what I need it to do, but I gave four stars instead of five because I feel like it could be better in some key ways.PROS:This unit powers my Klipsch RP600M II Passive bookshelf speakers with aplomb. It easily drives the two speakers and the analog volume knob is a really nice upgrade from the software controls. Very tactile. The speaker mounts are large and sturdy. Perfect if you're like me and like to use banana plugs. It's also really easy to set up, and has been in use non-stop for several months now. I needed better audio quality for video editing and this powers the passive bookshelves pretty much perfectly, as far as I can tell. I'm understand that both the speakers and the amp have a warm sound. Honestly, I don't care to judge that. For now, this thing allows me to have far superior audio quality to what I had before, at a pretty decent price. And it easily drives these small bookshelves loud enough to bother everybody in the house. I almost never go above roughly 25% on the volume. An added bonus of my system's newfound clarity is that lower volume listening is more audible than it was before.CONS:It has been mentioned before, but I'll say it again, the power switch is in a terrible place. it sits between the power cable and the aforementioned speaker ports, which means reaching and searching for the power every single time I want it off or on. Along those same lines, this would do well to have a 1/4 inch jack for headphones, but the least they could do is put the 3.5mm jack either in the front, or on the side, but it's also in back. So every time I want to switch to headphone listening (which is often, since my wife and I sometimes work from home on the same day), I have to go searching for that jack, pick the whole unit up, turn it around and plug it in. I even thought that I'd get around this issue by plugging an extension into it so that I wouldn't have to go behind it as often, but no. There's no output selector, it just automatically defaults to headphones whenever anything is plugged into that jack.So that's it, the annoyances are...well, annoying. But I can live wit them. For the price, I still say this is a pretty great solution for my needs. But with those few changes it could be practically perfect!
