## Description

desertcart.com: Nobsound B100 Bluetooth 5.0 Tube Amplifier USB DAC Coax/Opt Integrated Power Amp : Electronics

Review: This is an impressive unit - I recently purchased the Bluetooth audio tube amplifier and I have to say, it exceeded my expectations! The sound quality is simply amazing, and the tube amps add a warmth and richness to the sound that gives my music a whole new dimension. The Bluetooth connectivity is seamless and I can easily switch between my phone, tablet and laptop. The sleek and modern design fits perfectly in my living room and the sound quality is unparalleled. The tube amplifier provides a warm and rich sound that really brings out the nuances in my music. The Bluetooth connectivity is seamless and makes it easy to play music from my phone or laptop. I also appreciate the quality input options that allow me to use it with my record player and other audio sources. Overall, I highly recommend this product to anyone who wants a high-quality audio experience in their home. 5 stars!"
Review: 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!

## Features

- With 5 kinds of analog and digital audio input (Bluetooth 5.0 / PC-USB / U-disk / Coaxial / Optical / 2 groups of RCA), compatible with almost all audio devices such as MP3, phone, tablet, computer, TV, CD players etc. U-disk input supports lossless formats such as APE, FLAC, WAV etc., easy to enjoy HiFi music.
- Multiple audio outputs for different devices: besides speaker output, add 3.5mm headphone jack out to improve sound quality for headphones, and a low frequency output is specially designed to connect active subwoofer to build 2.1 channel audio system and strengthen bass sound effects.
- Combined design of tubes and transistors: using 6P17A as preamplification, the sound is clear, warm, smooth and delicate with high fidelity. 2PCS Toshiba C5198 and 2PCS 1941 triode for power amplification, each channel can output 25W, easily to drive all home passive speakers.
- Vintage looking specially with VU meter: exquisite black panel matches with retro vacuum tubes and VU meter to dynamically to decorate home desktop space. With independent function buttons and input indicators on the top panel, easy to use, very suitable for home and desktop audio system use.
- 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.

## Questions & Answers

**Q: Bass and Treble control?**
A: No, but I use a small stand alone Schitt Loki that offers 4 bands of equalization. Its better than just bass and treble.
I find too it adds a touch of more clarity to the music.
Good luck, its a wonderful amp for the money.

**Q: Power consumption seems too high? 250 watts? Idle or when in use?**
A: Hello. Its the maximum power consumption. The actual power is dependent to the volume and speaker you use. This device won't consume more power than other similar amplifiers.

**Q: Is it easy to find tubes for this in the future?**
A: Yes, it is a tube available directly from Nobsound. They are quite special tubes, that sound very warm, rich.

**Q: Can it be used as a preamp via its 3.5mm output?**
A: Hello. Sorry it cannot. Its SUB output is only for active subwoofer and its 3.5mm output is only for headphones.

### ⭐ Faulty item, NO SELLER RESPONSE
*by J***E on January 7, 2024*

I have it hooked up to two Polk audio RC85i and it sounds great. I recently bought an active edifier 8in sub and when I connect it to the sub out I get a loud humming sound. No audio at all it doesn't play any bass. I tried Bluetooth, RCA into my phone and RCAs coming from a audio techinca record player. All produce the same hum without any audio at all. I then connected the same exact set up to a Fosi Pro amp and it plays perfect. ****UPDATE***** I reached out to the manufacturer of this item and haven't gotten a response in over 2 weeks. This is clearly a faulty item. The 80$ amp I tried in comparison sounds the same if not better and has a functional sub out. I have hooked this up to a hybrid tube amp that I paid 120$ for and it sounds awesome. This amp is honestly over priced and the QC is not there. The tubes also came slightly bent so I would look elsewhere if you're looking for a sleek setup. The esthetic sold me on this item but trust that it is not worth it.
