Q: I got a loud hum with this T7 phono preamp. A: For the hum noise, in the beginning, we have to clarified that all phono preamps have a certain of background noise. It won't be loud, while a little loud is just normal. Turntable is a kind of analog players and cannot be compared with digital players in this respect. Besides, there are many factors which may lead to bad noise.
To find the right reason, you need to do some tests and here are some instructions. Reason A: T7 isn't connected to ground well. This is the most common and unnoticed reason. Please test it following the steps as below. While the device is playing music, picking up the GND copper part of T7 with your fingers. For this issue, we prepared a 3m wire in the package for you to solve it by yourself.
Just use it to connect the GND with any large mental item in your home like windows or mental tables. There is a possibility that T7 may not match with some digital amplifiers well, which may lead to very loud noise. And found that.Intercessory prayer book pdf

Perhaps this is because so many people are moving to digital sources and components and everything sounds a bit too clean and controlled.
Sometimes you might be craving some harmonic distortion to dirty things up a bit, or want to add some warmth to those analytical headphones.How to program old comcast remote
Maybe you just want some cool glowing lights on your desk or you simply need to make your music louder. Well, this little hybrid tube amplifier can do all that. We are devoted to design and research of hi-end level of audio equipment under our own brand name Nobsound and Douk Audio with our intellectual property rights. We are striving to build classical extraordinary audio equipment with cultural connotation and propel national audio brands worldwide and pace up with the rest of the world.
All opinions and observations here are my own, based on my experience with the product. This is a hybrid amplifier, meaning it uses the tubes for pre-amplification and transistors for the actual audio output. This allows you to get a taste of tube sound while keeping the costs lower for consumers and the benefits of solid state like better bass control. Similar to the NSE, this amp is nicely machined and put together.
On the gold coloured front are the 3. These incremented movement dials feel great but they do make precise volume adjustments a little more difficult. On the top of the black metal case are the two 6J9 tubes that simply plug into the provided sockets.
They fit tightly into the sockets but are easy to install and remove with some care and gentle wiggling. There have been a few mentions on the internet about the tube ringing sound that sometimes occurs if you bump the amp or the desk. I have experienced this myself but only with sensitive headphones and IEMs. With the ohms Beyerdynamic Amiron Home I was not able to reproduce the sound no matter how hard I tried and it was the same with the T1 Pro.
This little guy adds some warmth and fullness to the midrange while retaining detail and separation from the source. Treble and bass remain well extended on both ends. With harder to drive headphones like the T1 Pro the NSE can add some extra punch to the bass and a more controlled sense at the low end.
The unit gets a little warm while in use but its certainly not what I would call hot. The sound can also be customized by rolling different tubes.
For the purpose of this review I stuck with the original 6J9s. The Nobsound NSE sounds better than it should given its budget price. The only drawback I can find and this is just personal preference is the input being located on the front panel. It becomes a problem for people real fast. Been poking around your site too. Very nice reviews. Will do.
Read one review that said the tubes were all for show and did nothing to the sound. They said it was all solid state not really a hybrid. There was actually some discussion about that here a while back but somehow those messages were lost. I will repost the answer I got from my friend who is the lead engineer of Phatlab Audio:. It is just less effective. A good example is those new preamp from Audio Research whose tubes are also configured as an output buffer instead of voltage gain stage. The difference is that when tube acts as gain stage, it will output more unique distortion, said 2nd harmonics, which might be what people usually say tubey sound.
On the other hand, when acting as a buffer, there is no voltage gain, so less 2nd harmonics output and less tubey.Audiophile General. I heated up the solder joints in the remote, still no worky. The unit works. There is an obvious wiggle and scratchiness to the headphone jack. The sound is fine, but I need more time to put the product through its paces. I am also still getting used to the neq crossovers I put in my Sansui SPs notice I didn't mention "burn in".
I sent an email to Douk asking for a remote replacement, and they said, "No problem, just confirm you phone number for shipping safety. I will update on the sound soon. Assuming I get a working remote, it is at least a fun toy that allows all common digital media including BT functionality to my "dad" Hi-Fi. The BT antena works better than my old one. I can say that the BT signal sounds less, err, loss-ish, just streaming music via BT.

I still have to call this a BT input with tubes, not a tube pre with BT. Jan 16, Did you noticed any improvement in the sound quality? I wonder if I should try to get a cheap tube preamp to see if it changes anything in my set up, but I fear that it will be a wast of money unless I go for a expensive one.

Turned it on for the first time, Let the tubes warm up for about 10 minutes before playing some jazz music on a pair of Mission Cyrus 's. This thing sounds really good for the price. It got here 2 days before what was listed on Fedex.

I wanted a preamp to connect my iphone to an old 70's tube-type stereo. A fusion of old and new, I guess. I liked that the unit has tubes and it was small yet had separate volume, treble and bass controls. Hookup was a no-brainer; connected the included power supply to the back of the unit along with the mini plug earphone size jacks for input from phone and output to the stereo and I was in business. The unit added just enough volume to make listening more enjoyable while the treble and bass controls smoothed out the sound.
And who can beat the look of glowing tubes!? The sound is very clean but I noticed the low frequency doesn't go low enough for a extremely tight base booming not tightthe treble is perfect, the mids are great.
I can't comment about its longevity since I had it less than 24 hrs, I am already thinking of buying another one for my computer sound system. I would definitely recommend this preamp. I am using this small pre-amp to drive a dyna sca35 spare inputs, as the dyna except for the phono pre-amp section is basically a st power amp. This little unit works great, it vastly improves the high frequency response, as I am using fairly long cables from the music source.
Highly recommended. Versatile unit use with amp of sufficient gain. I like with walkman tuner plugged in to drive small tube amp. I suspect cathode follower circuit excellent for the low noise factor. Gain equals noise, this is great compromise. Tone section useful and no more muddiness than any other preamp with tone.
This Nobsound preamp is wonderful. First, it's tiny! But, it really warms up the sound by putting tubes in the preamp stage even with a solid state final amplifier.
