I Always dreamed of a Tube amp with Two VU Meters, ever since I was a kid. I saw the reviews (and an especially helpful video review on YouTube), and I was convinced to buy the Muzishare X-7. I paired with Polk Audio i200 bookshelf speakers and a Polk Audio 10" powered subwoofer. (These bookshelf speakers are not tiny--they don't fit upright on any bookshelf). The amp powers the i200s just fine. Sound is excellent in both Ultralinear mode (45 watts per channel) and Triode mode. I personally prefer the Triode Mode at a higher volume (which I'm told is 25 watts per channel and has rolls off the treble a tiny bit). The bass response without the subwoofer is excellent. (I add just a tad of subwoofer as a personal preference). I have never exceeded the 12 o'clock position on the volume. At 12, the amp is overpowering in a good way. There's still a lot of power left. My personal tastes aren't loud volumes, just note that there's plenty of power for efficient speakers. Highly likely, you'll have plenty of power for larger drivers that are in tower speakers, especially in Ultralinear mode. I haven't opened up the case (like the reviewer did on YouTube), but the exterior is solid quality everything! The reviewer showed quality point to point wiring with quality soldering on the inside. I have nothing negative to say about this amp. I've had it use for about 3 hours per day. Theoretically, the sound will get better as my speakers get broken in. Apparently, tubes also get a little better performance with use. (Note, they'll degrade after time, but that's probably 5-7 years away, and will need to be replaced. But, that's a known fact about vacuum tubes). My amp is the focal point of my living room. I love the look in the light. In the dark, the glowing tubes and twin VU meters are just art! Again, since the early-80s, I've dreamed of a tube amp. $1300 is a lot of money, but an incredible value for what you get, considering what boutique tube amps cost. Don't let the "Made in China" scare you on the quality. It is excellent. The biggest negative that the YouTube reviewer had was servicing (because it comes from China). I disagree. Since it's basically 1950's era technology (that is, it runs on vacuum tubes), I would argue that service should be easy to find no matter where you live. By no means am I criticizing the 1950s era technology, I just mean to say that it's relative simple compared to the most modern solid state amps.

(May 11th 2021) This has only got better in the almost 2 years I've owned it. I've swapped out 12ax7 and the 12au7 tubes with NOS 50's and the rectifier tube with a 1958 GE Copper. I also swapped out the KT88's for KT120's. (See updated photo) Is this something you need to do? The answer is no, but it has taken it to the next level. Don't listen to the very,very few bad reviews. This is on the level of Amplifiers well passed it's price. I'm a proud audiophile and I've been in this game for 40 years and heard and have had many great amp's and this is right up there with some of the best. Is this in a league with a $20,000 amp...NO but come on let's be real, but it hangs in with $4000 and $5000 ones with no problem. After 2 years of continuous play and that's almost everyday and not one issue, I'm saying again BUY IT!! You will not be sorry. Everything about this is mind blowing good!!! The build,the sound and the price. This is not your Yaqin or Nobsound. This unit is on par with Primaluna and I dare say a little better. You will not be sorry buying this or any Muzishare amp. Handmade with point to point wiring and nice and heavy. The imaging is breath taking. Warm smooth mids and tight bass and tons of air. It feels like your in the room. I play a wide range of music from rock,jazz,classic country and everything in between. I was listening to a recording that was recorded in a old cathedral in Germany and it took me there, I could almost smell it. I love this amp and you will also!!!! Get it before the price goes way up!!!!

The media could not be loaded. I spent a couple of weeks looking at and reading about Chinese tube amps after giving up on trying to find a good used vintage one for fear of what lurks in 50+ year old circuitry and realizing that modern materials/components are much better than they were in the 1950s-1970s anyways so unless I spent alot of money on an old one that has been completely rebuilt with modern components then it really wasn't worth it for any reason other than nastalgia. I like nastalgia and all but I am a practical man so I decided to get something new without spending more than $800. While shoppinhg around I quickly realized that my price cap was unrealistic for the feature set that I needed. It had to be: Class A-B with an ultra linear/triode switch and a phono preamp stage and of course power output, distortion, signal to noise ratio etc. were also being taken into consideration and of course it had to have at least one analogue meter. The remote wasn't a requirement but it is quite the luxury on an amp such as this, I would not have gotten a remote had I bought that Citation II I was eying on Ebay. After a lot of searching I found the X7, it looks great with a retro sort of style as if it were made for people like me who are craving whatever it was in the sound and presense of the amps we experienced when we were younger. The experience of hearing the sound, feeling the warmth eminating from the cage and witnessing the equally warm orange glow of the tubes and of course the glowing dancing meters. The experience was enhanced by me only being 3 ft tall at the time so the glorious tube amp was almost at eye level so could feel the warmth on my face and not only on my hands. End tangent. The bottom line is the X7 was the least expensive one that met all of my requirements and much to my delight it looks fantastic as well. Upon reception I was immediately impressed by the quality feel of the amp. The feel of the weight of sturdy metals. The knobs feel nice to turn, there is a good amount of resistance which give them a quality feel. And of course, it was very well, no, it was meticulously packaged as something like this should be. The sound at first was good but a little raspy on the high end, after the 100 hour burn in period I couldn't stop smiling at the sound. It wasn't what I would consider perfect but it was very good, good enough to put a grin on my face. Plenty of power for my JBL Es90 s, sounds really good. I didn't like the port noise at the low end of the es90 s though so I added a powered sub. I didn't want to lose that elusive and magical tube sound on the low end so I bought a speaker to line level adapter from Crutchfield so the SA-1000 class ab amp powering the sub is amplifying the wave form being output by the tube amp and not the signal before it is passed throuth the tube preamp and amp stages. I think this is a good compromise and now the system is very loud if I want it to be but volume isn't the point of an amp like the X7, I wan't quality, I've had plenty of quantity. I didn't like the sound of my klipsch 3.2 s with this amp although they were very loud all by themselves since they have an spl of 94. My JBL studio 190 s sounded the best and there was no port noise to worry about but with an spl/sensitivy rating of 90 I had to turn the volume knob up almost all the way to get it to be what I consider to be enjoyably loud when I want to crank it up a little bit. No bleeding ears or anything like that, lol. The phono input sounds ok but not as good as I hoped and not as good as my 1992 Onky preamp. I am hoping that some future tube upgrades will resolve the issue. The upside though is that the preamp sounds excellent hooked up to the SB AE-9 in my PC. In fact, my 24 bit vinyl rips sound so good now on the X7 with no equalization whatsoever, (I can control the low end with the sub levels) that I wonder if I even need to play my records anymore. I still will though either way. The headphone output does not sound very good on my AKG K7xx headphones, I'm not sure if it is an impadance issue or what but the sound is very flat and needs heavy equalization for me to get any kind of good sound out of it. The headphone output and the less than excellent phono stage are the reasons why I only gave 4 stars but for the $1500 I spent on the X7 I don't think I could have gotten anything better and now I have a good excuse to get me a nice vincent phono preamp if I so desire. I needed an HDMI switcher for my set up. If you need one too I recomend this one. https://www.amazon.com/dp/B0865Q2MTG?psc=1&ref=ppx_yo2ov_dt_b_product_details I recently hooked up my vintage Onky preamp and EQ to use in the phono stage and it is sounds much better, even with the new tubes.
