Hi all,
This is a review (of sorts) for a "Clone" amp inspired from the legendary Accuphase E-406 (which is actually an integrated amp that Accuphase released back in 1993?), this clone version is just the power-amplifier part of it. I acquired it just over a week ago from Aliexpress (HiFi vendor in Shenzhen, who was easy to communicate and deal with). I was encouraged to seriously consider one of these clone amps from watching "HiFi Zone" youtube channel... the guy reviews a lot of Aliexpress-sourced HiFi gear. With the tariffs happening fast, I pulled the trigger and luckily the vendor shipped it via DHL-Express, so it arrived to in just 1 week after order confirmation.
The package came in fully intact, zero damage.. it was heavy, almost 50 lbs (amp itself is 21kg according to the manufacturer specs). Opened it up, here are some close-up pics:
Specs/highlights (from the AliExpress product page):
1: The whole machine adopts 24 German IXYS Essex MOSeld-eect high-power transistors, each with a current of 30A and a power of 450 watts, far exceeding that of Toshiba Ansemy high-power transistors
2: Adopting factory customized 320000uF capacitors for super large pools, far exceeding similar products
3: Using 850W full strip steel sheet, large diagonal iron core, pure copper winding, far beyond the comparison of ordinary transformers
4: Using the latest American technology, third-generation AC power purication technology, to isolate noise from the source in the mains
5: We use the latest generation power supply for soft start to ensure stable operation during startup. Our power supply has a very large capacity,
which is not comparable to ordinary power amplifiers. Charging a 320000 uF capacitor can instantly reach 160A
6: The use of a completely symmetrical and independent power amplifier board with left and right channels greatly improves the separation of sound
7: Using NEC signal relay purely mechanical to switch sound source signals, rejecting sound coloration, using 2 Omrons 16A ultra high current relay serves as speaker protection, with separate left and right channels for protecting speakers
8: Using 2 sets of speaker terminals for output, the speaker can be split into two lines, with Group A connected to mid high frequencies and Group B connected to low frequencies, fully tapping into the potential of the speaker
9: Using Taiwan pure copper speaker wiring terminals can greatly improve the damping coefficient of the amplifier and enhance its strength
10: Adopting dual header dynamic display, retro and charm coexist, and adopting logical calculation method is more natural
11: The all aluminum chassis showcases a high-end atmosphere, with an iron frame inside to make the overall chassis more sturdy & eliminate resonance
Technical parameters:
* Rated continuous output power (20HZ-20000HZ)
* Pure Class A: 60W/4 ohm output
* Pure Class A: 30W/8 ohm output
** Class AB: 320W/4 ohm output
** Class AB: 180W/8 ohm output
* Frequency response: Continuous rated output: 20-20000Hz +0 -0.2db
* 1W output :05-160000HZ +0 -3dB
* S/N signal-to-noise ratio: 120dB across the entire frequency band
* Input impedance: 40K (balanced input), 20K (RCA input)
* Input sensitivity: 0.87V rated continuous average output 0.11V output 1 watt power
* Distortion of 0.005%
* Amplification factor of 28dB
* Overall size: 430W × 160H × 430D mm | Net weight 21kg
Here is my the diagram of my setup:

Thoughts:
Prior to having this power amp, I was running Emotiva BasX A1 monoblock amps. Note that I also recently just acquired the Emotiva Amps, just a week prior to ordering this clone amp. So, my Emotivas are also barely broken in... so again, comparing both is pretty fair, given that they also have similar power/wattage numbers & amp type.
This is purely based on how they sound to my ears... I rate them in these following points (70% music & 30% movies):
* Power Delivery: it seems that both are equally effortless when driving my Martin Logan Source Electrostatics... bass is deep, low, punchy, etc... mids are clean & realistic... highs are very clear & detailed
* Dynamics (or Dynamic Range): BasX A1 = 8/10 | Musmys = 9.5/10
* the clone amp has a higher-end sound with remarkable clarity, detail, transparency... the soundstage is wide & deep, and 3D-ish/holographic. The Emotiva A1s also has those qualities, but the Musmys amp is on another level... at least to my ears! LOL
So in conclusion... if I ever need another amp, I would NOT hesitate to buy from this Chinese brand "Musmys", particularly their Accuphase clones. They look fantastic (I love the analog VU meters) & sound is just fabulous! Too bad tariffs is going to make them unavailable for the time being, just really glad I got one just in time! Not bad for just over $700 shipped to my door... this has been one of the best buys I've done for a hobby, completely felt good about it. Hoping it holds up & lasts a long time!
