Let's face it. There are many very nice players to market now which perform very well. Think Hifiman HM901, Astell&Kern AK240, iBasso DX100, Fiio X5, Calyx M etc. But in many cases their operating systems are a pain in the ass. They may be glitchy, slow, use a confusing user interface, struggle with different types of file formats or take forever reading a card. Here the PAW Gold is one of the fastest guns from the East. Even its operating system is faster than the no-screen Altmann Tera Player. No joke. Although its GUI is not as fancy as the iPod's or that of the AK series, it causes zero confusion to the user. Imagine a DAP which powers up in 2-3 seconds and shuts down in 1-2 seconds. Imagine a DAP which starts to play files three seconds after you inserted a fully loaded 128GB SD card. Imagine a DAP which will play all of your DSD files and run for 8-9 hours; which has 5ps of jitter. Can you say splendid like winning the lotoo?
The PAW Gold consists of over 600 components and parts.
"As a reference music player, the PAW Gold has a strong heart in the Analog Devices Blackfin 514 DSP core processor with a specially designed real-time OS. It uses a Burr Brown PCM1792 DAC chip for extremely high dynamic range of 121dB with only 0.00058% of THD+N on the headphone output."
"The digital input filter separates the incoming signal into six upper bits and 18 lower bits. The six upper bits are converted to inverted complementary offset binary ICOB code. The lower 18 bits associated with the MSB are processed by a five-level 3rd-order delta-sigma modulator which operates at a default 64fS. The 1 level of the modulator is equivalent to the 1 LSB of the ICOB code converter. The bit groups processed in the ICOB converter and 3rd-order delta-sigma modulator are summed to an up to 66-level digital code, then processed by DAW data-weighted averaging to reduce noise produced by element mismatch. The up-to-66-levels DWA data are converted to analog in the differential current segment section."
"The LME49600 headphone driver delivers powerful energy to support a wide range of headphones with 500mWpc@32Ω whilst a high/low switch adjusts gain to complement different requirements."
Let us see what the PAW Gold has got for us,
Packaging and Accessories: The PAW Gold unit arrives packed inside a outer cardboard sheet, in which a strong plain black cardboard box is contained. The box has magnetic locks everywhere, and can be lifted off to reveal the multiple storage compartments, in which all the included accessories are present. Necessary amounts of accessories included in the package, and again are made up of good quality. I can confidently say that Lotoo has done packaging in a very premium and extravagant fashion.
Design and Build: The PAW Gold has an excellent build quality.
The entire shell is made up of high quality duralumin metal. Duralumin is a very hard and tough type of aluminium used to build aircrafts. The DAP is painted with matt grey colour, which ensures PAW Gold is not a fingerprint magnet. The PAW Gold Is heavy in weight owing to its robust build, but still it can be comfortably operated using one hand itself, since the PAW Gold is actually a small DAP, it just appears large in pictures.
On the front side, four navigation buttons (Up/down Left/Right) are present, along with a central select key. The navigation buttons are used to navigate songs, or forward/backward operations depending upon the situation. A select key is present in the middle of navigation keys, and is used to select or play/pause the songs. Buttons are well designed, and operates flawlessly. PAW Gold has a very ergonomic build, which means everything is placed at right places and is comfortable to operate.
Volume knob, navigation and power keys are 24 karat gold plated. Hence comes the name ‘Gold’
Volume controlling is extremely fine, and works very well with IEM’s and headphones. One can achieve even minute attenuations in volumes without any issues. Volume switching is silky smooth and very gradual, which is a big plus especially sensitive IEM’s. Display screen is good enough, though screen clarity or screen resolution is not impressive, but still it does the job just fine. (This is expected almost of all DAP’s)
File button has the function of browsing the folders on the SD card. Setup button takes us to the settings option for this DAP. List button leads the user to the song playlists. APE/PMEQ button takes us to the hardware coloration and equalizing options. The button named as ‘Fn’ is a key for which we can define the function of our choice. Power button (Press and hold type) is present, with a white coloured breathing light around the button itself. This button is used to power on/off the DAP.
On the left side, a charging port is present, to which charging jack of the given charger has to be connected to recharge the battery of the PAW Gold. High speed USB 3.0 port is also present just above the charging port. This port only handles data, and charging cannot be done with this port via USB.
On the right side, there are no controls present.
On the top side, Outputs jacks are located. Headphone output, Line output both are present in 3.5mm format. These jacks are well built and implemented, and have a good feel to them. A sliding lock button is present, whose function is to lock down all the keys once lock button is activated. A sliding gain switch with Low/High gain setting is also to be seen.
On the bottom side, a full size SDHC/SDXC card slot is present. The slot operates smoothly without any hitches. Insertion and removal of card is fairly easy, with just a simple push. Rubber flap is present to cover up the slot from any foreign material.
User Interface: The current firmware version is V184.108.40.206, and is upgradeable as new versions are released by Lotoo. Startup and shut down happens within just 3 seconds, which makes PAW Gold quite fast in operation. The firmware itself is fast, responsive to browsing and switching operations. No hanging or slowing down whatsoever. I sometimes wish there should be improvement in screen resolution, because as of now the fonts appear pixelized.
Setup key opens up the settings and other options. This DAP is DSD capable, along with one can change many advanced settings like layouts, key speed, DSD settings, playing settings. Volume controlling is available even on Line output, and custom gain can be selected.
The battery indicator accurately calculates the actual amount of battery power remaining, and has stable readings. One undesirable thing I notice about PAW Gold is that, it gets fairly warm during playback. But during battery charging, there is no such issue noticed. Battery life is fairly good. As for me, the battery lasts for about 7 hours, which is quite good. The battery capacity of PAW gold is of 6000mAH. The battery has to be charged by a 5V 2A adapter, and is included in the package. Charging time using this adapter is around 2 hours.
Overall, the firmware is simple, is fairly fast to flip around, is customizable and is quite reliable and stable. But there is room for improvements.
Sound: As for the most important part, the PAW Gold is highly resolving, transparent, Neutral and Detailed sounding with excellent spacious & expansive yet accurate sound stage. Another thing to mention about this DAP is that, there is absolutely no ‘lag’ and sound response is ‘quick’ and ‘fast’
Dynamics are superb, giving a circular spacious sound. Soundstage is airy and spacious, but in a natural and realistic way. I am clearly able to differentiate between FLAC and 320kbps MP3 for the same song. Instruments separation is great, and there is a lot of room and air between the instruments, which again contributes for an immersive experience.
The PAW Gold has hardware controlled equalizers and preset colourations. These are called as ATE/PMEQ, which upon selected, perform their tasks very well. But I feel, to enjoy the ultimate transparency and neutrality of the source, one should always turn off colorations/equalizers.
Considering its neutral sound quality, it can match up with any genre and any headphone without sounding bad in particular. The transparency is really appreciable. PAW Gold is very resolving, transparent. Due to its resolving nature, it is unforgiving towards poor recordings. But feed it with good recordings, it can churn amazing sound quality.
Output power at headphone jack is very good and is sufficient to drive any and all IEM’s and also to drive most of the headphones, to extremely loud listening levels, I always listen to volumes below 60 on IEM’s and below 110 on headphones. Noise floor is audibly dead silent and pitch black. I could not detect any audible disturbance in any form from the PAW Gold. EMI pickup is completely nil, along with no pop sounds on startup or shutdown, which is really appreciable.
Comparing the PAW Gold with HiFiMAN’s HM901, I feel the competition is head-to-head in terms of sound quality as well as build quality. The HM901 is relatively warmer and intimate (depending upon card used), otherwise as detailed. Whereas the PAW Gold is very transparent, neutral, and relaxed. (Of course, we have to remember that PAW Gold costs about 800$ more than the HM901)
However, PAW Gold wins hands down in ergonomics, portability factor and output power. The PAW Gold is way smaller than the HM901, more comfortable to hold and operate, along with support for high speed USB 3.0 connectivity. It also has a more ‘simple and user friendly’ firmware than the HM901. Battery life is also marginally better in PAW Gold.
But one cannot deny the HM901 simply carries a sheer value aspect with it, and if right amp card is matched up, then the sonic quality & value aspect of HM901 will be preferable for many.
Conclusion: Although Lotoo is an unfamiliar brand in the audiophile world, The PAW Gold is an amazing and stellar DAP. It offers top-tier transparency, resolving power along with a greatly neutral sound quality. The sound quality is phenomenal and Build quality is supreme. The sole drawback I find is, it offers lesser price/performance ratio compared to the HM901, which is priced around 1200$. As you go higher up, Law of diminishing returns applies.
1) Build Quality: The PAW Gold has a top notch and extremely good build quality. absolutely no compromise to be seen anywhere. Battery life & UI too are pretty decent and reliable.
2) Sound quality: Top-tier sound quality and is very neutral, detailed, and expansive. Ideal sonic qualities for a DAP, and one of the best I have ever heard.
3) Transparency & resolving power: These deserve a special mention. Transparency and resolving power in the PAW Gold is simply one of the finest available in sub 2000$ category.
1) Heating: The PAW Gold’s chassis warms up little bit during song playback. I did check up with other members, it seems like the warming up is not really an issue. Even the HM901 warms up to this level.
2) Value: The PAW Gold is priced around 2000$ and considering the pricing of many of its rivals, I feel this one might posses a little lower price/performance ratio.
