ViVo X5Max VS Lenovo Vibe X3. ----------------------------- If you want to use a smartphone as a smartphone like playing games, multimedia stuff, watching movies in VR headset, etc along with a supreme sound quality that misses the X5Max by a whisker, get a Lenovo Vibe X3.
I will be perfectly fine with Vibe X3 which uses the same high-end ESS SABRE ES9018 DAC of Vivo X5Max.
But Lenovo like other manufacturers do not have access to Vivo exclusive ESS SABRE ES9601 op-amp for critical I/V conversion.
So what Lenovo (or rather Motorola) did was clever they used the best op-amp available in the market, the same Texas Instruments OPA1612 (used in X5Max as headphone amplifier) to perform the current-to-voltage(I/V) conversion.
But to improve performance and keep it close to ES9601 op-amp they used a OPA1612 per channel (differential configuration) rather than justy one for both channels (single-ended configuration). Hence two OPA1612 are required for the stereo I/V conversion rather than just one.
Further Vibe X3 uses the third OPA1612 just as a headphone amplifier just like X5Max.
Lenovo was definitely inspired by Vivo's HiFi 2.0 architecture in X5Max and Vibe X3 is the result. It uses the same ESS SABRE ES9018 DAC and three OPA1612 op-amps in its audio path.
Vibe X3 attained a measured 120dB SNR -103dB distortion (fractionally less than X5Max's -100dB) and an high output voltage on +0.9518 volts over headphone jacks.
These are signs of a true HiFi oriented smartphone. Apart from similar audio performance over headphones, Vibe X3 will obliterate X5Max with stereo in-built speaker performance.

ViVo X5Max v.s. Lenovo Vibe X3 --------------------------- Subjectively speaking both are equally loud on same headphones, maybe Vibe X3 a fractionally louder.
I believe X5Max having access to the exclusive ESS SABRE ES9601 op-amp for ESS SABRE ES9018 DAC have a slight edge.
But then you are splitting hairs as both uses the same DAC in different hardware architectures having their own strengths and weaknesses.
X5Max having slightly better separation, transients, plucked strings of guitars are better illustrated and high frequency transparency is second to none.
The Vibe X3 on the other hand have a slightly more authoritative bass mids are more thick and mellow and male voices are slightly better put than X5Max.
Female voices sound slightly better in X5Max. I will say Vibe X3's sound signature is somewhat in between the mellow-ish X5Pro & sharp-ish X5Max.
It is very hard to choose between the two and will ultimately boil down to personal preferences. Having said that Vivo & Lenovo have both done a stellar job in X5Max & Vibe X3 respectively and they are currently second to none in audio department.
If you love complete separation of instruments and the openness in sound signature go for X5Max else if vocals is your preference go for Vibe X3.
Apart from audio, the X5Max have more up-market feel with slightly better built quality over Vibe X3.
The 5.5 inch 1080p Super AMOLED display of X5Max is superior to Vibe X3 in terms of both color reproduction and vibrancy.
Battery backup just makes up for a day in X5Max as it is the thinnest phone in the world with just 2300 mAh juice.
Both the smartphones have excellent call quality, just like Motorola's CrystalTalk.
