MoondropMOONRIVER 2 2*CS43198 DSD256 Decoder 3.5mm 4.4mm AMP 32Bit/384kHz Portable USB DAC Amplifier

I've been on a bit of a holy grail over the last few years trying to find a DAC/Amp dongle that will drive a pair of full-size headphones in as capable a manner as desktop amp. Until now I've had no success; I listened to pretenders like the Audioquest Dragonfly Cobalt, which was horribly rounded-off at the top end; Fiio's BTR7, which never engaged musicaly, the Tanchjim Space CS43131*2, which had great dynamics, but an objectional mid/top which led to instant disconnection from the music and others, which I've just forgotten about.But, now we have the Moondrop Moonriver 2: this device easily drives Beyerdynamic DT770 250Ω, through single-ended, with desktop levels of slam, punch and dynamics and here's the biggie it drives my Fiio FT3s 300Ω (albeit via "balanced" output) better than my CIAUDIO VHP2 in single ended mode, i.e. it has the voltage to drive those 300Ω voice coils which the VHP2 just misses. Fortunately, desktop wise, I have other options to drive the Fiios to any manful level.The Moonriver 2 is quite flat to the upper frequencies of my hearing (although perceived frequency response is a highly subjective thing) and achieves this without getting in the way of the connection to the music. I've actually ordered the Moonriver 2 TI from Chenzen audio as well, as it supposedly betters this model; not quite sure how it's going to do that and I await that delivery with eager anticipation.I highly recommend the Moonriver 2 as a device which will equal and through balanced even outperform many desktop amps and do so in an elegant non-fatiguing, highly engaging, manner.

All in all outstanding sound but options and settings inaccessible via app. Upon connecting device via usb an extremely devastating static blasts through left earphone which will damage your earphones/headphones and potentially your hearing, tried different cables/ports. Unacceptable. Will return and avoid moondrop from now on.

over all build quality is super, sound little bit lower than other competitors.Moon Drop Company is a very respectable company in its products, but this time it made a mistake in the price of the product.If you love moon drop products, this product will not disappoint you.
