“ I wrote this review for my blog yesterday and wanted to post it here to shout about this really great device. Yulong makes three models of DAC. Their flagship model (D18 Sabre) seems stunning but its difficult to compare to other models that I've reviewed because it's not exactly the most elegant solution for desktop headphones. Not only is the Sabre DAC sporting beast a...” --Quadpatch
“ Let me first say that this is my first Yulong product. And while I've used many Chinese products before, Yulong stands out in its own way. The DAC section is wonderful, it just hits exactly where I want it - at least for now, considering my listening preferences (which have a...” --Monir
“ http://www.head-fi.org/forum/thread/535630/review-yulong-a100-headphone-amp See above link for my detailed review. In summary: The A100 is to amps what the D100 is to DACs. Very neutral, accurate, and transparent. It's an excellent value for the price. I docked it a star in the "Design" section because it omits balanced ins/outs, which seems odd given the...” --project86
“Intro I was approached by the Malaysian distributor of Yulong (the ShenZhen YuLong Electronics Co. Ltd of China) about reviewing the D100 DAC/headphone amp. I had previously given a relatively favorable review to the older and less expensive/ambitious DAH1 Mk II, which was sent by their China Distributor, Audiophile China. However, I gave a not-so-great review to a different product sent to...” --Skylab
“ Well I tried one of these bad boys out and immediately purchased one to match my Yulong D18. I am now selling more equipment to finance said purchase. Some people think this is a boring design, I think it is very sexy. meow. ” --Jamesdeandoa
“This review is based on matching the Mini X with Hifiman He-500 Headphones. You may be reading this review, unsure what to make of this Amp, asking how can a cheap sub $200 amp offer the power needed for an expensive Headphone such as the Hifiman He-500? If you have done your homework you will find this is the stereo amp everybody is...” --fluidz

As always, YMMV. ****NOTE**** FISCHER AUDIO MYSTIFY PORTABLE HEADPHONE AMP SPEC’S: Frequency “flatness”: +/- 0.5db Dynamic Range: 110 db Total Harmonic Distortion: 0.001% Intermodulation...” --LFF
“All i can say is this is a great amplifier for its price.. (not gonna comment on mids,low,highs because due to sensitivity of ears and would be unfair to compare at different volume levels) For those whose ears are not sensitive this is probably a good amp for you ” --OnlySound
