The original post describes the comparison of a modded Zhaolu vs. a Benchmark DAC1 and Lavry DA10 made by three people and posted on Head-Fi. After summarizing the findings, the OP states he doesn't believe the comparison was shilling. He says this level of shilling would be very difficult for Zhaolu to "buy" anyway. Then the pricing structure is listed, and the point made that the total is still less than half the price of a DA10.
Responses include:
Surprise at the high cost of the base Zhaolu, US$180.
Curiosity as to the specific mods done to the Zhaolu. Several people want to know what the mods were.
In post 14 the OP states that a DAC that can beat a DA10 at US$400 is a great value, no matter if modded or not. He wonders if Zhaolu would directly sell an already modded unit.
Post 16 says there's some uncertainty, since the mod parts cost a lot more than prices in China.
In post 37, the OP states the point is not that it's a Zhaolu, it's that a US$400 modded DAC can compete with the highly regarded US$1000 Lavry DA10.
Post 38 asks the OP to look into what the mods were.
Post 43 is the contact info for the HK-based Zhaolu distributor, Wai Wai Valve, and says it seems many foreigners are buying from him.
Post 47, the OP is asking for Ferbose, apparently the same Ferbose who is a member here.
Post 48 says if the comparison was fair, it means stock Zhaolu units made too many compromises.
Post 51 asks is there such high precision, regarding the Clock upgrade, 2PPM $70.
Post 53 the OP is asking for Ferbose again.
Post 65, goto2003 (apparently a member of Head-Fi) states that he bought a unit for $250, with only the power supply upgrade, because the latest info is that the clock upgrade doesn't do anything.
Basically, the guys at Erji.net are wondering what the mods to the Zhaolu were that allowed it to "beat" a Lavry DA10.
