Hi, hifineubee,
My topic in Taiwan MyAv has raise up deep discussion between the different opinion group. That is beyond my expectation. It looks like word war. Opposite opinion persons corssed fire on each other on the subject of audio listening experience......
The 2nd hand audio shop where I found the 803S has sold out it's 800D and Sonus Faber Guarneri Momento (each pc. weighted about 75Kg with origin speaker stand consists of thick stone. The shop's selling price is NT$22.5 Wan. (around US$7,500). In the meantime, there is also one same speaker selling on MyAV 2nd hand column which priced at NT$ 190,000 by the original users (not the 3rd or 4th hands.). But the speaker color of the later is slight dark brown.
I don't know why the expensive one in the shop be able to sell faster than the much cheaper one direct sold by the user. The same model the different is the color. Generally, the sales through the owner always have better quality and slight cheaper price. Those sold in the shop usually selling with higher price for the boss need to mark up the profit and some need to send to the expert for fix first before the shop can display for sell.
I also know one 2nd hand shop in the not easy to find inner lane in Taipei. Though the shop's price is slightly cheaper than the above one. But once both shops are sellilng same model, the above one sold out faster even it is selling higher.
I heard some music for comparison in the youtube which there are many combination of audio system and music over there. The posts showing various tastes the owner have, some are awful, some sounds strange ( agaist your expectation). If you have time, you can have a try listening. With good pair of headphone you can tell the difference with easy.
