the Phonograph CD Player CD player (2007) yong jieyu + ama A 2 day workshop with Joris Laarman. The aim is to analyse a product in its history and function and redesign it. A CD player was disassembled and the components rearranged to suit the layout of a phonograph. The speakers are put below the trumpet loudspeaker for amplification. The wooden box is made slightly more spacious then the electrical PCB board needed to achieve bass resonance. The laser pointer is shifted to the top allowing the spin of the CD to be clearly shown. By bringing back a familiar nostalgic form of a phonograph, the design seeks transport the user back to the golden age of phonographs in early 1900s where sound broadcasting had a magical feel. http://www.jieyu-design.com/producthtml/cdplayer.html http://uk.gizmodo.com/2007/05/29/phonog ... _your.html

Amplifier đó bác -làm mát bằng dầu (nhưng làm lò sưởi tốt). Công suất 1500W lận (có cho em cũng chẳng giám dùng, vợ em đè cổ ra đòi tiền điện) Description (Handcrafted De Longhi Ultimate) In the rarefied world of upper crust HiFi, there are ultimate truths accepted by the cognoscenti. One of those truths is that power, very high power, is a very good thing indeed in amplifiers. Another well held truth is that inefficiency in components is a certain route to the best and most pure audio experience. In this pair of mono amplifiers, I have attempted to combine both those attributes in a compact package. Switchable power levels on each unit allow for up to 1500 watts a channel. That's not chopped liver as power numbers go in anybodys league. Further, the units boast a full zero efficiency. For those that appreciate true low efficiency operation for the glorious thing that it is, this is no mean feat. Delving further into the psyche of the true audiophile we find the matter of oil. Small, oil filled capacitors of the vitamin Q type and imitations from Russia and other sources boast an oil content of a drop or so per capacitor. A drop or so and audio Valhalla is reached complete with Brunhilde in the brass brassiere. Going one step further, these units carry quarts of warm, honey rich oil to tailor the fine nuance and delicate timbre prior to its arrival at your anxious ears. I conducted two independent experiments to verify the benefits of the oil in the circuit. First, I constructed a pair of these using a pair of water filled baseboard heaters as a basis. While not bad, they were thin sounding in comparison. In retrospect, that was to be expected, oil has a heavier, deeper body after all and if one desires the warm, liquid sound in ones living room, what could be better than warm liquid to effect the desired result? Secondly, I drained all the oil from the crankcase of my auto to see the effect, if any on my auto system. As I tooled about town I noted that at first, the noise level went up rather high. As I was waiting for the tow though, I had time to reflect on the sound with a silent backdrop. Rather good I thought. Now I do realize that the asking price may be a bit stiff for some in these trying economic times but a lot of that is simply a reflection of the oil market. That is simply something out of the control of humble crafters of fine audio equipment like myself. Should the cartel relent my pricing structure will react straightaway. This is only the start of the real adventure. After these sell I intend to craft a set using three of these units per channel. At a hearty 4500 watts a side they should please the most discriminating and cultured listener while offering a somewhat decreased efficiency due to the Triode mode of operation. All advances do come at a cost and advances in the art are hard won by daring pioneers. If not for pioneering efforts such as this where would the audio art be today?As these are rather bulky to pack and ship, no overseas sales please. I must admit that I will dearly hate to see these go as they have become almost part of the family in the many years that they have lived with us, however, no sacrifice is too much to make in the interests of advancing the audio arts.
