2011-02-09 Quasi-Higi end from China
It was definitely cheap, but it came with one cracked tube out of 10.
I wrote to them that I had problem, along with clear picture for a week ago. There is no response yet.
China is great, but it may be very far a way that light-speed e-mail takes more than a week.

2008-06-21 OOMSAP, another story
One ESL-63Pro is now located at the middle of ESL-57 pair through channel mixer and 6dB/Oct LPF at 200Hz. AWCS only works below 50Hz (12dB/Oct @ 50Hz). I tried to adjust each level and crossover frequency without any test equipment, and that was so far successful.
I borrowed measurement microphone with a microphone preamplifier and 24bit/192KHz ADC.
The measurement result is unusual. The response is +3dB@100Hz, +5db@63Hz, and +5dB at 16Hz. That is practically flat. However, it is flat up to 16Hz. Connecting the cannon shaped blower makes obvious difference even though I barely hear its sound by itself, except rattle sound from some furniture at very high volume (but yet barely heard). The OOMSAP does not know the reason why the air vibration far below the audible frequency because OOMSAP is stupid.
I might be one of the most stupid audiophiles in this planet.
I have used a pair of elegant Quad ESL-57, designed more than a half of a century ago in United Kingdom for domestic use, supposed to distribute sound from the air... Its sound is so transparent and clear, sounds from air.
THE AMERICAN BOOM BOX, THE REAL THING has been connected. One of the most tempestuous box was left alone in the very middle of the British gentlemen. This stupid combination make some progres ssomehow. They worked togather to make the sound fully bodied with elegant suits.
Second mistake happened a few minutes ago. Another American pipe organ thing ; BOSE AWCS-1, which was listed in an auction site, is now located at the back of the old gentlemen. That pipe had been situated in a club house in a city, looked down considerable number of auditory damaged dancers, and contributed to reduce their acoustic ability, for years. That killer pipe came into my place, kicked out the boom box completely away, now rests peacefully at the back of the British gentlemen.
Unlike the boom box, it needs some adjustment to make these fire and water colleagues to help each other. The longest Bose came with wind, having potential to physically blow its British colleagues away, currently under the strict control of the pairs. It generates wind rather than sound. Some accident may physically damage QUAD, or even the window glasses, that is real. The pipe organ thing rated to handle 3,000 Watt power, now required to work with 51 years old twins that are designed for domestic use with a few fraction of a watt, or in micro-ampere order current.
Eventually, the sound lost its base that is rigidly connected to the ground took off into the wind. It may be just a giant blower and 51 year old plastic films, forced to work togather to make air move. That is up to an One Of the Most Stupid AudioPhile in this planet.
