幾年前找擴大機時，聽說日系中安橋推力夠
找資料發現了唯一這個網站有實驗室的測試數據
當時初階安橋609果然如網上所謂的推力相對足夠，但還是買了索尼2010便宜些但推力不會差太多，先鋒雅馬哈初階就不太行
後來今年打算上前後級，功放先找先鋒中階1522已用上D類後級，測試數據還可以
不過有機會還是上了安橋5008，想說消耗功率就上千瓦，總推力打七八折應該也近千瓦吧！
不過sound and vision 當初對5008的測試幾乎跟609差不多！？有人覺得是網站弄錯數據了
之後喇叭也換古力奇ultra II ，覺得有提升但再加上後級，才真正發揮ultra II 實力

5008的測試在兩聲道就正常許多 ,理論上多聲道不可能差到這樣
This graph shows that the TX-NR5008’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1 percent distortion at 162.8 watts and 1 percent distortion at 194.1 watts. Into 4 ohms, the amplifier reaches 0.1 percent distortion at 248.1 watts and 1 percent distortion at 309.5 watts.
看看歐美的多聲道後級的數據
Lexicon LX-7 Seven-Channel Amplifier HT Labs Measures
HT Labs Measures: Lexicon LX-7 Seven-Channel Amplifier
This graph shows that the LX-7's left amplifier channel, with two channels driving 8-ohm loads, reaches 0.1% distortion at 293.2 watts and 1% distortion at 322.5 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 245.3 watts and 1% distortion at 286.8 watts. An input level of 102.4 millivolts was required to produce an output of 2.83 volts into an 8-ohm load, indicating an overall gain of 28.83 decibels using the RCA input. When using the XLR input, a level of 205.0 mV was required to produce an output of 2.83 volts into an 8-ohm load, indicating an overall gain of 22.80 dB. With six channels driven into 8-ohm loads, the amp reaches 0.1% distortion at 199.5 watts and 1% distortion at 228.6 watts.
介紹一個國內近幾年很少聽到的品牌OUTLAW
看起來也是足瓦的後級,售價平易近人,官網就可以購買

Measurements
This graph shows that the 7500’s left channel, with two channels driving 8-ohm loads continuously at 1 kHz, reached 0.1% distortion at 284.9 watts and 1% distortion at 342.3 watts. Into 4 ohms, the amplifier reached 0.1% distortion at 447.6 watts and 1% distortion at 492.8 watts.
With five channels driven continuously into 8-ohm loads, the AVR reached 0.1% distortion at 260.1 watts and 1% distortion at 301.1 watts. The manufacturer’s stated distortion of 0.03% was reached at 238.7 watts, which is actually higher than the spec'd 200Wpc at that distortion level with all channels driven.

第一次在視聽室實際試聽Rythmik F15
第一幕就是迪士尼的片頭-迪士尼城堡放煙火
快要有去年在東京迪士尼樂園的感覺了,但是多一些小空間飽滿,心裡就決定試聽完就買fv15hp了
接下來看蝙蝠俠 黑暗騎士再起, 終於等到像樣的重低音所以第一次拿出來看
也體會到各個頻段的低音從頭到尾, 果然特定頻段崁燈會共振
後來看星艦迷航記一二集, 超??飛行這一震, 有快從椅子跌下來的感覺
看唐璜中夜店的場景,有當年去迪斯可舞廳的PUNCH感
至於吹動褲管,或許是空間小還沒體會到
