最近有人推薦我RudiStor的耳擴(他是“強力”推薦)
this one: http://www.rudistor.com/NX03-steel.htm
RudiStor NX03-steel (小弟沒錢就只能買入門的)
所以我在網路爬了一下文
但是突然注意到好像沒有很多人有這個耳擴= =
不只這個....RudiStor 其他的耳廓也是擁有的人少之又少
(不然就是頂級到爆炸的型號010, 030 RP2000-V8(這台要50萬)...= =)
我的耳機是sennheiser HD650
但是大概比較了一下同等價位的耳擴,發現他的Specification是同等級裡的佼佼者!!
Maximum Output: 1.5 W on 16 Ohms Output Impedance: 0 to 1000 Ohm
Maximum Swing: at 32 Ohm 16Vpp Inputs: 1 x Analog, RCA- Gain: 15 db
Bandwidth: DC-100.000 Hz < 0.15db Noise Floor below -113db
THD: 0.003 % (13Vpp on 32Ohm) Amplification Class: Always A-Class
Weight (Kg): 3.2kg Dimensions (cm): 25x25x5
Output Impedance 也夠力 (到1000Ohm)
S/N 也有 below -113db(應該是這個吧?noise flow)
還是A-class的XD
想知道各位大大的意見 :3
畢竟買幾乎沒人推的東西是很可怕的........
謝謝^^
所以希望買一個比較好一點的耳擴先XD
(事實上也有在考慮SPL^^)
但它的specification好像並不是那麼好= =(以它的價位來說)
Frequency Response: ‹10Hz to ›200kHz (-3dB)
CMR:-80dBu (@1kHz, 0dBu input level and unity gain)
Crosstalk: -67dB (@1kHz)
THD: 0,005% (@ 1kHz, 0dBu input level and unity gain)
Noise: -97dBu (A-weighted)
Dynamic Range: 129,5dB (@ 600 Ohms Impedance)
要6W noise 還只有-97db....(PS: "Noise" 是指S/N Ratio嗎?.....)
output Impedance好像也只有600Ohms??
RudiStor我只是怕它推不好^^(有人說他推較高阻抗耳機會比較不理想 = =)
(PS:對啊!看價位就覺得是貴族廠牌XDD而且好像論價位也幾乎無人能稱呼其右??的樣子)
不過是用來推T1, 還不是SPL Phonitor 2太貴且沒被動喇叭需求 XD
Phonitor mini 規格如下, 看起來比自家Auditor好且又有rca輸入
Inputs
XLR connectors, electronically balanced
Impedance: bal. ca. 20kΩ, unbal. ca. 10kΩ
Max. Input Level: +32,5dBu
RCA connectors, unbalanced
Impedance: ca. 10 kΩ
Max. Input Level: +20 dBu
Considering that the RCA input is raised from -10dBV to +4dBu (approx. 12.7dB), the input level is comparable to that of the XLR inputs: +20dB + 12.7dB = 32.7dB
Headphone Output
6,3-mm TRS connector
Pin wiring: Tip = Left, Ring = Right, Sleeve = GND
Impedance: 0,18 Ω
Attenuation Factor: 180 @ 40Ohm
Frequency Range: ‹10Hz bis ›300kHz ( -3dB)
CMR: -106dBu (at 1kHz, 0dBu input level and unity gain)
Crosstalk at 1kHz: -88dB
THD&N: 0,00052% (at 24dBu input level and unity gain, 1kHz, 100 kOhm load)
Noise: Unweighted -100 dB; A-weighted - 103 dB, CCIR -94 dB
Dynamic Range: 133,62dB
Max. Output Power:
2x 1W (+30dBu) at 1kHz and 600Ω connected impedance
2x 2W (+30dBu) at 1kHz and 300Ω connected impedance
Power Supply
Voltages: 230 V AC, 50 Hz / 115 V AC, 60 Hz
Power Consumption: max. 15 W
Fuses: 100-120 V AC: T 500 mA /220-240 V AC: T 315 mA
Measurement & Weight
Height x Width x Depth: 44 x 144 x 257 mm (1,72" x 5,76" x 10,12")
Weight: 2,03kg (4,48lbs)
0dBu = 0,775V. Specifications subject to change without notice.
