很多网友换!
能详细讲下吗?

谢谢Peter 师兄, 是这样的: ARC Reference 近期推出了Reference 150SE 版本. 也就是将KT120  换成KT150!
也就变成了新的形号!
但是, ARC 不会帮你将现有ARC Reference 系列升级.
网上的看法是怕影响他们新的Reference 150SE的销售!
从网上看, 美国很多的用家, 已经将KT120 更换成了KT150, 反映是非常的正面的!
所以, 我想问有没有用家, 已经更换了KT150,
以下是参数的比较,:

ARC Reference 150se:

                                                                        POWER OUTPUT
150 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic distortion typically 0.6% at 150 watts, below 0.03% at 1 watt. Approximate actual power available at 'clipping' 160 watts (1kHz). (Note that actual power output is dependent upon both line voltage and 'condition' i. e. if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)

POWER BANDWIDTH
(-3dB points) 5Hz to 80kHz.

FREQUENCY RESPONSE
(-3dB points at 1 watt) 0.5Hz to 120 kHz.

INPUT SENSITIVITY
2.0V RMS BAL for rated output. (24 dB Bal gain into 8 ohms.)

INPUT IMPEDANCE
300K ohms Balanced.

OUTPUT POLARITY
Non-inverting. Balanced input pin 2+ (IEC-268).

OUTPUT TAPS
16 ohms, 8 ohms, 4 ohms.

OUTPUT REGULATION
Approximately 0.6dB 16 ohm load to open circuit (Damping factor approximately 14).

                                
                                                                        OVERALL NEGATIVE FEEDBACK
14dB.

SLEW RATE
13 volts/microsecond.

RISE TIME
2.0 microseconds.

HUM & NOISE
Less than 0.1mV RMS – 114dB below rated output (IHF weighted, input shorted).

POWER SUPPLY ENERGY STORAGE
Approximately 1040 joules.

POWER REQUIREMENTS
105-125VAC 60Hz (210-250VAC 50Hz) 730 watts at rated output, 900 watts maximum, 420 watts idle.

TUBES REQUIRED
2 – Matched quad KT150 – Power Output; 4 – 6H30 Driver.

DIMENSIONS
19"(48.3cm) W x 83⁄4" (22.2cm) H x 191⁄2" (49.5cm) D. Handlesextend 11⁄2" (3.8cm) forward.

WEIGHT
75lbs. (34.2kg) Net; 90lbs. (41kg) Shipping.

小弟初初用蛋机, 也是木耳!
请有更换过的指导下!
