輸出功率 : 連續出力 1w+ 1w(rms & 8 ohm load)。
那是不夠推 AKG K1000 了吧?
看到說 K1000 建議要 15w RMS...

If you assume you want to drive 1 watt into the AKG K1000's, you need about 11V RMS delivered into 120 ohms. To get 100dB SPL, you need about 400mW, which is about 7V RMS.
An amplifier designed to drive 15 watts into an 8 ohm load can deliver 11V RMS. If the amp has a very low output impedance, it will deliver vuirtually the same voltage into 120 ohms; a very low damping factor tube amp will deliver more voltage, around 22V RMS if it had a source impedance of 8 ohms (since it is more lightly loaded).
So, any amp designed to drive 8 ohm speakers at 15 watts or more can drive K1000's to 1 watt. To get 100dB SPL, you would need an amp that can do 6 watts into 8 ohms (for 400mW into K1000's).
