Outputing preamp to headphone

post #1 of 3
Thread Starter 

I auditioned this one tube preamp that sounds really good on a speaker system which is not designed for headphone use. I am wondering if I could feed the RCA output straight to a headphone using a RCA pair male to 1/4" female cable to my HE-6. Here are the specs of the mentioned tube amp:

 

Output lmpedance: 600Ω
Output Voltage: 2V(15V Max)
Input Voltage: 50-100mV
Input lmpedance: 470kΩ(RCA)
Distortion: 0.01%(20Hz-20KHz)
Frequency Response:10Hz-200KHz±1dB
S/N Ratio: 96dB
Vacuum Tubes: 5AR4x1,EL84x2,12AU7x1,6922x2
Voltage: 115V/230V

Thanks for all the help.

No one?

Does not look like a good match for driving the HE-6 directly.

 

HE-6 impedance: 50Ω

 

Ideally you would want an amp that has an output impedance lower than 50. The 600Ω rating from this preamp seems too high to me. But if you really like the way the preamp sounds, you can still use it together with a powerful neutral solid state headphone amp.
