10 watts out of the 845 is enuff for me> If you have some sort of very high output preamp
I have four preamps (two SS, an Aksa GK-1 hybrid, and a Magic 5).
The most flexible is Mapletree’s Magic 5, which has two switchable active stages, also two outputs.Output resistance:
SRPP: OUT1 - 5.4 kW, OUT2 – 14 KW
CF: OUT1 - 660 W, OUT2 – 14 KWTwo Outputs:
OUT1 - Voltage gain at 1 kHz (100 K load):
SRPP: 18 dB
CF: 23 dBOUT2 - Voltage gain at 1 kHz (100 K load):
SRPP: 8 dB
CF: 13 dBhttp://hollowstate.netfirms.com/magic5.htm
is the Magic 5 enough – what output are you thinking?
Cheers
