I have owned a good num of First Watt amplifiers I have had great synergy running high output tube preamps with them.
First Watt F8, passive preamp, DAC
The F8 is comparable to other First Watt amps in terms of wattage but the gain is only 15db. The Stereophile review says to be wary of using it with a DAC volume control and presumably a passive pre. Can anyone speak from experience? My speakers are Devore, 91db, 8 ohms, and I would like to control the F8 with my DAC.
