First Watt (Pass Labs) F4 Spectacular Booster Buffer Amp [Expired]


no longer for sale

This might be the best of the First Watt amps--with the best characteristics of the F3 and the F5. The trick is that you MUST have either a high gain preamp or a flea powered power amp you want to use with regular speakers. I used it with a Conrad Johnson, and the results were sensational. Basically, this brings all the sonic characteristics of your super expensive preamp into play. It's the reverse of using a passive preamp. Here, the preamp is active and the power amp has no sonic signature. Only from the mind of Nelson Pass! Brilliant. Plus, you can even run a pair as monoblocks for huge power! This thing is big time genius. On either the First Watt site or the manual, Nelson Pass tells you which brands of preamp will work. Basically, any top brand of active preamp. This is like very expensive tubes without the fuss. No International or Canadian shipping.
