First Watt J2. First Watt J2 Power Amplifier Photo 1887857 US Audio Mart By way of response, Nelson agreed to send me a pair of amps — starting with the J2, a 25wpc (into 8ohms) solid state amp that "has a two-stage circuit that operates in pure single-ended Class A mode, with signal JFET devices forming the input stage and power JFET devices for the output. With a device that behaves a little like a tube, it is natural to consider popular tube amplifier design topologies.

First Watt J2 Finally, we introduce the oldest design among the three amplifiers under review: the First Watt J2 stereo amplifier I reached out to Nelson Pass of First Watt this summer and asked the "what's what with First Watt"

The J2 is sublime, but I don't think this point can be made often enough: when a reviewer says an amp is "great," what he's really saying is that it's great with the speaker (or speakers) he's. Power output: 25Wpc into 8 ohms (14dBW), 13Wpc into 4 ohms (8dBW) Since its founding, in 1999, First Watt has developed over a dozen unusual, low-powered, but famously musical amplifiers, as well as five unique "line stage products" that include buffered passive volume controls and active crossovers

Hooked up to my Zu Essence speakers, the sound isn't merely spectacular; it regularly keeps me up long after I should have gone to bed FIRST WATT J2 Single-ended / two-stage Class A Signal JFET + Power JFET Topology Maximum output 30 watts @ 8 ohms / 15 watts @ 4 ohms Input Impedance 100 Kohms Balanced Input CMRR -60dB @ 1 kHz Input Sensitivity 280 mV = 1W , 1.4 V = rated power Gain 20 dB non-inverting phase Distortion 0.025% @ 1kHz Damping Factor 20 Frequency Response -1 dB @ 4 Hz, 100 KHz Output Noise 100 uV unweighted 20.

The J2 is a nice blend of parts that are not yet available and parts that are no longer available The J2 is sublime, but I don't think this point can be made often enough: when a reviewer says an amp is "great," what he's really saying is that it's great with the speaker (or speakers) he's.
