What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

First Watt
SIT-4
5000
/
Released
2023
The SIT-4 is the most recent amplifier produced by First Watt, and is the fourth to use Static Induction Transistors (SIT) as the power amplifying device. In 2011 we introduced our first SIT amplifier using a custom Silicon Carbide (SiC) transistor part made by SemiSouth. The amplifier used a single power device, operating without feedback in single-ended Class A "Common-Source" mode to deliver 10 watts of power emulating the characteristic of a Triode, but operating at voltage and currents directly needed by loudspeakers, eliminating the output transformer.
Check Amazon
First Watt is a project by Nelson Pass that focuses on minimalist, low-powered Class A amplifiers using unique Static Induction Transistors (SIT) to create a tube-like sound in solid-state format. The brand is known for its experimental approach, releasing limited production runs that explore different circuit designs with very few parts, which appeals to audiophiles seeking both technical simplicity and an emotional connection to their music.
Expand Details

Our Summary

Product Strengths

  • Uses a Static Induction Transistor (SIT), which has characteristics similar to a triode vacuum tube
  • It expands and opens up soundstage, with a gorgeous sound and great midrange, with voices sounding present and full-bodied
  • The amp holds a conversation with the speaker, letting it 'have it your way'—rather than forcing its own sound
  • It's spectacular on tone complexity, spatial hydration, fleshiness and vividness, making it sound off-charts organic, elastic and tangible
  • The main aspect that positions it noticeably above all other amps is immersion, making music three-dimensional, material, enveloping

Product Considerations

  • The SIT-4 is a limited production piece due to the limited availability of the Tokin SIT transistors
  • The power output is limited (10 watts into 8 ohms, 5 watts into 4 ohms), so it's not a universal amplifier
  • It is not ideal for speakers that require a lot of power, like Magnepans or electrostatic speakers
  • The power switch is located on the rear of the unit
  • Runs very hot

Comparisons (according to reviewers)

  • Vs First Watt SIT3: It sounds cooler in tonal balance and has more 3D imaging and body
  • Vs Pass Labs XA-25: It sounds more immersive, while the XA-25 is sharper and more focused
  • Vs First Watt F7: SIT-4 felt more gathered, punchier and texturally juicier, the F7 was more diffused, innocent, icier, leaner and color-wise opaque
  • Vs Elekit TU-8900: It is more rugged and expressive, while the TU-8900 presents recordings more aesthetically

Takeaway: The SIT-4 is a specialized amplifier that produces great sound with the right speakers, with beautiful tone and expands the soundstage. It's a good option for people who like tube amps but want a solid-state amplifier.
