First Watt SIT-3 preamp pairing advice


Hi There,

I have Nelson Pass's First Watt SIT-3 power amplifier. I am using a ~15 year old VAC (Valve Amplification Company) Standard Preamplifier with NOS Telefunken 12AU7 and 12AX7 tubes for the 2 stages. I am looking to upgrade the preamp and am considering the Passlab XP-12 or the Linear Tube Audio MicroZotl MZ3 preamp. My impression is that both preamps are fairly popular when pairing with First Watt amps. Anyone here have paired both these preamps with the SIT-3 and can provide impressions that might help me decide? If there is 3rd option that you like very much, I am all ears too. Thanks in advance for any advice.

Thanks @tvad ! I will look into the Supratek and looks like folks when considering the Supratek are also considering the Don Sachs preamp. So many choices! Have you paired the Supratek with the Sit-3?

The Supratek is a great match for the SIT-3. I had the Cabernet DHT/6SN7 model, which has high gain. The gain is also adjustable, which is great for really dialing in the sound and getting rid of idle hiss on high sensitivity speakers. 

What are your speakers?
