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.

@zm thanks for your input. I read good things about the LTA MZ2 and MZ3 pairings with the SIT-3. Like you i do like clarity, transparency, speed, timbral accuracy of the SIT-3. Tad bit of tube bloom is fine but too much not so (which i assume is what you were experiencing with the Don S). Hence i was leaning the way of the MZ3, but wasn't sure given its ~10db gain and my speakers are 89db sensitive. I don't listen loud but my current preamp's gain is 24db and my knob is usually (depending on the recording) between 930am and 1130am. What speakers are you using with this setup?
I'll put another vote in for the Supratek.  Everything Tvad said is relevant and there are literally no bad reviews.  
I have the mz2, a great preamp overall but not capable of driving the sit3 to its full splendor.  Dynamic range & bass mgmt arr simply not as good as higher gain pre-amps.  In my stable the VRossi L2i does a great job, the preamp section of a Lumin or Mola Mola dac is amazing as well (the latter set @6V)
Hi @vinpic,

Thanks for your input on the the MZ2 preamp. What speakers were you using when you had the MZ2+SIT3 in your system?
