As I recall from a recent review of the First Watt SIT-3, they work well with speakers that are 4 ohm and have 88dB sensitivity. In the review, the reviewer raved about how the Magnepan .7i pair sounded. However, they have a 86dB sensitivity. I have an SIT-3 (as a second amp) and Maggy 1.7i pair which also are 4 ohm and 86 dB. They sound great. Of course the volume knob on my preamp turns more to the right to move up the volume compared to my more powerful amps. So I am due to take delivery of my new second pair of speakers, the Magico A3. They are rated at 4 ohms and 88 dB. So I’ll see how they sound.
First Watt SIT-3 proper speaker matches
I have a SIT-3. I understand that it mates best with 4 ohm loads. I’m trying to find out if the amplifier is compatible with some 8 ohm loads. I am considering the Focal Kanta speakers that are 8 ohms and dip down to 4. The Focal Sopra 1 have been reviewed well with a 12w Valvet singled end solid state. I know there are other factors aside from impedance and efficiency but I’m not clear on the topic.
