Emotive sira?

I just got a emotive sira

I am curious why it has 3 outputs

2 variable and one fixed

i know fixed should not be used in a stereo setup.

in my research I have found that this was built for member 2out2sea but haven’t been able to get in touch with him.

anybody know?

thank you, Scott
This is the best preamp I’ve owned and I’ve had several

theres more space around instruments and vocals in a harmony are more fleshed out and seperate

its quite amazing!
I had the Sira in my system for a short time but I did do some tube rolling for the input tube. Aside from a Tung Sol 5687, I tried Bendix 6900 and  RCA 7044 tubes. The 7044 is a nice sounding tube, but many were noisy.

In my Epifania I'm using a Brimar 5R4GY/CV717 rectifier and I really like it. I also have used RCA 5R4G, TJ meshplate 274, and the Phillips Holland 5R4GY tubes. I didn't try different rectifiers in the Sira.
So rolling input tubes would be the tube to effect tone not the others?
I'm going by memory, but I think the 7044 was warmer sounding compared to the 5687 and 6900. I may have even tried different cathode follower tubes and the 6080. I would have to check my tube stash to confirm. You can always just send me a PM and I will look.

Do you know what 5687 is in there now?
