Emotive sira?

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?

Oh and the rectifier?

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?
