Emotive sira?

It is a wonderful preamp. Fred is a talented designer. I have an Emotive Audio Epifania preamp and Vita tube amps and love it. Music just comes alive.
If you want to make it even better email Fred about the copper V-Caps and the autoformer volume control. They are not cheap to do, but they brought my Epifania up to a whole new level.

FWIW, my Epifania is #2 and it's been in my system for 15 years now. I don't think I could ever part with it. 

Going from the stock caps to Sonicaps, the sound became less colored, but also a bit leaner and harder sounding. When Fred changed the Sonicaps to the V-Caps, he also did the autoformer volume control. Since I can't say what each would do individually, as a whole the sound became more organic, smoother, transparent, just really better. It's the equivalent to looking out of a window, then opening the window and removing that layer of glass.

Fred hasn't updated his site for long time, but he's still active. He just updated my Circa phono stage. Since he does lots of custom work he may even have other suggestions.

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.

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?
