Fred Volz and Emotive Sira Pre Amp


After many years enjoying my aging Audible Illusions Modulus preamp, I finally began searching for a replacement. About a year ago I ran across Emotive and their Sira line of tubed preamps. I had considered an AES, Cary, newer Audible Illusions, Prima Luna, and even Supratek. But, I kept going back to the Sira, I just had a difficult time justifying the cost vs. all of the others.

From the pictures it is a beautiful piece of audio gear. However, finding reviews on it are a little difficult. I would see occasional used ones on the market, but never quite pulled the trigger. I decided to contact Fred at Emotive to determine what upgrades could be done to a used one. After much correspondence, I decided to have Fred build one for me rather than buying used.

I am a bit of a guinea pig on this build as Fred is making some slight changes from the existing Sira. I do not pretend to understand audio circuitry so I can only say that the biggest difference is the chassis will be aluminum rather than the existing stainless steel. Perhaps Fred will see this thread and chime in.

I am hoping this new model Sira will sound as good as the limited reviews I have read of the existing Sira. The build is in process so delivery is still TBD.

I will use this thread to chronicle the process and the result. I realize that it's a little unfair comparing a new boutique built preamp to a 25y/o circuit board based tube preamp, but it will have to do.

I would like to have found more reviews on the Sira, but there is little out there to read. My experience so far is that Fred is an easy gentleman to work with and the gear that he makes is beautiful in my opinion. I will be honest in my assessment of it's audio and aesthetic qualities, so stay tuned to this thread for updates. My hope through this thread is to provide more information for anyone considering one of Fred's creations.

Fwiw my current set-up includes;
Cary cd308 cdp
laptop based music server w/ onkyo interface
Parasound dac1000
Audible Illusions Modulus 2D
AES Six Pacs
Gallo Sub Amp
Gallo Ref 3.5
all gear isolated w/ black diamond cones on 2" maple shelves w/ cork and rubber isopods.
Gracenote Speaker Wire and power cables
Homegrown Audio Super Silver I/c
Mapleshade digital connects

Things are moving ahead slowly, but surely. I am still hoping to hear comparisons between various preamps and the sira. Does anyone have anything they can add.
I would like to help you but my listening time to the Sira was almost 7 years ago so recollections are rather vague. I compared it to two other Emotive models---the Erato (which I owned) and the Poeta---as well as an Audio Research LS-2. I liked both the Sira and Erato very much but eventually decided to go with a custom version of the Epifania with a solid-state regulator. One aspect of the Sira that I recall vividly was the see-through transparency on live recordings. It also had very wide dynamic swings on orchestral recordings.

If you google the Sira, you can find a number of reviews and user comments from back when it was first introduced.

The sound of the Sira will be affected quite a bit by the output coupling capacitors. You mentioned that Fred was using his basic cap, but do you recall what cap that is?
I am not sure of the components being used throughout the pre including the caps. I am leaving room for improvements later. For now I can only imagine the caps being the most basic ones that Fred feels will sound good. I can't imagine them being crap, but I honestly don't know.
I looked back through my correspondence with Fred and found where he is using carbon film resistors that he has not tried in the past, and I have asked regarding the caps.
Ok, so a small update. Fred says the wood is in and he is finalizing the build. Mine is in a queue so it will be a little longer.

The circuitry is supposed to be the same as the standard sira. The chassis is aluminum rather than stainless and Fred indicates that he has tried engraving on the aluminum rather than silk screening. Mine will have Teflon tube sockets and a new switch that Fred is trying. The output caps are stock polypropylene in oil made to Fred's specs. Upgrades for the future are the volume pot and caps. But, I want to try the amp as specd by Fred. We will see then if I even feel the need to upgrade.
