Emmeline, The Shadow
Last year I received a PM from a head-fier gbx2006 who sent this link http://www.aaroncake.net/circuits/volume.asp and asked me if I would consider digital volume control to make the P-51 even thinner. I told him I was already working on it but with a control with higher quality and usability for audio than in the link, and it was called The Shadow.
If you think the Emmeline P-51, Mustang, is very, very small, think again. The new volume control allows me to not only make The Shadow even smaller but also improve performance and usability.
Currently one disadvantage of the portable amps, specially when used with the very sensitive IEMs,is the quality & the balance of there volume controls. Without strict testing and selection analog volume controls are a big pain, they don’t track properly, and they don’t give the proper sound stage & the correct location of musicians & instruments. The most popular disappointment is when one channel tends to start before the other. Dust & contamination tends to cause cuts & drops of audio signal in one channel or the other.
Because of such careful selection I have more than 3000 miniature Alps volume controls that have been rejected sitting in a box. They don’t track properly. They are money down the drain. I pay dearly for 1200 pots every time I order them and they are not returnable.
Not only the money is wasted but also the time that takes me to sort the 600 good & acceptable pots out of the 1200 units. This make me silk knowing that there is no other alternative to get miniature pots from another company that takes pride in designing better ones.
For The Shadow I have been fiddling so far with three different DIGITAL VOLUME CONTROLS & listening to them for the last 7 months or more & found one that is much better than others. I have come to enjoy the one I have right now.
More info will be available with the picture of the production PC of The Shadow amp in few days.

A-10, "Thunderbolt II" Electrostatic Pre-amp/Headphone Amp Released
The product page has some photos of my new electrostatic amp. More details to follow.
Emmeline "The Black Bird" SR-71A
We are proud to announce the arrival of the newest edition to the RaySamuelsAudio line, the SR-71A!
We sold the last SR-71 about nine months ago. Unfortunately, parts became unavailable for that period of time. There was still a great demand for the SR-71 but we couldn’t do anything about it. During this time many ideas came to mind. One of them was to make the SR-71 a more flexible amp by adding a three-position gain switch, this way we would not need to modify the amp for those who want to use it for low-impedance IEMs, or for those who want to use the high-impedance full-size headphones like the Sennheiser HD-6XX family—this is what we did…

Emmeline, The Apache
The Apache, pre-amp/headphone amp, is a fully balanced dual mono product. It has two balanced and two non-balanced inputs. Balanced and non-balanced, active pre-amplification plus balanced and non-balanced headphone jacks.
The Apache utilizes four sections, balanced DACT, as an attenuator, customized to fit directly on a military specs printed circuit board. The components quality used on the pc brd are of the highest military specs, like “Dale Vishay” resistors with accuracy of .1% tolerance.
Specification (amp section)
- Input impedance 50K
- Output impedance 2-2K
Emmeline II, "B-52" Released
Ray Samuels Audio is proud to announce its latest state of the art component:
The Emmeline II, “B-52” fully balanced Headphone amplifier and full functioning preamplifier.
It has been a long time since we have displayed the prototype B-52 in its silver non-anodized chassis at the 1st annual Head-Fi National meet. Since then we have re-worked the entire chassis over again to give it a better, more professional and functional look. In the process, both of the internal PC boards were redesigned in order to accomplish a higher quality of workmanship and to implement a newer custom built toroidal transformer which was designed exclusively to our specs, for the necessary voltage, current output and physical size, that we needed to attain our goals by one of the most respected manufacturers of power transformers in the world, Plitron.
