Nope, what i meant is comparable with the DX100 which is 7 hours playback after fully charging.

 

I was thinking about the Alo Audio Rx MKIII...

I have been considering the SR-71B, but mostly for the ability to balance the left and right channels independently. I have a significant hearing loss in the left ear and option of restoring the left/right balance with a portable amp is an attractive possibility for me. Ray has told me that there were three or four purchasers of the SR-71B who had similar issues, and he had sent them amps without the volume knob, so they could adjust the channels independently. I wonder if anyone reading this forum needs to  adjust the right/left balance like I do, and how that is working out in day to day use. Is there a source for aftermarket stacked concentric volume knobs?

If you can get ray to send you an extra knob, i can precision slice it with my wire edm machine.

Or build you something like this.

Your choice of brass, aluminum, titanium, or even exotic woods.

I would need the exact dimensions to do this.

 

Free, other than the titanium which has high prices these days.

 

Gold or platinum too, if you are in a silly mood.

Señor Gilmore, that is a very generous offer and I believe I will take you up on it---I'm sending you a private message.

I have mine adjusted to make up for a slight loss in my left ear. Works very well but it does take a while to get it adjusted properly.

I have never had a problem adjusting the volume control for R and L with the set screws. It is quite easy.

My only fear with that is I'm so clumsy I'm afraid I Might strip it sometime. While I'm sure that if I screwed it up I Could send it back to Ray for repair, this time of year, sitting on the back deck, this gets a lot more use than my Apache. As far as adjusting, I'm always worried about creating an imbalance so it takes a lot of tweaking to get it just right.

Has anyone heard an update regarding Ray's portable DAC project to go with the SR71b?

post #986 of 1192
Last autumn it was supposed to be at least 3-6 months into the future, have not heard anything since then

I think he meant the 4-pin connector, which has been out of stock at Mouser for a couple months now.

It's by Kobiconn Part # 163-191J-E, surprisingly labelled as a "Camera Plug"  :-

The plug used for the 71b can be obtained form Ray.

The last I heard, keeping up wth orders for the Dark Star was taking a significant amount of time. As a result something had to give.
