wd,
At the end of January Steve talked about developing and offering a tubed power stage in a ZBox style case for use along with the Z-DAC. He didn't mention it, but perhaps he could add a variable output to that stage. . . .(?)

http://www.decware.com/cgi-bin/yabb22/YaBB.pl?num=1249180404/41"Bottom line is that I have actually been enjoying the upsampling dac by itself with similar satisfaction to what I was getting from the NOS dac with at least both additional stages activated.
So I continue to move forward. Chassis will be here in another 4 weeks with any luck and then I'll be able to take pictures and make the web page.
I've changed my mind on the BLOCK1, BLOCK2, BLOCK3 naming scheme. The dac performs so well on it's own, that I don't want to indicate a need for more with it's name. I called it the ZDAC-1. This way I can also leave the name of the ZBOX alone. I'll just do the gain stage and call it the .... something... I'll figure that out at the last minute like I always do.
The thing is, all three components will be the same size and visually match each other. The ZBOX and the Gain Stage will be optional. Using the gain stage will simply add a touch of tube joy to the sound and give you control over the dynamics. The ZBOX will have little effect on dynamics but will relax the presentation and make the system as a whole more forgiving of less than top notch recordings.
