Where is Mach2music.com?

Apparently they have. I tried very hard to contact someone a month or so ago to purchase a unit. No response. Finally corresponded with an associate of theirs (PI Audio) who mentioned that the company had been sold and that the new owner was working on getting things going again, but so far nothing. I finally bought a mini and "tweaked" it myself.

Thank you for your answer.I was thinking of upgrading my mini to a battery psu. I have done all the software mods but i do need help implementing the hardware mods.
were you able to do the battery power supply upgrade?

I have not done that yet but the PI Audio group person that I corresponded with did mention that they can do that upgrade. You can find them at piaudiogroup.com.
