There is a new king of Squeeze Box power supplies!
The Ultimate Power Supply MK IV

I have been working on ways to improve this power supply since I first built it.
I have changed the circuit a couple of times and tried out a few different cases.
I have now made a large improvement to the circuit. I have added a voltage tracking pre-regulator circuit to the power supply which greatly reduces the already low noise floor. This results in a more balanced sound, tighter bass, better soundstage and generally cleaner, clearer backgrounds.
A comparison was held at Scott F's place with members of GAS this week. ALL who were there though it a pretty major improvement.
I have updated the BOLDER Cable website. All who order an Ultimate PS from now on will get the MK IV circuit. By RMAF, I hope to have a circuit board made with this circuit. This will be used along with a new case design. The cost WILL be more than it is right now.
If you are interested, now is a VERY good time to get the latest circuit in the older case for a very good price.
People who have the MK II PS or the older Deluxe PS can get them upgraded to the MK IV. Most of the MK II PS can be upgraded to MK IV for about $150.00. Older models may cost a bit more depending on what you actually have inside the case. Please get in touch with me through E-mail.
