I thought these might be fun to look at. The dac sounds very fine.ja in clear and hot, Tucson, AZ

larger can and a battery power supplyhttp://www.audiocircle.com/circles/viewtopic.php?t=18835&start=0
Enjoy,

the battery supply, taking up little room so that the whole thing is very portable along with my portable headphone amp. The voltage to the dac also needs to be increased to almost 6 volts from the stock 4.9 to really sing.I can plug in a wall wart, charge the batteries and listen to the unit at the same time or just use the wall wart.

How did you change the voltage to the DAC from 4.9 to 6V? Please tell me the parts swapout and locations.Also I would like to know more about the extra diode that you have implemented (is this what adjusted the voltage?). A picture often says a thousand words too.
Please e-mail me the details, if you would. I would love to try them out.
Enjoy,
Bob
I don't know how to post more than one image per post and no one answered my query as to how to do it.ja

the bottom diode is the added diode, which leaves two places empty.ja

I'm counting three SuperMacro's in the picture. Isn't that a bit excessive?I've got the silver SuperMacro v.3 w/ switches. Have you done some op-amp rolling yet?
The Monica II DAC seems to be getting some favorable comments, and I've been eyeing Red Wine Audio's Class T amp with built-in Monica II to power my AKG K1000's. One of these days..
one more diode the sound takes a jump to the better than most any 1000$ dac. A 25 cent part makes this dac jump.ja in clear, hot with a slight breeze, Tucson, AZ

John,I've followed Yeo's progress on his Monica DAC and looks like he has a winner. Are you saying that you have 7 diodes total? It looks like Yeo normally does 6. Does it matter what position you put it in instead of one of the jumpers?
I'm probably going to give his DAC a try. I want to get a smart charger and get the power issues squared away. If I don't make it easy enough for the wife to use, I'll never hear the end of it.
Regards,
to the string and ground to that diode or jumper to the end of it. Using 6 AA NiMH works great and I can even run it off of a cheap unregulated wall wart set at 12 volts and the regulation on the board cleans it very well.ja in clear, the sun coming up and another hot day, Tucson, AZ

I have to roll. AD797 doing the work right now. There are about a dozen to try out with 4 being very good, IMO.ja in hot, Tucson, AZ

I have one with the 634 buffers and no switches, one with 634 buffers and switches and one with switches and different buffers. I have the SR71 but the V3 really is much better in all areas.ja in rather warm, Tucson, AZ
Here is my review of the amp with photos.

The concept to see in a photo is fascinating. Could you post some details as to what Monica II is above and beyond an Altoid (cinnamon) box, toggle switches, and mic jacks.
Asynchronous reclocking. It does a fantastic job and in my current setup will run 18 hours off of 6 NiMH batteries. The input I used can be either optical or electrical cable for the digital signal. The leds are for on and one is for signal lock. You can read about it at diyparadise.com.ja in hot, hot and hot, Tucson, AZ

Here is an open veiw of the dac. This is a fun dac available at www.diyparadise. I use this as a portable dac powered by 6 AA batteries but it also sounds great at home.ja in clear and still hot, Tucson, AZ
