Hi Guys,
I have been putting in many late hours the last few weeks on modding my Olive Symphony.
It is completey running on battery power and I am getting up to 8 hours of playback between charges
I have implemented mods to the analog output, analog input, digital output, headphone output, and power supply board. The power supply board has been heavily modded to accept 12Vdc power, and has been really beefed up!

I still want to play with vibration damping tweaks...
What is really special about this unit is that it IS an all-battery transport, but sooooo much more! Not only can you play CDs via the built-in CD drive (which is very smooth and quiet), but you can also rip directly to the built-in hard drive and then play back from the hard drive. No need to interface with a computer.... this IS the computer (built-in IBM PowerPC processor). Once music is ripped to the hard drive, it can also be burned onto CD-R. CD drive playback, ripping, HD playback, CD burning....it is all now done with very clean battery power feeding everything! Even the higher bit-rate internet radio stations are sounding good
As I've mentioned before, the board layout is as clean as I've ever seen in a music server, using all surface mount techology. This is also a fanless unit and runs very quietly, so it belongs in an audio rig.
I'll be posting lots of details of the mods soon. They have been very labor intensive and tedious (I do love the challenge though), but I must say now that the results have been most impressive and in a whole new class! I will definitely bring this unit to the VTV show!
Hi legalalien,
Nice to see you back here on audiocircle!
I really favor simplicity and this seems about as simple as it gets.
When it comes to computer-based audio, this is a very simple solution. Insert CD, press the RECORD button, and it rips the music to the hard drive. The names of the artist, album, songs, etc are all automatically filled in. The user interface is really slick....kind of like the iPod interface.
Vin you mentioned that the Musica had a pretty good volume control built in. Would it be better to not add a volume control on the CLARI-T/REALI-T and just use the one in the Musica or can you add a remote controlled volume to the amp?
Yes, the built-in volume control is implemented digitally (before the dac...which is made by Analog Device, Inc.) and is very clean sounding. If the Olive was to be your only source, it probably makes sense to go with a Clari-T power amp (w/o volume control) and use the built-in volume of the Olive. This is what rrgordon2006 is using (as he metions at the start of this thread). In the case of using a Clari-T integrated amp (more than one input), you'll need the volume control built into the Clari-T for the other sources if they don't have one.
is jitter an issue on the Musica as it plays music from a hard drive?
I have not measured the jitter, but John Atkinson did so in a Stereophile review of the Symphony and stated:
The Olive offered very good rejection of word-clock jitter, whether playing back hard-drive files or CDs...
For whatever that is worth, right?
And lastly, are you talking about putting all of this stuff(including the Monica DAC) into an existing Musica for the ultimate in simplicity!
I will be offering extensive mods to the Symphony and Musica, but am not planning on installing another dac inside. I really like the sound of the modded Olive's analog output and I believe that many will agree that it is really something special. For those who want to use their own external dac, I have tweaked the digital output as well (still tweaking and listening to this part).
I have a customer who would like to see a Clari-T built into his soon to be modded Musica. This can be done!
As it is now, the battery fits *inside* of the Olive and will be user replaceable. I had to install a bracket to hold the battery in place. Once I post pictures, you'll see how slick this has been implemented. You simply open the cover, disconnect the two wires from the battery, and pull out the battery to remove it. It fits like a glove and once the top cover is installed, the battery is nice and snug.
Initial testing shows that it can play up to 8 hours max between charges. Adding a built-in Clari-T board will probably reduce the max play time by an hour (still need to test). I would hope that 7 to 8 hours is enough play time for most people. In order to play longer, I'd need to use an even bigger SLA battery and externally mount it (in another enclosure), and this would take away from the beauty of the one-piece solution, eh?
Thanks for all your interest. More details are coming soon....
Best regards,
