I just got my Jameco 5V LPS in about 30 minutes ago, and am using it to power the OpticalModule instead of the Uptone Audio LPS-1 (as mentioned above, when I was using the LPS-1 to power the OM, I was using a Jameco 9V LPS to power the microRendu; still trying to decide which sounds better...) I've been reading a very lengthy, very technical thread at CA originally started by John Swenson (the designer for the Uptone Audio LPS-1 as well as all of the Sonore streamers) on the impact of low-impedance and high-impedance leakage currents from, in particular, switch-mode power supplies (aka SMPS) in digital streaming playback....it is been quite enlightening and lays quite a solid foundation as to why we hear such notable differences between USB cables, Ethernet cables, and Ethernet switches. Its very much a technical discussion about low-impedance and high-impedance leakage currents and their deleterious effects. Anyhoo, I digress; back to the OpticalModule....

The opticalModule and LPS arrived this morning. I am all connected and so far everything sounds very good. There is a difference but it will take some time to figure out what I am hearing (or not hearing). It does sound quieter.
Initially I inserted the device right after the switch with the long run of ethernet to the Upsampler. I have ordered a long optical cable that should arrive this weekend. At some point I will replace the long run of ethernet with the longer optical cable and place that between the switch and the opticalModule which will be very close to the Upsampler. |

Play around with various configs and see what sounds best. I'm interested in what you find out. Are you using your Keces to power the OM? It runs VERY warm (hot, actually) at 9V; it runs considerably cooler at 5V.

When I had the GigaFoil I also had the Keces P3 for a couple of days. The dropouts were driving me nuts so it never received a fair review. My initial thoughts were that the Keces muddied up the sound and I was tempted to go back to the power supply that came with the GigaFOIL . I returned the GigaFoil, Keces and AQ Diamond cable. |

I received the long optical run this afternoon so I was able to replace the long Ethernet cable and move the opticalModule close to the dCS Upsampler. I will probably pick up a better short cable for that last .75 meter between the module and upsampler.
What really surprised me was how hot both the opticalModule and its power supply were as I disconnected them for the move from upper to lower levels. That is by far the hottest any piece of my gear has been. |

What voltage was the OM being powered by? I found the OM got REALLY hot at 9V; it runs MUCH cooler at 5V.

The display says about 4.8.

Hmmm....mine is running pretty cool at 5V; cooler than my microRendu.
Mine is sitting up on two little rubber blocks to allow it to get some air underneath it.
