[SlimDevices: Audiophiles] Re: Suggestions for an up-to-date, available source for a linear PS
The ELPAC WM075-1950-760 is the correct model number for a 5 volt, 1.5 amp, linear, regulated, wall wart type of power supply with the correct connector that will plug direct into a Squeeze Box. Unfortunately ELPAC has discontinued production of this model in favor of a switching design. There may be a few around in the surplus houses or used on E-Bay. The ELPAC WM075-1950-D5 is the same linear power supply, but it comes with a 5 pin DIN connector on the end. It will need to be reterminated to be used with a Squeeze Box.

Thank you for the kind comments on the modded ELPAC. Supply IS getting scarce. Allied Electronics lists 10 in stock. Digi-Key lists 27 in stock. I believe ELPAC has discontinued this model in favor of a switching power supply. The D5 model has a 5 pin DIN connector on the end. This connector need to be cut off and a 2.5mm DC power connector soldered on. The D5 uses a four conductor cable from the PS to the connector.

My personal modded 760 Elpac has been up in Longmont on loan to Sean from AV123.com. I will get it back from him next week for RMAF. As far as a sound difference due to the cabling, I have heard a difference between a coax cable and a shielded twisted pair used for a SB power supply. There just might be a difference between 2 parrallel conductors (760) and a star quad cable (D5) used for DC.

I have not been able to compare the toslink and coax connection, yet. I have compared the stock switching PS to the linear PS on coax digital out.

In small quantities, a blank case can COST about $100.00. Then you need the machining for the display. The holes drilled for the outs and ins and then standoffs for the circuit board. I would not suggest keeping the power supply inside the same case as the D/A circuitry. The magnetic fields generated by the transformer would do some rather nasty things. So that would mean two cases. Then add in in high quality connectors, power supply parts, film and foil coupling caps, etc. You would be looking at a SB2 selling for over $1000.00.

That means noise on the supply lines to the DAC and audio section. Maybe I am just a hack with a soldering iron, but I do happen to care about how gear sounds.

Why not just connect it to a really decent DAC? By running direct from the modded Squeezebox 2 direct to a pair of good amps, you are getting rid of many mechanical connections, solder connections, and LOTS of parts. All of which affect the signal passing through them. In the system we described, there was one Sonicap between the DAC chip and the power amp. The power amps are DC coupled. To our ears, this was the best sound. I do tend to feel that keeping the signal path as simple and pure as possible will result in the best sound.
