Buffalo II

The only drawback you have by using the PCI versionis that you loose the ability to manually mute it pressing a button. Maybe you can connect your motherboard spdif output to the spdif input on the EMU as a way to segmentate music from "the rest". The you enable/disable with Windows sound control panel's spdif slider.

Magsy, I believe that many of your problems are caused by your E-MU. Having 0404USB myself, I think its boring, very lean sounding and certainly not musical (both as a transport and soundcard). You should try a solution based on XMOS, I have Lorien's board - definitely a huge upgrade...

I would like to connect Buffalo II to some Naim Audio preamplfier.

Naim Audio is using DIN connections, it means that for any audio connection between Naim Audio components there is always one common ground (earth) cable for both channels.

From which place in Buffalo II (Legato) should i take the common ground for both channels ? I was thinking about connecting it to the ground at the power supply input in Legato pcb.

Any (good ) ideas about it ?

Are you using a 2 phono to din cable? I'd have thought, if so, that the 2 ground wires in the phono cables would simply solder to the single ground pin at the preamp end.

In this way one has two ground loops. I am looking for the best point to connect the single ground for audio signal.

Aren't you going to have 2 ground wires in the cable anyway though? Or is a two core cable with screen? You could I suppose join together the phono socket ground lugs and wire that back to the headphone ground on legato.

Or, use a din socket on your buffalo as well, connecting the single ground pin to the headphone ground on legato, and then din to din cable.

To make it clear - i am looking for the best SINGLE point on the Buffalo II with Legato for the common ground for two channels.

This is probably the 0V point between +-12V on the PS input, but i am really curious what the developpers (if any) can say about it

Hello Russ & Brian,

Thanks for putting the S/PDIF mux back into production. I ordered one last night. The manual specifies a 5-12vdc supply. Since I use a 12V battery to supply the DAC, ideally I would like simply to power the mux on the unregulated battery trunk. This supplies 13.8V for an instant at start-up, and settles quickly under load to 12.7V. Will this slight overvoltage work okay without damaging Mux?

Max input voltage for the LD1117 regulator is 15V. You will probably be okay.

Hi Russ/Brian,

I am using monoblock amps placed next to the speakers driven by Buffalo dac (with IV stage) via long interconnects. Different interconnects seem to impart different sonic signatures.

I wonder if I can place a current mirror after the dac to buffer the current output, and place the IV stage (Legato/Ivy) at the amplifier side to improve the interconnection (i.e. using current output instead of voltage output connection). What might be the pros/cons of doing this?
