Someone please 'splain me

Budrew, and I suppose you already have streaming buffer size set to large? Wish I had other suggestions to offer...

Jayboard,
Thank you for the informative response. I'll read through it again tonight and proceed from there.
Regards,
Howard

Howard - Easiest thing from a networking and interface perspective is probably SB. Why not save the money on the USB/SPDIF DAC 'thingy' and buy a SB instead. Feed the CD/DAC via SPDIF - or try the SB straight to the preamp.

You are making this way harder then it needs to be

peace

Just to be clear, you only would need the USB/SPDIF converter you were
talking about getting if you were planning to connect your music server to
your audio system by a cable. You don't seem to be contemplating that.

I don't know much about the SB, but I'm not sure it's the best choice for the
last configuration you've talked about. The SB is designed to give you a user
interface for music playback, and like the AX, it also does the data conversion
to SPDIF and DAC (if desired) functions. If you're using iTunes on a computer
as the user interface, one of the main features of the SB is superfluous. The
AX is cheaper. A difference, if it matters, is that the connection for the SPDIF
signal from SB to DAC is coax, whereas for the AX it's Toslink.

P.S. I've come back in and added this as an edit. Actually, I do see a role for
the SB. Since you can't put your laptop in the music room, having a SB there
would let you use your music server while you're listening there. You haven't
said that's a factor at all, but it wouldn't cost much to make that service
available. Ckorody talked earlier about looking down the road at the big
picture. 'Course, if I were looking down the road, I'd be looking at getting a
wireless laptop to devote to your music room.

Thank you for the info. This is for background music only. I will not be spending time in the listening room, as we are launching a business that will have me out of the house for most of the day & evening. My wife will ONLY be listening as she works downstairs. She will have the music on upstairs only, NOT downstairs at her desk.

So, I just purchased a 320MB hard drive, with the specs you noted above, Ckorody. Also was able to pick up a Buslink USB 4-port PCMCIA card so I'll be able to keep the older laptop connected directly to the external hard drive, in the room with the audio system.

So, what I still need to know is will the SB and/or AX do the same thing that the USB/SPDIF converter would, thus making it superfluous. And if I'm not going to use the DAC from the SB, I can spend less and just get the AX, correcto?

Finally, do I need to be concerned about the caliber of cable running from the SB/AX to the DAC? Please keep in mind that we are of the camp that hears big differences between one IC and another. I'm not looking for tip-top audiophile quality, but I don't want it to sound thin either.

Thank you,
Howard
