I recommend the Squeezebox (classic model, otherwise called the Squeezebox 3) and a nice DAC--I use a Benchmark. Don't both with an "anti-jitter filter," but do find an upgraded or modded power supply (check out Bolder Mods for that). Much less expensive way to go than the Transporter, certainly than the modded Transporter. If you love the Squeezebox, you can buy a Transporter later. If you plan to use a DAC do NOT waste money on a Transporter. If you do not want to add the extra $$ and interconnects/power cords for a DAC, get a used Transporter right off the bat. But certainly don't go to the trouble and expense of buying the modded Transporter till you know if your home network is reliable enough to allow you to stream music wirelessly to your systems. I have 3 SB3's, all three used with DACs, in three different systems and am gradually parting with all my expensive CD players. Because I already owned the DACs, I bought SB3's instead of a Transporter (and at the time I bought the SB3 the Transporter wasn't even out yet so I didn't have the choice).
