In addition to the Wavelength, take a look at the Camelot Uther which has remote control, multiple inputs and an all-analog volume control. Used may be in your $ range.
DACs with volume controls
Okay, I love all this audiophile stuff, but I'm a private school teacher (little money). So are there any decent used or new DACs that I can purchase with a volume control and hence skip the need for the preamp? I'm thinking I can go 1.5 grand, maybe 2 if I wait till summer. Anyone out there use this stuff or heard it? I'm new to this sonic world and have only read about the Wavelength DAC, don't know any others.
