Sam, also consider the
985 which is identical to the 2805 except that it costs less and comes only in silver. The differences in DACs(two per channel increases the signal to noise ratio by 3dB, but it's already higher than necessary) will make no audible difference in general since both the Texas Instruments(Burr-Brown)1791 which the 3805 uses and the Analog Devices 1835 codec(COder/DECoder, a combination ADC and DAC on one chip)are beyond the limits of human audibility and also beyond the needs of any audio format, with one exception. The exception would be if you were going to play one of the two channel DVD-As which sample at 192KHz(the multi-channel DVD-As sample at 96KHz)with a direct digital(Denon link)connection from the so far very-expensive Denon players. Then the 3805 with its provision for Denon link and its 192KHz converter would be necessary. Otherwise you'll never be converting digital 192KHz material to analog.
My view is that the 2805/985 is more cost effective, especially since it includes the necessary microphone which is about $60 extra for the 3805.
