I subscribe to the advice that a higher end system will benefit from a separate pre but not necessarily a separate DAC and streamer. However, since I have not seriously looked at upgrading components for the last two years, I am not real familiar with the more recent all-in-one boxes. I know there has been a big focus on volume control which has been a weakness in the past. Especially if one is only streaming there is no question this option could provide the best value. You should certainly consider it and let your ears and wallet be your guide. I think the traditional "separates are always better" logic is simply not valid for everyone.
DAC's Streamer and Preamps
I have been searching for a DAC for a while now. In the meantime I have been using a laptop plugged into my preamp until I decide on the DAC I want. I definitely know this isn't optimal. In my search I have been looking at individual DAC's, DAC's with preamps or volume control, DAC's with streamers built in and sometimes all three. I wanted to throw it out there and find out what people's preference is? I know previously having everything separate was the best way to go but because of technology things has changed a bit. What are your thoughts?
