     I just got my squeezebox up and running and I am enjoying it   I have listened to nothing but vinyl for the last 3 years and found myself listening less and less due to work and the time it took to set up the record player etc.
    I have a stock SB3 and I am running the analog out to my Mapletree Ultra 4 SE.  Is the sound as good as my Garrard 301 with SME 3009 and Klipsch MC cart, in a word no.  But the convenience is worth it, I am going to be listening to music much more! 
    I will be getting an external DAC and upgrading the power supply and hope to have it closer to vinyl sound.  I must say that this is the most impressive development in home audio in my lifetime.  I love my SB3

Great!  It really makes it easy to listen to exactly what you're in the mood for, doesn't it? 

You might want to investigate the Ack! dAck! 2.0 (perhaps with ultra-resolution option).  This is a battery-powered DAC, so it requires a bit more thought to your usage patterns.  You can listen for up to 8 hours at a time, but the battery will last longest if you listen for 4 hours and then recharge.  And you must remember to turn it off after each use.  But if you're coming from analog, you will really like the sound - in my humble opinion.    It comes with a digital cable.  www.ack-industries.com

I think you will. My modded power supply is on order with BolderCables. Even without it, I can tell the SB3 does not have the edge or digital harshness of my CD player (am using it as a transport). I can listen for longer hours and I listen to lot more music these days.
With a CD player, all these polishes/mats were driving me nuts (they do make a difference and I keep fussing with them for that reason). Goodbye to all those tweaks.
