I owned the Zodiac+ that I recently sold here, granted I'm not a big fan of the 'all-in-one' boxes (says the guy who just purchased a RWA AE) I have to say that the Zodiacs are outstanding DACs, from memory it came very close to my all time DAC reference the Weiss 202 (selling it was by far my biggest 'audiophile' mistake) and that means a lot (at least to me) but I thought the amp part was lacking a bit of power to make the LCD-2 truly shine, when paired with my now gone Audio-GD phoenix in balance mode I have to say it was an outstanding combo, in terms of neutrality and dynamic it might have been the best my LCD-2 sounded.
Another all-in-one option that I liked but didn't owned is the lynx Hilo, it doesn't get much love here because it's more geared towards the professional crowd but I spent ~1 hour with it and I was impressed (

One think is for sure with 3'000$ you have a lot of great option, if you can I would really try to find a place where you can listen to some gear so you get an idea for yourself, forums are great but nothing beat hearing things for yourself.
