Manolis,
I would its a great way to go if you are looking for a neutral accurate representation of a recorded piece. There is also an undigitalness about the Lavry Dac, making for a really nice pacing/timing to the music. The Lavry adds an evenness throughout the listening spectrum, nothing is too forward or too recessed and had a great sense of detail.
I can only compare it to an older DAC that I had, the Theta Chroma 396. Fat bass, pushed forward highs, all over me like a bad suit, creating listening fatigue quickly. I kept buying new sets of speakers, saying hey whats going on here! With half a smile an a headache. Saying half hearted, wow this sounds uh, great.. not so good.
The Lavry definitely solved my front end fatigue sorrows. That's not to say that if your listening to a crap recording its going to change anything though, you will still hear a bad recording.
Overall I would say its strengths are its even presentation and the power of its pacing, its subtle but it really brings out listening grins.
As for the Squeezebox... I love it, I have access to all the gigs of music on my Mac (Apple Lossless) and its easy to use, also goes great with Sirius if you have a subscription, plus the oodles of other on-line music sources.
God Luck.
Mike
