Meridian Sooloos or Qsonix? which is better?

I haven't heard either server but both have gotten good reviews and there are some threads on Audiogon about them that you can search for. Both servers are most noteworthy for their display software, I think.

There is a dealer here on Audiogon, Sound Science, who sells servers called Music Vaults. They would be worth checking out also. I think he'd be happy to discuss his products in comparison with those you've already seen. He puts his phone # in his ads.

Thanks Tom. i'm going to look into that.

IMHO the Sooloos has the best interface. I have not found anything that comes close. If I had to rate them I would go Sooloos first and the Qsonix second. To me what makes the Sooloos is the ability to cross reference music. It really is going to come down to which GUI you like better. You can't go wrong with either. Believe me I wish I owned either of them!
