the best, cost-no-object, music streamer?

What does "apple app compatibility" mean?

The Slim Devices aka Logitech Transporter is the absolute best streaming media product out there. I use mine with my FLAC audio collection and it works brilliantly.

There is a controller app available for iPhone and Android that lets your phone or tablet act as a remote control, browsing album covers and controlling the music.

Sorry guys, the guy is talking streaming which is not a sooloos, that is a music server, a streamer draws the data from another computer or nas drive,therefore if this gentleman is talking streamer that is
either a

Naim NDX $5,500.00

or a Naim NDS arround $20k

or possible one of the top Linn streamers

Bryston BDP1 or the new BDP2, no moving parts, no HDD...great sound.

There are a lot of ways to architect a network based system . The term "streaming" is no used consistently. The weiss MAN201 supports streaming (i.e. plays music files coming in over ethernet). The PS Audio Perfectwave bridge does as well.

However, any music server (such as the Bryston BPD 2) that can access data stored on a NAS is not technically streaming, but for practical purposes this makes little difference.

The options are many, and there are an increasing numbers of the high end guys offering very expensive and presumably good systems.
