Couple of interesting bits of kit, wondering what the collective think.

DAC/Pre-amp

I've got an older version of this, but without the preamp. It has a
USB-in, and, from the manual:
--
In addition our own Windows driver (downloadable from
www.cambridge-audio.com/DacMagicPlus-Support) allows up to 24-bit/192kHz
operation and supports both kernel streaming and ASIO.

Mac PCs already support up to 24-bit/192kHz USB transfer natively.

I could use it with a Mac, or a media PC. This topic is almost entirely
lost on me - which might be best to 'serve' Apple lossless CD rips?

Wireless speakers

These seem to be very well reviewed - has Dynaudio cracked the
limitations of wireless speakers? Apart from the mains cables of course.
