Best Naim Amp for Slim Transporter

Hi all,

I've been using a NAC112/NAP150 combo for about 6 years, but have a bad case of upgraditis coming on. My only source is now a Slim Devices Transporter which offers fantastic sound with all the convenience of a network player. All my CDs are ripped in FLAC format onto a 1Tb of RAID5 NAS.

My current preferred option is to drive a NAP250 direct without a preamp - the Transporter output stage has switched attenuators so I should be able to get the line level right.

The alternative option would be to downgrade the amp to a NAP200 and pair it up with a NAC202 although the preamp seems unnecessary to me unless you beleive the 'magic' some people belive the Naim preamps add to the equation.

Is anyone out there using the Transporter with Naim amps? What works best?

I'm currently driving a pair or Monitor Audio Silver RS6's, but may well upgrade these as well in a year or so, but I'm happy with the sound and other reviews of these speakers confirm they punch their weight against far more expensive competition.

Thanks in anticipation!
