Any transport suggestions for AR DAC1? Krell md2?

Dear all,

At the moment I have the following system: Audio Research SP11 pre, Classé 25 amp, Audio Research Dac1-20 dac, Accuphase DP60 cd-player (which I use as a transport) and B&W 802 mk3 speakers. Very happy with it.

I'm considering to buy a decent transport to replace the Accuphase. I have to buy it second hand so its difficult to try it at home before buying. Does anyone have suggestions? Is a Krell md2 a good choice? And a PS audio Lambda?

Thanks for the advice!
