Harman Kardon HK-990, NAD C-390DD vs Transporter DAC

[MediaCenter]

Need your feedback on DACs, what is the best route to take:

1) Transporter - Digital -> HK/NAD
2) Transporter - Analog -> HK/NAD

TIA

The NAD C-390DD is completely digital in it signal processing so anything but the digital input would be wrong in that case imho .
You get an DA-AD-DA path instead of just DA in the NAD , in fact thats seesm to be the whole point with nad's M" and 390DD

You are absolutely right about NAD but with HK its only one DA. I was recently using a preamp between TP and Amp. Removing the preamp makes it sound less fatiguing. I don't want to insert a preamp, but I have some additional sources and I want room correction.
