Wadia 850 and Spectral DMA 150 matching without pre-amp

Can I directly connect a Wadia 850 to a Spectral DMA 150 without using a Spectral pre-amp?

I understand that the Spectral pre-amp give very current output (upto 1 amp) and a maixinum voltage of 100v peak for the power-amp. The guy at my local audio shop advised that Wadia/Spectral power amp direct connect would give poor dynamic range. However, I am not quite understand the reasons behind it.

Would anybody give me some advise.

Vtin, that's interesting. Maybe the Spectral, being wide-bandwidth, presents an uncontrollable load for the Wadia... but why?

The only difference b/ween yr Spectral & other amps is that the former easily goes up to 8Mhz vs. the latters' usual 20-30kHz. I would expect the choice of cables to be critical (I mean electrically) in this case...

Maybe Detlof (who's using Spectral), Sean or others can clarify?
