Running DCS Vivladi DIRECT?

Hey Folks,

Anybody out there who cares to comment on running the Vivaldi DAC direct  to the Power amp.

Please compare with running through your favorite preamp and elucidate the differences.

Thanks & keep enjoying our hobby!

The Ref 40 input impedance is 60k SE, 120k balanced. The Vivaldi spec recommends 10k-100k ohm

Isn't the Ref 40 the preamp?

What 's the input impedance of your amps?

I run my Rossini into my pre-amp, but I haven't plugged it directly into my amp as yet. I could check, but I am not sure what condition I would be looking for apart from a different sound, no change, or no sound. It's no Vivaldi (drool), but if sounds bl**dy great.

42k for the VTL MB450III, but not sure why that’s relevant as I’ve never tried driving them direct from the DCS ...

I have run my Vivaldi DAC directly into my ARC Ref 250SE’s and felt running the DAC into my Ref 10 preamp gives better sound - I agree with Folkfreak the line stage in the Vivaldi is not as good as it should be - especially for the money.
