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!

I saw you mention the single ended vs balanced difference before. Running into my Soulution 700, I do see transparency is better running directly. The Preamps I use are the best I have tested so far (MFA Magnetic Reference Silver edition). Of course I only run 2 meters of balanced cable from the DAC. Were the input impedance of the amps very low in your case? Regards & Thanks.
