wilson sophia 3 + mark levinson 531H mono block + pre Mcintosh c50 + ps audio DAC

Despite the specifications, the Sophias are fairly easy to drive. The Levinsons are powerful and would be put to better use with Sashas. That being said, the Sophias will be very happy with them as well. Can't have too much clean power.

Agreed-

ML power amps will be a great match for the Wilson speakers.
The Sophia and Sasha are wonderful. I want to demo the Sabrina
as a comparison.

Most important of all, select cabling, will be paramount.

thanks for all suggestions .....how do you think about mcintosh pre c-50 to match with ML 531H
