I just wanted to get an idea of the kind of tubed amplification used to drive WP7s -- both SET and push-pull. I know the Lamm ML2.1s are on the top of the list. What are the other WP7 owners using? Thanks.
While the 7s are efficient at 90dbs, the impedance isn't the easiest of loads from what I recall in Stereophile. It falls to 2-3ohms in part. Would be tough to recommend a SET here.
I think the ML1.1s would work better with 90+ watts.
If I am not mistaken I believe that the WP 7's have an impedance of 93 Db. I do agree however that Vladimir's M 1.2 Reference would probably work better here
