Simaudio I-7 or Pass INT-150

Both are generally well received amplifiers, but there are so many other choices to consider. Jeff Rowland, AMR, GamuT, Conrad Johnson etc. If you are interested i have listened and written about some of these products as i was looking to replace my own integrated.

Both sim and pass make great sounding stuff... you've already got the Supernova, might as well keep it sim.

I would agree, since you have the supernova and Simaudio uses Dynaudio's in their system at stereo shows, go for the 1-7!!

Sim and Dyn have a marketing agreement, hence why they are shown together. personally think the BAT is a better combination fwiw.

Keeping it all Sim does not guarantee the best sound reproduction. You'll only find that out if you widen the search net a little. To add to Keithr's comment, BAT makes a wonderful integrated amp which IMHO would be a better go-between for Dynaudio speakers.
