One other thing about pairing electronics with Maggies. The sound better with a little bit of warmth.
I have a PS Audio BHK 250 that works well with my LRS+. This is a hybrid design that has tubes (one per channel) on the input stage, which gives it a slightly warm or organic sound, but still very clear and detailed.As its name implies, it produces 250 W a channel. This is enough in my reasonably large space. PSA also produces the same design in a monoblock version with 300 W a channel.
PSA is updating the top end of their line and has recently discontinued the BHK250. You can get a good used one for between $3000-$3500.
