Need advise on pre amp/amp combo with JM Lab Mini


I am upgrading my system and have purchased the JM Lab Mini Utopia's. Does anyone have advise on a pre amp/amp or even an integrated that would bring out the best in these speakers? Thanks.

I use the YBA 1 preamp, and the YBA 2 HCDT AMP and it sound really good. I also heard it with a YBA integre DT at my local JMlab dealer and it sounded nice.
YBA has a Passion Integrated coming out soon for $4500.00.
Do you have a dealer near you? It should be a great match!
