Krell KAV 400xi

I have an opportunity to pick up one of these second hand. Is this a good little unit? I am using a sonos amp right now. Thanks...
Yes, it is a great unit. Puts out a lot of heat though, so keep that in mind.
You will like It they sound nice.
If you do get it, give it a good hour to warm up before you give it a serious listen. It sits in standby when you have it in your rig for very good reason.
I liked it a lot with Magnepan 1.6s, not so much with Martin Logan Ascent i.
Built like a tank, and yes as Elberoth says it gets hot, like you could fry an egg. Really.
