Newer amps like the Yamaha MX-2000?

Hi, I have an old Yamaha MX-2000 amp that's been in storage for most of the last 15 years. A few months ago I pulled it out and listened to it again. It still sounds great with my maggies - to my ears, neutral and sweet, detailed, and a nice big soundstage. But I haven't kept up with the audio scene for a long time, and I'm wondering what new amps there are today that are like the MX-2000. I'm sure things must have come a long way. I don't really have any complaints with the MX-2000, just that I may be missing out on something. Given its age, I'm also concerned about my ability to repair it if it breaks. So my question is: what newer amps are comparable to, or better than, the MX-2000 with similar sound characteristics?
