Is there a SS amp that can offer tube bliss?

I currently own a tube system and love the sound. But honestly I'm not sure if I have the proper disposition for this tube thing. I cannot stand the constant worry over tube wear, looking around for NOS tubes, and wondering if maybe...just maybe my system will sound better if I spend still more money on different tubes. I would love to find a SS amp that will give me what my tube gear does and rid me of the worry about maintenance and the discontent inherent in tube upgrading. I've heard the Clayton M100s are wonderful and offer a "tube" sound. Any other SS amps to replace tubes? Any advice is most welcome.
Thank you.
