What is the perfect tube amp for loud, warm, clean tones?

I use a Fender Jaguar and I play a lot of my music using a warm, clean tone. I will only use tube amps. I need an amp that has lots of headroom and will stay very clean and warm at HIGH volumes. I have previously played through a Fender Hotrod Deluxe and have been drooling over the VOX AC30 for sometime. My concern with the VOX is that it will start to overdrive too soon (although it's dirty is awesome lol). What other amps do these two companies provide that is great for clean and dirty?
