Reliability of tubes/ Belles 150A vs Jolida 801A?

I'm nearly at the end of my upgrade quest. I'd pretty much decided to buy a Belles 150A Hotrod and Soloist preamp but my dealer is now suggesting I consider the Jolida 801A integrated instead to mate with Opera Consonance 120 linear cd player and Silverline 17.5 monitors.I've owned numerous tube guitar amps in the past and while I loved the sound, I haven't loved dragging them into the shop at regular intervals for maintainence. Are tubed audio amps pretty much trouble-free or do they share guitar amps high-maintanence needs? Thanks!
