c2600 vs c52 for mc452


Need a recommendation for a pre amp for c452. 
What are the pros and cons of C52 vs c2600. 
How often would I have to change tubes on c2600? 
is tube failure a common occurrence ? 
Are there any audible imperfections with tubes vs ss? 
How big is the difference in sound between the two if using a ss amp? Is it noticeable ? 
I won't be able to test prior to purchase. 
This is mostly for classical music, with Vienna Acoustics Mozart Grands. 
Source is mcd550. 

my current system is ma6000 with mcd550 VA mozart and REL S5
