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
I had a C47 and when I finally switched to a Audio Research Reference 6 tube preamp I realized how much more my MC452 has to give. My suggestion is either the C2600 or a different brand solid state preamp. I’ve been underwhelmed by the midrange Mac preamps. I’m betting the C1100 is pretty good. Still, for the money, there are a lot of great preamps out there.
