Sonic Frontier Line 3 vs McIntosh C2500


Anyone has an opinion on this?
Should I switch my 15 yrs old Sonic Frontiers Line 3 Preamp for a newer McIntosh C2500?

Let us know how it sounds after break in (at least 100hrs).  
Which brand is the fuse?
Agreed on the break in... I'll let you know in about a month..
The fuse is Hi Fi Tuning Fuse Supreme
Not sure, but they're 4 massive things! He built like a 'rack' on the motherboard to hold them... I should've taken a picture b4 I closed it up.!
