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.!

I still haven't changed the fuse but may try that next.

My coupling caps are Audio Note Silver, I often wonder how V-Caps would sound, they are great in my cross overs.

My last re-tube consisted of NOS Telefunken diamond base E88CC (LV1, V2), NOS Sylvania 6U8A (V1, LV2), and Russian 6H23p-eb for the rest as recommended by Chris at the time.
