Winter is coming.... 
Lol.

Looks like a fun new piece of kit. Looking it up, it seems there are several mod recommendations if you chose to get rowdy with a soldering iron.
In modding my Jolida, big improvements were in rca and speaker connectors from KLE and are a simple mod. Slightly more intrusive but equally nice improvement was signal path caps and hexfred diodes. Could make for a fun weekend of tinkering and sonic improvement.
Also you mentioned GL KT77 in there, but what are you running for front end tubes?
