Hi Tomasz!
My experience was negative in going from 4TC to 8TC. I found the sound muddied in comparison - this was using NAD gear going to Triangle speakers. Returning 4TC to the system cleared it back up immediately, more transparent and open, better deep bass.
I am a dedicated fan of 4tc in my current system (Trends amp to Triangles), but these things are definitely system dependent. I had a Rotel integrated and little Tannoy monitors and found the 4TC added (or let through?) some irritating sizzle in the top end.
Good luck!
