Lol, 8 ft Cardas would be a tad pricy!
I’ve got the tube preamp , too
I has it with Thiels
I also retubed a with a cyro tube that really gave me the “ English gentleman “ sound that I was looking for
No subwoofer ?
Or do you have the full range you want ?
Thiels were in need of a bit of taming, but the effort was worth it
I also noticed electrical cables helped harshness , especially rohdium content
Keep up the good work
