Hi Wig
No, I have been pretty satisfied with the stock tubes. Since I got the VAC about 6 months ago, I have been buying more vinyl to go with my TW Acustic source and have not felt the need to tinker further with my system for now.
I have to agree with your description of feeling like live performers are in the house with the VAC.
The VAC 160 is the heart of my system, with TW Acustic/Ortofon/Dynavector and Mac/ARC DAC8 sources, Audioquest cabling throughout and finished with Tannoy DC10T speakers.
