All the old tubes I tried were very coloured in my pre whilst I find the TAD's essentially neutral and better at frequency extremes. I'm using a quartet of these tubes now.
I have a quad of these and am willing to let go of a pair for half original price if your interested.
They have less than 50 hours on them and are matched.
