Re: "Audio" Valves
The amp' is a Croft Micro - probably about 20 years old and it was OK'd by Glenn Croft about a year ago.
I feel that I must emphasise, differences are subtle - far too subtle to be aware of unless doing consecutive listenings using the same source.
I was curious and sceptical until about 12-18 months ago, so decided to spend not too much ££ to find out and if you are curious and OCD enough to do back-to-back listening, you can hear differences. When my partner, completely oblivious to what has or has not been changed, describes what I hear, I am happy that it is not all imagination.
