Thanks Barry
It is really amazing how many people are still running with old Radfords. Of course much easier now that Will can bring old units into the 21c whilst still sticking with the ethos of Arthur's design ideas.
One idea Will and I have been tossing around is for me to get another STA25 and mono block them.
For now I'm about to jump on a new DAC and/or new preamp. May get a new Chevron DAC from Colin. An alternative I'm mulling over is a RME ADI-2 Pro. Not many reviews so far but looks awesome.
