I've been very impressed and somewhat surprised by the exceptional recording quality of the majority of the British folkies from the '60's and early '70's that I enjoy listening too. Try checking into recordings by Davy Graham, Wizz Jones (esp. 'Right Now'), Bert Jansch (and the group he performed in, Pentangle)and Mike Cooper, to name a few. Davy Graham is one of the most eclectic of the batch and a personal favorite...not to mention very nicely recorded.
