I reviewed the Lyrita Rubbra in my Summer_2017_2 survey http://www.musicweb-international.com/classrev/2017/Aug/Summer_2017_2.pdf

Of the recording quality I wrote 'Some allowances have to be made for the Lyrita recording quality, but not many. It’s mono, of course, and there’s one small glitch in the Cyril Scott, but otherwise it’s very acceptable'.
