Hello Dave L,
I've done just that, and still find the overall sound quality disappointing. Mind you, using wood case British-made speakers instead of those dreadful modern plastic and metal boxes that pass for speakers does improve things to some degree.
For me the 'problem' shows up most in music (not current 'pop' music which sounds absolutely awful whatever its recorded and played on
).
Tuned to BBC 7 (replays of the radio classics, The Navy Lark, Hancock's Half Hour, Round the Horne, etc.) it suits me fine.
So my current compromise is to use FM for music and Digital for speech - which means yet another remote control (eight of the blessed things, so far)!
Regards,
Alex
