Today they are sort-of back to normal but noticibly 'quieter' than the same program on FM. Getting better as the sun warms and dries out the roof (FM dipole in loft).
When the roof is fully dry, it is very good, even on DAB and DAB+. Better on DAB than the previous 2006 Onkyo version in fact, I'm quite impressed with it. I can switch between FM/FM Mono/DAB/ Optical 1/Optical 2/CD/Bluetooth (yuk) at the press of a button on the remote. Optical 1 takes the output from my PC sound, and when I can find an SPD/IF optical cable 2.5 metres long I'll connect my Samsung tv to it as well. (*)
A couple of reviews of this unit have mentioned very poor radio reception, which makes me suspect they are not in a very strong signal area and/or are using the supplied 'dipole'.
I'm definately going to make one of those dipoles in a length of kitchen waste pipe next year when it is warmer.
(*) I have read somewhere that once an optical digital cable exceeds 2 mtres in length, you need a good quality one.
