I'm afraid I've been a bit lax in listening to this year's Proms from the RAH, owing to other distractions. I did however catch most of the performance of music by Ravel, Falla and Respighi.

Listened via my system: external Antiference omnidirectional aerial > Quad FM4 tuner (registering maximum signal strength on the bar-graph indicator) > Mark Levinson ML26 preamplifier > Quad 510 monoblock amplifiers > Quad ESL-57 speakers, I have to say the quality of the BBC transmission was as good as it always is.

However I did notice some background noise: not the hiss of electrical noise, it was more of a quiet 'whirring'. Given the high temperatures we have been suffering, it might have been some form of air conditioning.

Won't be able to hear any more on my system, as I will be away from home and only able to use an FM portable radio.
