Oh dear,

There I was thinking how nice it sounded through an EL84 amp and
home-made speaker in the 16kHz position. The audio must be better than
my ears - or is it that our local AM stations put out a high quality ?

Cecil,

That does make a difference. Still, the audio isn't that terrible on a

stock A, imho. It ain't great like the SP-660, but those are two 
different environments. I don't bandcruise a lot, so maybe I'm not 
missing a lot from the SW bcst stations. Speakers or headphones make a

bigger difference to me than the filters. Maybe it is just impressions,

but it seems to me that I get more audio 'data' from the tighter
filters 
like station ID, what they are saying, etc than I do with wider filters

and increased band noise and hets. Music is better on the SP, but is 
music that great on HF with any radio?
