I see what you mean, Stan.

And in a stage production of Porgy and Bess there was a real sense of space.
The station has moved on to Piano Music - that is very detailed and there is a good sense of space round it.
And Gimmel's 24/96 Studio Master Download Palestrina's Missa Papae Marcelli is amazing. Squeezecentre downsamples to 24/48 before streaming, - but the clarity is great.
One review I read complained of light bass - I am just impressed how much bass there is when the transducers are so far from the ears. I don't have the first idea what that "bass lens" does even though the handbook talks about it.
I am confused about the impedance of phones. Where can I read about that, Stan. These are low impedance phones (25 ohmns) you say. So they need less voltage swing but more current. Higher impedance phones - and some HiFi phones are 300 or more ohmns. They would need more volts and less amps (milli-amps, I hope!), but would be working with a much higher damping factor. On the downside won't the voice coils be heavier to their detriment?
I am very confused.
But these Sony F1s sound very good, and as you say break the design mould in many ways.

I note at this stage that I bought them off eBay with no fuss at all - that is some sort of recommendation, but no guarantee for others who might choose to buy from the same internet store.
