that cradle is brilliant! very stylish piece of work from Pana.

does it actually come with speakers or is that just for show?

Wow awesome!! With buttons on the cradle the unit becomes sort of a minisystem for stationary listening!! Actually that's totally cool!!

Jilomen,
That's one of the kenwood model. Will 3.5x2 mw be sufficient? Very elegant system non the less.

only 3,5 mW? that would be sufficient for earbuds only. better not be rated at 16ohms!

Ohms does equal resistance, so 5 mw X 2 at 16 ohms is equal to 2.5 mw X 2 at 32 ohms.

I think.......

Which would mean that 3.5 mw X 2 at 22 ohms is...............not much compared to 10 mw X 32 (or 20 mw X 2 at 16 ohms.....!!!).

I though that lower was better, since ohms=resistance??


yes, ohms is resistance. with headphones and speakers it's variable, changes with the frequency, so it's called impedance then. lower is 'better', easier to get loud. too low and the amp sortof looses grip, the speaker will react too roughly, which is not good either.

the resistance referred to in the power rating of an amp (here the MD's internal amp) is the resistance the output is measured against. a higher 'load' is harder to push as you might imagine, so in power ratings it's best to calculate it to a standard so you can compare. as Vij said, 10mW at 32 ohms is close to 20mW at 32ohms. it's a bit more complicated than that I believe, but it's close enough.

so, while 5mW at 32ohms would be quite ok, if that 5mW is rated against only 16ohms, then that''s not os hot.
