Hey all,
I've been curious about this tech spec on amps/receivers - I seem to be finding a lot of conflicting info on DF numbers - some say it's a useless spec, others say the more the merrier...some say 20 is too low, 30 too low...etc, etc...
The only thing I've really been able to determine is that it's a measurement of an amp's ability to control the driver movement of a speaker, particularly the woofers/in the low end..
I'm running an Akai AA-R30 into Advent 5012s, and I believe the original DF rating of the receiver is about 40 (but who knows if it still holds spec) - bass response seems tight and clear to my ears...out of curiosity, I've seen DF ratings ranging from 30 to 50-ish on some other receivers from the same era (mid 70's - early 80's).
I guess what I'm wondering is - would I hear a pretty audible difference hooking up a reciever w/a DF of 25 or 30 up to the Advents (10" woofer) over my current receiver?
