amplifier's "slam-factor"

An output impedance of 2 into an 8 ohm load gives a DF of 4, not 2 as incorrectly stated. (This is ignoring the change caused by the cable) Although if you look at tube amp specs you'll often see ones claiming DF's of <2. I believe the Cary 300SEI (from mid '90's) actually went up to a 3.8 ohm output impedance.

Sean, I use the Rockport Syzygy speakers in a 16 x 23 x 8'6" room and can hear the transition to Class B on musical peaks when running just 10w of Class A and can't hear the transition with about 30w of Class A via a switch on the JC-1s....

Stehno: As to the Primare piece, i would have liked to have grabbed it, especially at that price, but i'm not upset about it. Then again, i don't know what i missed either : )

As to listing my systems, i had done that at one time on AA and had one of them listed here. Quite honestly, i pulled them down for security reasons. I and several others discussed this privately and came to the same conclusion i.e. we didn't need to advertise what we had. Quite honestly, i do not live in what is the best part of town, hence my desire to relocate. Two houses on our block have been burglarized in the last year, so no sense in pushing the matter if you know what i mean.

Bob: Thanks for the response. The point i was trying to make was that others may have different ideas of what they think is "loud" and have lower efficiency speakers AND have bigger rooms. While that is a tough situation ( big room, low efficiency speakers, high spl requirement ) for sure, i'm sure that it does exist. Just as i would have laughed if someone would have told me that i needed 1200 wpc to power a set of speakers before owning a set of them, i no longer rule things like that out anymore. Each situation is different and we all have different goals / priorities as to what is most important to us within our own systems. Sean
