Gallo Reference 3.1 with/without the subwoofer amp

Great q., as I am looking into that myself (I have a gallo 3.1 (5.1?!) system on order). The way I look at it is, if you are GOING to use a sub amp in order to have the speaker sound full range, then using the Gallo amp is the way to go, but as Grims states i would still use a SMS. My negatives about this arrangement are that bass frequencies are STILL tricky in most people's rooms, so where you put your monitors may not always be the best place for the sub freq., regardless of the SMS (which should improve things 2-fold. I also think that using a seperate sub will allow the main speaks to play all the other freq. with more ease. I guess another consideration is, if you will beusing the system for mostly music, like i am, u would want a pretty quick sub.
-Just my 2 cents.
Please let us know what you chose / do.

i just got a pair and was suprised by the amount of bass they had wihout the sub amp (this is with less then 20 hours on them).

I've only heard this mentioned in passing in forums,
but I'd like to see if anyone can confirm this:

I have an ARC Classic 60 on 3.1s in a small room,
(not the highest current amp of all time) and contrary
to a vast majority of forum threads have way, way too
much bass.... So much so that during bass heavy
parts of songs especially at high levels, the mids
will smear and get lost.

Highs and mids sound great in parts of same songs
w/o low end info.

The SA was actually suggested to me as a way to
DECREASE bass, adding SS dampening to the slow
woofer. I'm hoping this will help the midrange mud
I have from time to time. I've tried a few resistors
across the second terminals ala 10 Audio but results
were dubious at best.

I think more than an amp/speaker interface issue, you have room problems that need to be solved. Sounds like you and/or the speakers are in a room reinforcing mode, most likely 80-100 Hz. I would try moving youself and the speakers around a bit. And some well placed tube traps will soak up some of those standing waves.
