HornEd,
I'm glad you were equally impressed as I was. I am just a Very Happy SVS customer. Tom (TV) is the infamous Sub-Human, Me just a mere mortal and true believe now! I bought two of their 20-39cs subs with the 600 watt amp offered at the time. The Samsom 700 should be even better and quieter than the Fidek amp. These subs will rattle your teeth!! If you want to read a ton of posts, from equally happy SVS'ers, make sure to visit www.hometheaterforum.com If you have hours of time to spend reading... Do a search on SVS in the Home Theater Hardware section.
I have a complete Klipsch Reference speaker package, RF-3,RC-3 and the RS-3 surrounds. These with the SVS package is a killer combo.
Klipsch is also coming out with a new line of Reference speakers and subwoofers shortly so that may be worth a listen also.
Good luck with what you end up purchasing and let us know of your results.
Curt
