REL Vs SVS for 2 channel music listening

I have Zu Omen Defs connected to a NuForce STA200 (class a/b) amp. REL has suggested a T9/i https://rel.net/shop/subwoofers/serie-ti/t9i/

SVS has a cheaper SB-2000 which seems to be closer for half the price https://www.svsound.com/products/sb-2000

I've read numerous places that REL is way overpriced and SVS is great for music. I am aware of Zu's subs...would like to keep the price under a grand if possible. 


Opinions?
