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?

I have an older REL R 305 and its a nice sub.  I auditioned new speakers recently and paired it with an SVS and it was no slouch 
Calloway... 
I have an S5 as well, and chose it over the 212 SE.
1. Recently I've been wondering how much I am missing with the S5 vs the 212 SE.
2. I'm thinking one of the upgrades this year is dual subs, similar to yours. 

Thank you in advance for any response... 
Calloway how do you you have your RELs connected through Neutrik? Which REL is connected to what speakers and where do you have them placed? 
I just received the Antimode 8033ii yesterday and hopefully be able to set up today or tomorrow sometime. Do you leave the antimode on all the time?
