Linn AV5140 & 5120 advice

Hi,

Looking for speaker advice for a dedicated HT room. The room is 12’11”x 9’5” with 7’11” ceiling which is pretty small, basically a bedroom that I’ve remodeled. Running the speakers on the short wall with a love seat about 40” from the rear wall. Listening position is 80” from the LCR speakers. Currently NHT M5 speakers used for LCR duties, SVS CS-Ultra sub. No surrounds yet but want to end up with a 5.1 system. Using Integra Research RDC-7 pre/pro and RDC-7 amp for electronics. I’ll be acoustically treating the room with Real Traps to help smooth out room frequency response.

Would like to upgrade the LCR and have an opportunity to get a Linn AV5140 mains and AV5120 center channel for a pretty good price. Is this to much speaker for this size room? Are these good speakers for HT movies, concert DVD’s and regular TV? I have a dedicated 2-channel room for my vinyl listening because I didn’t want to mix the two.

I’ve also considered PSB Platinum speakers, Revel Performa line and Totem speakers but all are allot more money than what I can get the Linn speakers for.

Also, what surrounds would work well with the Linn’s if I did get them? Or generally good all-around surround speakers?

Any comments from past owners would be greatly appreciated!

Thanks!
Brian
