Best Match for NAD 7400?

I am debating between the rtia5 vs. the a7. I have a 15x20 room I will be listening to these in and I will not be using a subwoofer. My amplifier is 100 wpc continuous with 370 wpc dynamic output. I want to use all the amps power without overworking it. I tend to like to use my bass & treble settings to "hot rod" my music, i.e. I don't use the tone defeat button. Any thoughts are appreciated. I primarily listen to rock (buckethead, zappa, zeppelin) but like my bass at times. I'm leaning towards the a7's.

    WELCOME TO CLUB POLK!!

    Those NADs have tons of headroom so I'd even think about the Rti-A9s I like them better than the A7s, personally I think they are better for 2 channel music if you have the POWER. The A7s are fine for HT though. I agree with Kex...no sub....move up. The A5s have limited bass end....I'd say that my M70s can match and exceed their bass output quite easily, and they are a lower series!

    Thank you both for the welcome and the advice. I talked to P.A. tech support twice about this and they stated I may not be able to drive the a9 with this amp? I really want the 9's but I don't know if I can drive them. One of the people I talked to told me I was "pushing it" trying to drive the A7's with this amp. Personally, I think the 7400 would tear the a5's to shreds if I didn't run the soft clipping.

    I really am opposed to the subwoofer thing mostly on principle and would rather spend the money moving up from an a5 to an a7. I am currently running a pair of r300's that I bought off ebay for $75 with this amp. They were fine with my 304 (35 wpc) NAD but I found this 7400 and now want to see if I can get the cops over to my house.

    Throwing a monkey wrench in this whole equation, I have acccess to what appear to be a nice pair of SDA2 for $200 obo. Would I be better off with those?

    I forgot to mention, I'm even entertaining getting a matching NAD 2400 amp and running the receiver and amp bridged to run a set of speakers. I think that's about 200 watts into 8 ohms. That would sufficiently drive the A9's?
