Bought a new McIntosh amp

I think most people agree that if you have doubts and as you are on a budget, then take it back as it could end up being an expensive mistake. I tend to agree you would get more benefits out of a speaker change. However if you go for the Klipsch I do not understand why people are suggesting so much power for a speaker that is 99db. A 16watt tube amp at a theoretical full volume would give you 111db. A friend of mine is driving 96db speakers with an 8watt 300b amp in a room that is 22ft by 13ft and that goes as loud as most sane people would want, and like playing my music loud!

If you like the Klipsch, your end game should be Class A SS or tubes.  A tube preamp with solid state is a nice combination.  Mac gear looks nice, is reliable, sells well but I am not a big fan of their sound.

Hello,
Go back to the store and listen to your different amp options on the speakers you have or want. You should be able to hear the different options before making the purchase. This isn’t a Ferrari that you have to buy before you can see what it can do. I don’t know why you would need more power for Klipsch speakers. Maybe these amps have different sound signatures. That’s their job to show you, not the other way around. 

Your Rotel combo and that Rotel amp looks very desirable to me. 

I would return the McIntosh, and try different speakers as others and you discuss. My McIntosh C28 and MC2250 were bulletproof, did nothing wrong, but ......, I prefer any of the tube amps I have owned or my friends own.

Klipsch, or other efficient speakers, so that eventually you might try a tube setup.

Size of your listening space?

You have a small rear port now, and the curved back of the Paradigms has to be helpful with corners, reflections. the Flat box shaped Klipsch and large rear passive radiator are my only concern regarding the Forte. I designed rear ports for my custom enclosures, they were great in prior space, plugged up in current space. 

@tomic601 In fact, the 240 has a THD of about .5%.  It does illustrate that specs are of little use when comparing amplifiers.  Ironically, some of the most sterile and unenjoyable amps I've ever heard have extremely among the lowest rated THD specs.  I do agree that the 240 is a pretty solid performance benchmark overall.
