Will increasing size of amp improve sound quality?

As a previous owner of several Rotel amps, the answer is NO. Move onto something else. I also agree with Drr, upgrade your speakers one day. Read the speaker topics for ideas.

Upgrade the speaker crossover networks will completely improve your speakers. It is easily the best thing I ever did for my audio systems.

I upgrade the Klipsch speaker crossover networks if you're interested.

Thanks to all of you who thus far responded to my question. I am so new at this that I am easily confused. I looked into the Sonus Fiber speakers. Which ones would you recommend? And, I wondered if they are priced by the pair or singly. Bartokfan mentioned moving on. Had you had a bad experience with the Rotel?

Vman: I will show my ignorance. What does it entail to upgrade a cross over network?

Jnorth,

With the Klipsch speakers, the majority of the improvement comes from upgrading the caps, resistors and in some cases the iron core inductors. It's not a very difficult thing to do and it greatly improves any Klipsch speaker.
