Can someone give me an explaination re: power amp.


So, I own a simaudio i-5 driving paradigm studio 60 v.3, and I am not happy with the sound at low volume. turn it up everything is great, but low volume has muffled sound. Everyone says the paradigms are efficient, but i go out looking for more efficient speakers, and happen to come home with a loaner power amp- a simaudio w-3 (125 wpc), and the sound at low volume sounds markedly better with the power amp. this is contrary to everything i have convinced myself to believe. i have convinced myself that a good integrated is all i need, but I cannot deny the sound. so instead of asking the age old separates vs. integrated question, i'm just going to ask- why does my system sound so much better at LOW volume with the power amp. Maybe the speakers aren't as efficient as I thought? Maybe the 70 wpc simaudio i-5 isn't as great a machine as i thought? maybe there's a technical explaination? Please enlighten me! and thanks, and merry christmas to all you audiophiles out there! (oh, and the reason I didn't come home with speakers is that i really love the full range of sound from the towers, and i couldn't find any highly efficient speaker that had the range I enjoy. not that it dosen't exist, but i just couldn't find it. I live in portland, oregon).

okay. so it's an current/amps thing (at least in this particular situation). The thing is, I have a decent sized room, and i can handle full range speakers. for example, i listened to the ProAc Response 2.5 the other day, and I really really (i mean really) liked them. and regardless of where I go with this hobby, it's starting to look like a good high current amp is going to give me the flexibility to audition a wide(er) variety of speakers over the next few years. I think I can still get there with an integrated Kijanki, but starting to think a separate high quality amp is going to provide the most "room to move" over the next few years. I mean, lets face it, no matter what I tell myself, i'm going to be purchasing different items, micro-analyzing my system to death, for a long while- i just can't help it anymore. i give up. :)
I used my simaudio i-5 integrated as a pre. The sound and low volume was much clear and clean. background instruments and vocals were audible. My girlfriend and her 8 year old son both thought the w-3 sounded much better, and they are not very critical listeners.
for the record, i don't see the connection either. if i did, i wouldn't have started this thread. i really don't understand why it is the way that it is. thus, the post.
ball parked the volume issue, but feel that I over compensated (turned the volume way up) when listening to the integrated, and still experienced better sound with the w-3. with everything i know about high power and/or high current i agree they do not offer a rational explaination. however, there may be things I don't know about high power/high current that may lead to a rational explaination. this is what i'm trying to find out.
