NAD M3 versus Simaudio I-3 SE

I had the I-3 (regular version) and I-5 also for a couple of years (one year each). Now I have the M-3. In global terms, I-5 and M3 are almost in the same level with some differents, both betters than the I-3. I-5 is warmer than M-3 and M-3 has more power and better management of bass. For my system with very revealing speakers M-3 match better than I-5.

I used to have a Sim I-3 (regular version) in my set-up, then after trying out several other amps, I settled on a NAD M3, so my impressions aren't side-by-side, and should probably be taken with a grain of salt. That being said, I found that the NAD was simply much better than the I3 in all respects--resolution, soundstage, pacing, etc. Of course, given the respective price points for these amps, that's probably to be expected, and I do think that the I5 might be more comparable to the M3. The M3 does output well over double the wattage of the I5, though...

okay... last question. thanks for bearing with me. What about the M3 compared to a simaudio I-5??

Thanks

Has anybody here listned to the M3 and a rotel. I have a rotel ra-1062 currently. Was wondering how the performance at higher frequencies compares (I know the rotel is a much cheaper amp).

My thought is if your speakers tend to the brighter side then the NAD will be a good offset to that; if not, then you'll be dealing with some restriction in the upper mids and highs.

Thanks for the responses. I have T+A talis tls1 speakers. My greatest worry is the way some people describe the M3s high end as sounding introverted. However, synergy (as foster_9 mentions) is not factor I have considered yet.

I had the M3. It is not the last word in having an open airy high end. I never used the treble control but that might help with that. The M3 is sort of closed in the upper end. I haven't heard the I-3SE but from my reading, it is very different from the M3. The M3 would probably be a bit rolled off in the upper mids and highs compared to the I-3. But, the synergy of your speakers with either integrated (the strength of the match) will be also be very important.
