mo' better bass: any substitute for watts?

as a general staement, a more powerful amp will deliver more bass at a lower volume. speaker placement can help too.

I have found my digital Super T-amp really brings out the bass from music, without having to turn it up loud. And it is only 6 watts a side at 8 ohms. I also play it directly from my Oppo 980, as it has its own volume control. Try a digital amp for fun.

Generally speaking, a more powerful amp may give better bass but it also depends on the character of the amp itself. I am pretty sure you will get better and more defined bass if you substitute your 35W NAD amp with say a Krell integrated. Also, Jaybo is correct in that you won't need to crank up the volume higher to appreciate more bass with a substantially more powerful amp. Even that, your speakers may be limited in bass response, and the suggestion of adding a subwoofer is good idea if the frequency range of your Rega speakers does not extend down to 35Hz or so. Adding a more powerful amp won't help much if your speakers ain't up to it.

Ok, fourth time trying to post to this thread. I'm surprised that you haven't been asked yet what speakers you are talking about? Also, this could just be a placement issue. Have you moved your seating position and speaker position around enough to rule this out? If you do not already own the oppo 980 I would suggest getting the new 983,it has better sound quality from the analog audio output.
