I had an SLI-80 for a couple years that I ran with Merlin TSM-M monitors and a Linn Sizmik sub. The sound was very clean and revealing with plenty of punch on the low end.
Before you go spending a lot of $$$ on new speakers, interconnects, speaker cables etc, consider these two suggestions to get more punch in your low end. Short term solution - replace the 6550 power tubes in the SLI-80 with KT88's. The KT88's are noticeably better in the bass and will give you a bit more slam. Long term solution - invest in a subwoofer. Make sure you get one that has A LOT of flexibility in where it crosses over. I have purchased and then sold more gear than I would like to admit :-) but the one component that is steady in all my rigs is my subwoofer.
Good luck!
