Rogue Audio Sphynx and Martin Logan Odysseys


I was awe struck by this amp when I auditioned it 2 weeks ago and bought it while at was at the dealer's shop. I hooked it up at home to Martin Logan Odysseys and was completely satisfied except for a somewhat muddy sounding bass when listening to low passages of Michael Hedges' guitar music and other similar music. I was told by someone quite knowledgeable that the best way to tighten up the bass is to bi-amp using at least 200watt amplifiers. The preamp of this integrated unit is one of the best I've owned and I don't want to change the amp but it does not have pre out capability. It may be time to change speakers, and I would like to trade them anyway, unless there is another approach that will get me where i want to be without losing this wonerful amp. Any suggestions will be appreciated.

In all my years of audio interest I've never used spikes so I have a drawer full of them. I guess I just didn't understand, and am still a little fuzzy, how this seemingly simple application could accomplish much. Anyway, I appreciate your knowledge and experience so will continue to try understanding the rationale. I'm trying not to sound hard headed about spikes and I do like the idea of using "pucks" of some sort under the spikes but wonder what would be accomplished by moving the interface between the speaker and floor to between the puck and the floor. As a matter of fact, it creates 4 extra points of contact using this method. BTW, I do have the owners manual but didn't, obviously, heed ML's instructions. I'm going to try soft feet because I do believe that it will result in more solid contact than the flat floor to flat speaker box, because neither are truly flat.

BTW, both Rogue Audio and my dealer agree that this amp with a damping factor of 1000, should easily keep the bass tight, everything else being equal.
You have spikes and choose not to try them? As for an uneven floor, spikes can be adjusted (how far in you screw them) so the unevenness can be corrected for.

Spikes are the recommendation of your speaker manufacturer. Take em out of the drawer and try 'em. Doesn't cost you a thing.
If I decide to use spikes it won't be until after everything else is tried and adjusted and, even then, it will not be directly into/onto the floor. I had spikes on a Vandersteen sub a few years ago and it did cause damage when I tried moving moving it to accommodate new furniture. I'm 71 years old and have some significant difficulty lifting these things straight up to minimize damage to the floor so some compromise is necessary. After all, my whole listening area is already a compromise. Btw, I'm starting a new thread because I just discovered that one of my speakers needs a new transducer I think. Talk about a pain in the neck.
This is jimbreit but I had to do some changes to my ID and password to gain access again to the forum. Anyway, it looks like I'll logging is as "broadstone" which was my iD in 2005.
I reconsidered my decision about the spikes and realize that I have been ignoring an important part of setting up. This morning I grabbed a speaker at its top and moved it back and forth and am amazed at how easily they rocked and how pronounced the movement is. That HAS to be a problem. I am going to try soft feet first and make them adjustable to compensate for any floor irregularities. I know it's probably not the best way to go about this but these are new floors and I don't want to do to this one what I got in trouble for with the old floor. BTW, we didn't replace the floors because of the spike damage; we had a minor flood in another part of the house which required replacing flooring in 3 rooms.
