I have NOVA V's and I am not happy

Those older Nautilus 800 series B&Ws actually measured fairly flat compared to current models and were arguably better speakers than the current series.

As for the SFs, I auditioned the Nova IIs and thought they were quite neutral. They were being driven by a relatively entry-level integrated though. 
 

I wonder if what you’re actually hearing is cone breakup from the midrange driver. It is absurdly common these days for manufacturers to fail to design a proper crossover network for the driver limitations. Even brands like Revel and Dynaudio have been guilty of this in recent years. They don’t low-pass the woofer or midrange cone at a low enough frequency so you end up hearing cone break-up distortion when the speaker is pushed, often in the 2-4kHz range where our hearing is most sensitive. I’m not claiming that’s definitely the issue with your SFs but it’s very common throughout the industry. No good excuse, just lazy engineering.

Anyhow, just a possibility. Also, as others have alluded to, some amps really struggle with the high capacitance of Kimber cables. I wouldn’t expect that from ML amps but something to experiment with. Supplementing some hardware store zipcord will be sufficient for determining whether it’s the Kimbers.

@mckinneymike Good luck in your search. There are a lot of options and I was in a similar situation about 10 years ago. I was very unimpressed with many speakers that had strong reputations - B&W, Mission, Martin Logan and others were close but there was something missing. 
 

And I have noticed my tastes change. I was really happy with both NAD and McIntosh previously and now I am much more drawn into Moon and Audio Research. 
 

I encourage you to create an audition list of music you like and have listening sessions at retailers and if possible friends systems. 
 

good luck

I have these speakers paired with a McIntosh integrated amp and they sound sublime. 

I’d add that my integrated has a EQ controls which gives me a lot of tonal flexibility. 

The first place to start is as Eric suggested: eliminate your room effects bye setting near field (only 2 - 3 ft. from the front plane of the speakers. Adjust the volume to the perceived level you prefer to listen, and what you hear is, sonically, how the amps, speakers and cables are working together, at the volume levels you prefer to listen - with little to no influence from the room. If the tone, texture and balance of highs, mids and lows is what you’re looking/listening for, then you’ll know that what you have will work with optimal speaker placement and room treatment.

Listening at those higher volumes brings out the worst in a room and increases the need for dampening and other treatments to reduce the reflections and oddities that can raise such havoc with the balance, tone and musicality of a great system.

For serious listening, it would help a bunch to put a blanket in front of the TV screen and move the speakers out further from the wall and experiment from there.

Best of luck........Jim
