Sonus faber choices - help me decide

I've heard both the Amati Futura and the Olympica Nova 2. The former was the most astonishing audio experience I've had, beyond marvelous, but the electronics were a lot of money too (like 35000 - 40000 Euro retail in total). I mean no offense, but your current electronics will most likely not be up to the task, so this makes sense to me only if you are planning to upgrade (and I mean substantially upgrade) your electronics too. Also, the Futura tweeter is more reserved, depending on pairing they could be a bit dark.

The Olympica Nova 2 was almost as nice in the mids (but not quite), which still reads as "great!", had exceptional, sparkling but smooth highs that I really loved, more so than the Futura's (and definitely not as subdued), and rather ambiguous bass even driven by the same Accuphase E600 amplifier that drove the Futura's quite well. Maybe it was the positioning, maybe the lack of burn in, maybe it's just that the single 7 inch bass driver is not quite up to the task (or to my expectations). I'd consider the Nova 3 instead. Oh, that tweeter, lovely! Also, maybe the need for upgrading the electronics would be a bit less stringent that for the Futuras but still very important I think.

Another thing to take into consideration is the availability of spare parts. I've considered the Futura myself and I emailed Sonus Faber to inquire about this matter. Disappointingly, they directed me to the local distributor, as if the spare parts policy would be the distributor's! It scares me to think I could buy the Futura's, have a tweeter accidentally damaged someday and be left out in the cold!

Thanks for the feedback. I share your concerns about the electronics. My plan was to eventually upgrade them via the secondary market, but that will take a while.

I had not thought about the spare parts. I have never had a speaker break on me, so maybe that was why I had not thought about it that way. How much should I worry about that?

I am fairly new to this hobby. I have always been passionate about audio, but previously did not have the means to spend what it takes to achieve audio nirvana. Those Futuras look like an end-game speaker to me, but I wonder if they are too big of a mountain to climb!

One more question. Assuming I stay in the Nova line, my decision to go with the Nova II was largely because I have subs that will handle the last octave. I didn't think paying $5000 more for a a ~5Hz difference was worth the money required to step up to the Nova III. Is this logic sound? My assumption is that the only difference between the II and III is bass extension. They have the same cabinet, tweeter, and mid-range driver, after all. The III just has one more woofer.

-Well both will be much better than the B&W CDM 9NT so no worries there but if you have the means always buy the better speaker.  Futuras Is an endgame speaker IMO  

-the first question I have is how do you use your subs? Do you highpass (cut the lows to the mains) if not you should be. This will play a big part is what way to go. The main difference between a lot of speakers is just the bass and if you are cutting it off anyway it matters a lot less.
 
-the soundstage and inner detail will most likely be stripped out a bit by the denon it will just sound like it has less scale. I also have a combination two channel home theater and speak from experience (I have had many systems with denon, marantz, b&w 703s (newer version of your speakers) and I run duel subs (picture of my system in my profile). Anyway the kicker is you probably use your denon for bass management and that will make it hard to go to a two channel pre-amp if you ever want to (you should) because you would not only need to bypass the surround through the two channel pre amp but also through an external crossover. For what is is worth I do just that. Have a two channel preamp/amp with “external” crossovers in the subs and bypass through the two channel system for home theater. Works great, best of both worlds but is a lot of wires and equipment. Also family members will never be able to turn it on again, you can decide if that is good or bad lol. 
 

I cross over the subs in the Denon @ 40Hz. The CDMs go down to ~38, so I thought 40Hz would be a good choice. I have experimented with higher crossovers, but don't have a real preference. At one point I ran Audyssey and told it that I only had two main speakers and was shocked at how great the bass was from the 9NTs (without the subs). I was still missing the deep lows, so I eventually did run it again and tell it I have subs. That is where I am now: 2.2 on Audyssey Preset 1 @40Hz. Preset 2 is for my 7.2.4 setup.

I have my eye on the Anthem STR integrated amp. It has ARC and supports bass management. I figured I would use the HT bypass for the main speakers and then do a bunch of Y splitting for my subs. I assume the Anthem would integrate the subs similar to the way the Denon does, and I would not blow up my subs by having them connected to both amps. I would just turn off the Denon when I'm running two-channel (and vice versa). The good thing about the Futuras is that they go down to 25Hz so I would not even need the subs in that configuration.

Given that, I still wonder if I should shoot for the higher-end speakers. Would the Anthem drive them appropriately (Stereo integrated amplifier with 200W/400W/550W into 8/4/2 ohms)?

I need to make a decision today. The Nova II's are on order and I need to tell the store if I am going to cancel the order. The guy with the Futuras will not have them forever. I'm assuming they will be snatched up soon.
