I fully agree with your approach! Go as big as you can in the speakers. As a Vandersteen guy and as someone that used to own model IIs I'd fully support a pair of those. What I will say is you need enough space in the room to get them a few feet from the wall. The good news is they're very shallow speakers so it's not hard to get that front end away from the wall. If you do get model IIs definitely get the stands. I agree that it's likely that the marantz will probably do fine driving them, the adcom even better. But what I'll add is that you'll have significant room to grow. The speakers will keep getting better as you improve your electronics. I think the other benefit of a full range speaker over stand mount plus subwoofer is that the crossover is already integrated. It's much harder to integrate a sub than most folks think.
Decisions, decisions, decisions
I initially had a short list of potential speaker upgrades for my 2-channel set-up and I find myself in a bit of a quandry. I've narrowed the list down to 2 speakers and neither are remotely like one another. I currently have some mid-level Polks and they're "ok" in that they get the job done for low-level listening enjoyment but I really want to step it up a bit. I can justify $4K for my budge which puts me in a bit of a sweet spot for my preference for stand-mount speakers vs floor-stand speakers. However, my short list consists of either the new Sonus Faber Sonetto II G2 stand-mount or the Vandersteen 2ce Signature III. Because the SF Sonnetto II G2s are brand new, a used option is out of the question. The Vandy 2ce III's come up used occasionally but where I live, previewing either one is not a viable option because there aren't any nearby dealers. That being said, I can get both of these from Audio Advice. If I went with SF Sonnetto, I would probably supplement those with a subwoofer down the road after sometime. At that point, I'm nearing the price range of the Vandersteen's. The question I have for the forum is does anyone have experience with the SF Sonnetto II pre-G2 and what are your thoughts about them?
I have a Marantz integrated at 50W and my only concern w/ the Vandersteen's is not having enough power to get great sound out of them without adding an amp (while I have a vintage Adcom GFA-2 at 100W/ch) that I could use, I"m not against getting an amp for either the SF's or the Vandy's.
I listen to a wide array of music genres but lean towards rock, jazz, electronic/industrial, dub, funk, and classical with some pop and old-school country thrown in on occasion.
I've the impression that those with the Vandersteen 2ce's are very pleased with the SQ. But does anyone have experience with both speakers?
