The connection would be via a specially fabricated DIN splitter cable, and yes the speakers have 4 binding posts (Vandersteen 3A S.).
So it would be safe to assume Naim themselves would recommend the SN if they don’t recommend biamping, I prefer that route for simplicity’s sake but was wondering if the someone here had tested or had an opinion on the other (slightly more powerful on paper) option with separates.
The Vandersteens look like quite a lot of speaker, if they are the ones I’ve seem on line that cost $6,300. I certainly wouldn’t consider the 152/150 option with them. The Supernait is more muscular and a better match, though it would be very much a minimum. What source are you planning to use? Those speakers and a SN2 will need something pretty good.
Budget is of course a significant consideration here…so other upgrades are an interesting talking point but not an immediate consideration. That said at this time the sources are Tidal through an iFi Zen Stream and a Denafrips Ares II DAC, or At440Mlb > Systemdek IIX > Moon LP 5.3.
Current amplification is an Atoll pre/power combo (200SE), and the speakers are indeed currently being sold at 6300 USD but were purchased second hand for less than a quarter of that (they have been in production a long time). Used price for SN2 is really the most I can invest into my system at this time.
The reason I’m looking into this is I’m missing the sound signature of the Nait 5i, which I still have but is not up to the task with these speakers.
Thanks. Of the two options it would still be the Supernait I’d pick. Don’t think that having two 150s would give double power, because it won’t. Chris’s suggestion of a 200DR is a nice alternative, but if you went that way, the 202 is really the preamp to get. But the SN2 runs it very close, and many prefer the integrated. I’ve owned a Supernait 3 and it’s a very fine amplifier, just a little better than the 2. There is something nice about having aesthetically matching boxes; something you don’t get with a 152/200. If you went with the SN2, an NDX2 would be a perfectly matched source down the line.
