Used Audio Research Preamp Options

Before I pose my question, I do admit that I expect mixed responses since the question is somewhat subjective. That been said, I think I have pushed myself into an obsession to own an Audio Research preamp. I know there are better preamps out there for the money and I might ultimately overcome this obsession but I'd like to hear from folks who have owned different ARC preamp's over the years about their personal experiences. So here is my question: if you had $2500 to spend, which used ARC preamp would you buy? A line stage component would be fine, tube or SS. I'm also making an assumption which may not be completely valid and that is any of these preamps will be an upgrade from my NAD C165BEE. Any comments will be appreciated here too. My other components are McIntosh MC2200 (100K impedance) and a Vincent SP-331 ( 47K impedance,150w in 8 ohm/300w 4 ohm) amplifiers. Not sure if speakers matter- ML Aerius, Def. Tech. BP20 since I'm also looking for an upgrade route there too. Thanks.

I read about the "direct" option when researching some of the older ARC models like LS3. According to ARC, the Direct mode provides the highest level of resolution when using high gain line stage components such as CD players, etc. Not sure if it acts as a passive preamp or not. I'm sure there are folks who know this model and can comment.

I had the ARC 40th Anniversary Edition and now have the ARC Ref.  If there is a better preamp, then I haven't heard it.  I was at the Munich Hi End Show in May and had the pleasure of listening to some stellar pre's.  Still put ARC at the top.  In short, your obsession may simply be good taste.  Enjoy.

For that sort of $, I would expect no less....Fortunately the closest ARC dealer is about 50 miles away from me so I'm somewhat guarded from completely destroying my enjoyment from my current system...

I checked the ARC LS3 owner's manual and found that the Direct/Normal switch acts as described above and bypasses the Balance, Mode and Input Selector switches.
As I recall from when I owned an LS3, there was no great sonic difference using the Direct Mode vs, Normal. This is probably because you are still subjecting the signal to some of the preamp's electronics and therefore this is not a truly passive line stage circuit.
In any case, if you want a preamp vs. a passive line stage, this should not be a deciding factor as to which preamp to purchase.
