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.

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.
I had an LS3 and liked it...liked it better than an Audible Illusion 3a and a Conrad Johnson PV (3?) I compared it with.  Nothing romantic on sparkly.  It was feeding a McCormack DNA-1 and just sounded solid, full and balanced. But it's  the only AR I've owned.
I agree with both of the LS17SE owners, which I own also, I had a Dodd buffer with the 6H30 and liked it compared to other tube pre's I owned, less noise great sound stage, reliable and long lasting tubes. I compared it to a Wyred 4 Sound STPSE and liked what it did for the sound better than the almost passive Wyred. Also fully balanced, Great buy right now.
