Audio Research LS17SE

There are some out there now and they have great resale potential so if you can get one at $2k, you could always sell if you changed your mind

Good point, and fine units. But if I recall correctly, they are from the period where Audio research started working very hard to make their tubed electronics sound like solid state. I need a bit of warmth in whatever preamp I buy, that's why I choose to use tubes. I did look, though, and $2600 or so seems to be about the bottom pricing on those.

For what it’s worth, I had an Audio Research SP-16 and a brand new Schiit Freya + for about 3 months. I did some critical listening and some tube rolling with both. I ended up selling the Audio Research. The 6sn7 tubes were just better to my ears. And when tube rolling, the 6sn7’s made a huge difference in sound. I ended up with 2 NOS GE’s in the buffer stage and NOS Ken rads in the gain stage. A sweet Lucious tube sound. Plus it had XLR’s out for my Krell amp. The Audio Research sounded decent but it was single ended, and new production tubes versus NOS tubes didn’t really make a major difference in sound.

Really interesting comparison Robby. Thanks. The sound signature you describe is right up my alley. Certainly food for thought. And I know Mike Moffat a bit, and always enjoy supporting his efforts. I just realized, from re-reading your comments, that the Freya preamp is a fully balanced unit. Which, unfortunately,as noted in my response about the VTL’s, is an issue.

@nightfall  The VTL 2.5, 2.5i are single ended. The VTL 5.5 and 6.5 are both single ended & Balanced. Not often you will find a preamp that is balanced only, ecept for some of the ARC models.

As far as age of VTL's, most people say they are built like tanks + we forget that most gear is built to last many decades. The good stuff anyway.

I swear I'm not a VTL dealer, I'm pumping their tires plenty.:)

I don’t know that level of detail regarding the sound ARC was going for between different generations. I have always heard that ARC is not a tubey sound but it is what I have had and never ventured out to compare with other tube models out there. There is one on US Audio Mart for $2250. Most people are willing to come down a little. It doesn’t have the original box which is a bummer but not a deal breaker. With heavy amps/preamps the original box is critical for shipping but these preamps are very light so could be well packed in a generic box if proper care is taken.  I would definitely talk to the guy and get pictures of his plan.  ARC puts each component in a thick clear plastic bag before going into the box.  What I have done for folks over the years when I didn't have that bag is take a roll of shrink wrap from harbor freight and wrap it up really well.  Have him use dense foam all around and not styrofoam peanuts...may seem like common sense but some people just don't realize or think about what can happen in transit so best to never assume.

+1 on Odyssey Candela tube pre. I believe one can be had new in your price range.  It stands up nicely with big hitters, driving a Pass Labs 260.8 into Wilson Sasha DAWs in my system. Basic remote available.
