Serious thoughts about Audio Research LS 27

I have owned one in the past.... if you like Audio Research sound, you'll like it.
I did...

Thank you gbryant.

And yes, I like ARC sound very much, I've owned an amazing LS 25 mk1 but I'm afraid that the LS 27 would be more similar to the LS 25 mk2 which should be more analytic than fascinating and emotional, with lightweight bass and fatiguing highs.

Could you tell me something more about the matter?

Thank you!

I had the LS25 Mkii and never really could love it. Maybe I was looking for tube warmth and this one doesn’t have it, the analytical description is apt. Of the ones you mentioned, I would go for the REF3

I'm dealing on an LS 27...

If the LS 27 doesn’t work out I think the Ref3 suggestion is a good one. I’ve have/had an LS25 Mk1, Ref 2 Mk 1, LS 26 and now a Ref 5. Parts quality is pretty good on all of them and the LS line stages are incredibly versatile, even more so than the Ref series. There’s not even that much compromise on the preamp stages themselves.

What the Ref series brings to the table over the LS series are big no/low compromise power supplies. Since the Ref 2 they’ve all been vacuum tube regulated with a lot of decoupling and bypassing and storage. There’s no way to put that much power supply into the LS form factor. My experience has been despite marketing hype it’s pretty hard to get an LS to beat a Ref. They’re probably creating the sound of the line stages with the power supply.

I will also say that the 6H30 based line stages are consistently quieter than the 6922 ones (my sample size is the 4 listed above). That would pretty much put the 27 ahead of the 25 Mk1. I don’t know how much difference there is between the Mk2 and the 27. I know quiet isn’t everything but it sure helps. Good 6922s are getting harder to find.

If the 27 is like the 26 it’s still going to be a really good preamp.
