What's the best preamp for under 1000

I think a used Sonic Frontiers Line 1 is a good choice. It is not as transparent as the Placette (but almost) BUT, you get ALL the features one could possibly want in this price range and more. A cool, round aluminium remote. H/T loop, phase inversion, mono switch, configurable inputs, and the list goes on and on. The exact same chassis, solid build and styling as the $5K Line 3, and it's an easy choice. I am finished buying high-end gear at high-end prices that do not come with a minimum of conveniences and adjustements....

I also recommend the CJ PV10B. I started with a 10A loved it and ultimately ended up with a CJ premier 16 series II.

I'd add the Audio Research SP-9 to the list if a phono stage is needed. All versions can be had for less than $1000, I would go for the latest MK III which is the best sounding but a little harder to find (there was one listed recently in the $800-900 range). When it comes to relaible service, holding value, and of course good sound Audio Research is a good choice. Of course there's nothing wrong with any of the other recommendations. As has been said many a time the best is very system dependent!

For an active preamp, the original 6SN7 based Blue Circle BC-21.

There is also the earlier CJ version; the CJ PV-10A, which is similar to the new B model.

There is a plain PV-10, from 1989-1992 which was my first tube preamp. It uses different tubes then the A and B versions.

If you're going to look at the CJ's , also look at the Audible Illusions(L-1 linestage and M3A w/phono) It is still one of the best sounding preamps out there but often overlooked. Make the comparison for yourself!
