Good tube preamp for McCormack DNA 500???

I just purchased a dealer demo McCormack DNA 500. I have decided I want to pair it with a tube preamp and I'm looking for the best fit within my price range ($2500 new or used). My research has uncovered a thread here on Audiogon that quotes the designer, Steve McCormack, recommending that any tube preamp paired with the DNA 500 (10k ohms input impedance) should have less than 800 ohms output impedance and the "lower the better".

Heeding this advice here is my top five: (1) Manley Jumbo Shrimp @ 50 ohms; (2) Purity One @ 180 ohms; (3) VAC Stantard LE @ 350 ohms; (4) Joule Electra 150 MK.II @ 400 ohms and (5) Conrad Johnson PV 15 @ "low" (can't find specs.) ohms. These are all currently for sale on Audiogon and are used except for new Manley J.S.

The rest of my system consists of Aerial 10-T speakers with mid-$$-range Synergistic Research cables and a highly modded Anthem CD-1 digital source. I prefer a warm, rich sound with no rolled off highs, mids or bass. Remote control is a must but I don't have a high care factor on balanced vs. single ended.

I would appreciate comments from anyone who has had success with a tubed preamp and the DNA 500 or anyone who because of their vast knowledge or experience with such matters cares to comment. Thanks in advance for you input!

There's an AudioPrism Mantissa preamp for sale here at Audiogon. That's what I use with my 500 and it is a wonderful pairing.

I'll second the service level (and build quality) of VAC. I have a VAC preamp and amp and not only do they sound amazingly beautiful, Kevin has gone out of his way to answer my questions even when I had issues with a subwoofer giving feedback...he helped me trouble shoot it, whereas the subwoofer manufacturer watched on the sidelines.

I use a Marantz SC-7S1with my DNA500 driving B&W 803D speakers. I was looking for a tube pre at the time but could not find what I wanted in my price range of about $3000. I found a good deal on a JC-2 but the seller would not ship to Canada. I bought the Marantz thinking if I didn't like it I have a friend who would want it because he loves their products. Long story short I am very pleased with this combination. Prior to the Marantz I was running directly off the variable out of my Wadia player but found the top end somewhat thin and overbearing. I found a warmth and lushness that I only thought I would find in a tube preamp. Level of detail is great as is the soundstage.
