Owned the Rogue 99 magnum and now own the Chardonney.
The Rogue was big sounding had good dynamics and detail, but it sounded a little noisy to me and did something weird to the soundstage. Hard to explain. The Supratek is far better in my opinion. I had a problem with the power switch breaking and emailed Mick. He sent me one for no charge. Took a couple of weeks to get, but no problem there. I did solder it in myself. I also owned a Modwright preamp 9.0 with upgrades that I liked very much. I had both the Suprated and Modwright in my system for about a year before I decided to keep the Modwright. The Modwright is also very good and can be found inexpensively used. It was a little more extended on top with better dynamics. The Supratek was warmer sounding and bigger sounding with the 6sn7 tubes. Check the thread out on preamps costing $3500 great suggestions there. Don't know if you want remote or not but there are some excellent preamps for less like the Mapletree and the The Cary Ae-3 (the SLP98 can also be had in your price range)Since you are running a tubed amp the Modwright may be really good for you.
