Rogue Magnum 99 question

I have just purchased a new Magnum 99 to replace a AES AE-3. With only 2 days out of the box I honestly dont know if I like its sound; given it is new and needs time to break in and the cheap NOS russians need to go. I was using a pair of Sylvania chrome dome in the AES and loved their sound.
Did anyone feel the same as I do? How long did it take for the 99 to break in? What tubes did you roll and find good results with? Are the russian 6sn7's a very poor link in this piece of equipment that they hinder the preformance? In what order do you start rolling.....front pair,rear, or left, right....instuctions really dont say. I also have a pair of KenRad VT231 blackglass that I really didnt quite care for in the AES.
Any helpful suggestions or comments would be appreciated.The 99 is mated to a Bryston 4Bst.

thanks, kek

Kek,

I was pretty happy with my Rogue Magnum 99 right out of the box and it has only improved with use (~100 hrs now). I didn't perceive any significant sound change after ~25 hours of use. There was some tube break-in apparent over this time. My unit came with Electro Harmonix 6SN7s that many people claim to be one of the better currently manufactured tubes. I have not tried NOS 6SN7s yet in the main preamp but have rolled to Mullard 12AX7 and Amperex 12AU7 tubes for the phono stage and they made a significant difference. If you do some 6SN7 tube rolling, I would be very interested in the results.

P.S. The rest of my system is Magnaplanar 1.6 speakers, CJ MV50 amp, Audio Aero Mk 1 CDP, Nordost Quattro Fil interconnects, Acoustic Zen Satori speaker cable.
