Some folks have concluded that most of the benefits of 'tube' in your system is their existence in your amps. Tubes in pre-amps and sources has as much to do with tone, bloom, air, etc, which will not pass unscathed thru a SS amp. I tend to agree with them, and see the comparison/result of using a SS pre-amp to be comparable to using a properly matched and set up passive line stage, only the SS might add a bit of 'drive' if you need it. If I could only have tubes in one place it would be in the amps.
Stanwal is right, you have nothing (except a few bucks) to loose if you don't like the sound and either decide to sell or get a pre-amp with tubes to get a better/different tone.
But, FWIW, re tone, before you buy the Rogues as opposed to any amp, consider their tonal signature and how they will interface with your speakers. Tube amps are not all created equal - there is far greater divergency between them from each other than comparing one ss amp with another ss amp.
FWIW.
