Can't speak to the Rogue, but previously owned the BAT VK30 and was disappointed with the sound (grainy and mechanical sounding), however the build quality and appearance of BAT gear is top shelf. I highly recommend the Aesthetix Calypso with NOS tubes... the best preamp I have ever owned, and quite reasonable used.
Rogue 99 pre vs. BAT vk30
Just curious what you guys thought about this comparo. I'd be using a Cary v12 amp and Maggie 1.6 speakers. Would it really matter that the bat has balanced?(cary amp does too) I love tube warmth and widest, deepest soundstage possible (even if it's inaccurate). So, which would you buy? Thanks
