Suggestions for a holographic preamp?

I’d strongly recommend considering the Vinnie Rossi Brama preamplifier. It’s an exceptional piece of gear, built around 300B tubes in the output stage with a hybrid topology that allows you to run it fully tube, fully solid-state, or a blend of both—offering remarkable flexibility. This is ultra high-end equipment, unmatched in today’s market in terms of design, craftsmanship, and sonic performance.

Vinnie Rossi, the founder and designer, is a brilliant engineer who stands firmly behind his products. His preamp is known for delivering a stunningly holographic soundstage, with a level of refinement and dimensionality that would complement your MSB and Marten setup beautifully. And since you’re already leaning toward a tube sound, this would give you that lush, spacious presentation while also offering options to tailor the voicing to your taste

Absolutely agree—I’ve sourced NOS Telefunken tubes for my Luxman phono stage from Brent Jessee, and while they’re certainly expensive, the sonic improvement is undeniable. In my experience, if you’re pursuing a tube preamp, NOS tubes can dramatically shape its sonic character

Totally understand the budget constraints—but just a heads-up, you can actually save a lot by going for a first-generation Brama. There’s one listed on US Audio Mart right now for $20K. I’d consider offering $10–15K and see if the seller bites. These units come with a 10-year warranty, so you’re still well covered. It could be an incredible value if you’re looking for that top-tier tube pre without paying full price
