Suggestions for a holographic preamp?

This has been my experience.  If pursuing a tube preamp you can significantly change its sonic characteristics by using NOS tubes.  This has allowed me to spend thousands less on the preamp itself and spend $500 on the primary preamp tubes.  These vintage tubes are much better at producing a holographic soundstage than any new production Chinese or Russian they put in today’s preamps.  I have used Brent Jessee to guide me on what matches my preamp but there a few others with experience and a good supply of vintage tubes.

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

The humble Topping A70 Pro is the most holographic preamp I have owned among  many, including tubes and SS. 

Spend the $9500 you’ll save on a nice vacation or some ETFs. 

More money ≠ greater performance any longer when it comes to preamps. 
 

@triton20trx and @ei001h - thanks - I know about tube rolling; I've upgraded tubes in both my Herron components and in my 2 tube headphone amps, including one with a couple of WE 300B's in it (and those were well worth the $1200). And yes, when I'm looking for a tube upgrade, my first stop is generally Brent Jessee. Been going to him for a lot of years now.
