$18k Tube preamp for large scale symphonies please

I respect the willingness of various posters here to offer suggestions and sonic descriptions, but, at the risk of repeating myself, so much is about synergy with the rest of the system, once the basics are nailed down, and dependent on the listener's own biases. I can't imagine trying to understand the nuances of what gear at this level sounds like in an appropriate system without hearing it for yourself, in your system. And I agree that tube rolling can make a huge difference, which just adds another variable to the equation, but one that can be fun.
Good luck.

Jwm, pretty sure we will have at least two types of cables there. They will both be about 40 feet long. Would that be sufficient for you?

Yes we will talk at the show, thank you.

Philipwu, I heard the Doshi with a Doshi modified tube amp and horn speakers. Speakers are 105+db and it was very quiet. Typical horn strengths, dynamic, transparency, detailed, resolution, imaging ... I did find the sound a bit thin, bright and too analytical for my taste.

I bought my Vac new and Doshi has similar retailed price. Unless one much prefers Doshi sound over Vac, IMO, Vac is better value. Doshi looks like a homemade DYI project, not balance design, no features and much fewer connectors and no remote.

I have a TRL amp and other stuff but no Dude. From my experience with TRL, you can't go wrong getting a Dude plus Paul is a pleasue to deal with.

I think you need to narrow the pool of pre with a list of requirements besides just sound.

My list was:
1. Output impedance
2. flexibility - tubes easy to roll and number of tubes. Once I had pre with 12 tubes and it was expensive and impossible to find 6MP of rare NOS. This requirement ruled out Einstein and Shindo.
3. features, number of input and output connectors, remote ... I only use XLR.
4. relative value to competition.
5. reputation of the company.
...

dear members, Merry Merry Christmas to ALL, and enjoy more music, more songs. HO..HO..HO...
