What's your "diminishing returns" preamp choice?


What preamp would you consider is at the point of diminishing returns for you? I realize this is a vague and subjective question, but I think it will be interesting to hear the answers.

Of course, a $10,000 preamp will (probably) sound better than a $1,000 preamp but everyone has a different point at which they feel they have spent enough money. In some cases, one may feel that there isn't a significant difference between a $2k piece and a $10k piece to justify such a purchase.

I've noticed that there are some gems in the audio world that defy their price point. For instance, Apogee Centaurs, Halfer 9505 etc. I've always found such pieces fascinating.

I'd probably get Lamm or Gryphon thinking of either as the best value too, and be happy ever since. Or maybe older top of the line Rowland.
I've seen $2000 preamps take $13,000 preamps and eat them for breakfast- better in every way.
Tell us more please @
I’m not sure, how much is a CAT?

I ask this because I've heard different but never have I heard better.
@gochuchgo There are a number of single-ended 6SN7-based line stages I've seen that do the job.
