@thoft, I remember Stereophile giving something of a mixed review of a Lazurus hybrid preamp in the mid 90’s.

You’re much more trusting, and willing risk taker than I am.
If you’re really looking for an amp to drive the 3.7’s for less than $10K, why not use the main one that Jim Thiel used when developing the 3.7’s: Krell FPB 600 ? You can find one used and have Krell rebuild it for about less than that. If you’ve got a smaller room or budget, you can go with a less powerful version.
