@azwill I used the Tambaqui with a preamp. About 2 years ago Vivid changed distributors and went to GTT Audio who happens to be the Mola Mola distributor. They offered to keep me on but after reviewing the dealer agreement I declined because I would violate it. They prefer people to sell in a specific territory and I live 1 town over from GTT who sells direct. Just not a fit.
This forced me to alter my reference system and I recalibrated my testing. The current system is as follows excluding DAC.
Canor Hyperion P1 Preamp
Canor Virtus M1 Mono Blocks
Wilson Benesch Discovery3 Zero Speakers
Antipodes Oladra Server
Inakkustik 4004 speaker cables.
Clarus Crimson XLRs
Puritan PSM1512 Conditioner
Puritan Ultimate XX PCs except for Preamp which is an Inakustik 2404
i specify any deviations from this setup when I write something up.
