How does it sound?
Better than the EH for sure but likely on the par with other REALLY expensive 300B/300B equivalents I've tried (WE and EML).
Still...
Most detailed preamp I've ever had in my system.
But then I'm pretty used to typical 6SN7 gain, 6SN7 or equivalent cathode follower output type preamps.
Lite Audio Kit and deHavilland UltraVerve are my two prior preamps and those with NOS 6SN7s of just about every variety, TungSol Black Glass Round Plate, Sylvania big boys, bad boys, tall boys, RCA, you name it I got it.
They all sound a bit 'mellow' in comparison. You know you are listening to TOOOOBS!
Love to find a way to mellow the BeePre out a bit while keeping that new-found detail.
So, if one likes detail, and I'm guessing accurate, this is your preamp.
