Benchmark LA4 preamp Stereophile and Absolute Sound, sounds like it is pretty much a passive preamp??
Why pay $2600.00 for it when the Goldpoint passives above are approx $500? depending on how many inputs needed.
Don’t know a single person who has kept one though.I know many that have dumped their $KKK dollar active preamps for them, just mine alone that has only one input, is nudging up to 1k world wide now.
And going direct source to amp is just a bit better again, if not "bit-stripping" by having the sources digital domain volume too low.
There is a few posts in the LA4 preamp thread today that gives some examples of the quality of the LA4. You got nothing to lose other than $2500 if you do the 30 day free trial from Benchmark. I use a HPA4 with a few analog sources including a DAC.
Wow, did not realize the HPA4 was Product of the Year for 2019. It is marvelous with headphones.
