The preamp costs 11K US. "A small, nine-button plastic remote handles input, volume, "Presence," mute, mono, and gain." Why do so many costly upscale bits of hi end equipment come with cheap remotes? Is this one even backlit? It always reflects negatively on the perceived value of a component. You don't get faux leather seats in an upscale Honda.

... line-level preamp in perspective is to consider that, for essentially the same price, one could buy both the Luxman CL-38uC preamp and the matching MQ-88uC power amp or the McIntosh C22 preamp and the MC275 power amp.
Both preamps include phono stages that can accommodate MM and MC cartridges.
KM should do a review of either one or both combos in comparison to his Shindo set-up.

I don't get it. I have been buying and using very sophisticated electronic equipment for decades and I never once had a manufacturer say you have to run it 200 hours before it works right. Not only does this equipment cost more than a lot of audio equipment but it goes down to levels well below human hearing.
This is why I want DBT. I want someone to prove that they can hear the difference in two pieces of audio equipment (except speakers) comparing out of the box to run 100 hours. I want people to prove they can hear the difference in cables in a DBT too. So far no one has been able to.

I like the subjective opinions, but it should be backed up with some DBT. Trust but verify. If the $10K pre can't be distinguished from the $1K pre, from a pro reviewer with golden ears, then why spend the money?
