I’ve got a total of 162 hours on my BHK Pre. I’ve listened to it, Roon -> DS feeding, M700 driving, for half of those total hours.
One true measure of a system for me is does it (continue to) sound good when turned down to ~50dB SPL? The BHK Pre along with M700 has the SGCD and S300 totally beat.
I’ve only run the stock tubes so far.
I’ve got to plug my speakers, built by Dave Fabrikant San Clemente, CA with Seas drivers and RAAL ribbons, Ascend Acoustics Sierra 2. I’m just a very happy customer from 2016.
I often forget about my pair of Rythmik L12 sealed servo subs in the mix too. They do their job without ever calling attention to themselves, but when I take them out they are certainly missed. I take them for granted while the BHK makes them sing or kick or hit, whatever is called for.
