This is the data sheet for BP’s Hypex ‘400’ amplifier module (performance graphs at bottom of page)
http://www.hypex.nl/docs/UcD400_datasheet.pdf
(note, e.g.,  the THD vs Freq. plot—ruler flat)



Because he puts the output filter in feedback.  Some thought this was impractical/impossible!

I'm interested in trying this BP amp, yet love the Pass so much, I imagine we'll be getting another one at some point.

Hi, Mark,

Thanks for the update on your system!

I know you are a perfectionist, and wonder if you could describe the differences the amplifier changes have made in your system.

Thanks,

Mike

I think I mentioned before about the Sax amps and becoming to expensive to maintain.  I listened to a bunch of amps (including the Krell) and as a pure listening experience I ending up with the Spectral 160S.

The honeymoon was over quickly because I felt my work dropped quite a bit.  Even though they were a good listen, I wasn't getting the feedback I needed.

We recently lost an engineer (Darcy Proper) who moved to Belgium to work at Galaxy Studios.  She had a 5.1 setup with Dunlevy and Krell's.  So, I decided to give them another go.  I thought the feedback was vastly better, even over the Sax amps.  My compression work is spot on now, and have much of my bravado back.

They're much faster than the Sax amps, loads of clarity in the bottom, the midband is complete.  I'm still playing with cables.  I'm sure the top will come into focus better once the cables settle in.

Lesson learned...The work system is not the hifi system.
