Majestic 745s and PS Audio BHK 600?

I use PS Audio BHK 300s with my SoundLab Ultimate 845s with excellent results. I do occasionally have the protection circuit kick in when playing program material wit very high frequency content quite loud (Miles Davis well recorded trumpet blasts) but do not find it particularly objectionable. Soundwise they work very well. I also use Atmasphere MA1s. Also excellent but very different sound

Hello Jeff,
I looked up the manual for PS Audio BHK600 – see attached.
It says that it is good down to 2 Ohms for musical transients …

I am surprised that they responded to Keith that they could not power the Sound Lab, except that there is a very high likelihood that they do not know how easy the Sound Lab is to drive (since newer versions after 2006-ish, and especially after 2012)

There is, however, one possibility that they have a overly-sensitive protection circuit – and because Sound Lab’s are so fast to respond to music signal, they demand the fastest response from amplifiers – some amps see this as a ‘threat’ and go into protection (turn off for a few seconds and turn back on usually)

Let me know if you have any other questions – I actually use a 60W David Berning amp and it performs amazingly and I can get 90-95db response from Sound lab’s largest panels in a large room…And Benchmark AHB2 never ever misses a beat.

I was considering the PS Audio amps, as well, with my Ultimate 845’s. I called PS and they said that their amps would not properly power the panels. I was kind of surprised that they were so forthright.

But… I’m now using four subs with my panels which may open up opportunities for “lower” powered amps now. I’m currently running Sanders Magtech amps to good effect, but I’m looking for some tube juiciness.
