New MSB S500 and M500 Amplifiers

Where do you even guys see a heatsink or a meter ? Are we looking at different pics ?

It was requested that I remove the prototype photo because it was misleading. In the final design, the heat sinks will be much larger and the remnants of the meter will probably be removed. I will post a photo of the final design as soon as it’s available.

Concerned about its form factor; hopefully the feet will be no deeper than 16" - otherwise it won't fit on the platform in my audio rack... :(

OMG, I hope not. But I was actually wondering the same thing. It certainly looks like it could be a fan assembly.

Hi Ken,

Why would you hope not? From the pictures of the Prototype casework there does not appear to be any external heat sinks or venting. Yes that is a mock up in the pics but there may be intent to keep the outer case smooth and homogenous without cut outs? If so, they would need to move heated air out of the interior of the chassis somehow, no?
 
Is that a fan in upper left under the round cutout?

I spoke with MSB regarding the fan question and here is their response:

“Absolutely not! That is the bracing for each of the two transformers. It will have two massive heatsinks machined here in our shop. Working on those now.”

So a smaller transformer for the input/control section and a big boy for the output...nice!

Hi King,

You may be right but looking at the photo of the M204 monoblocks from MSB’s website suggests that the two transformers could be identical in size. Maybe one transformer for each channel on the S500 Stereo Amp.

Hi Ken


The upper transformer looks smaller than the one under it but who knows...time will tell. Sure glade to hear there is no fan!
 
Hello Gentleman,
I just joined here to comment in this thread. I own a fully loaded Diamond Dac 4 with the Signature Data Cd 4 transport with separate power supplies. When I bought them I was using the Krell Evolution1 power amps.
Vince convinced me to buy the 203 monoblocks to replace the Krell's. Krell has a reputation for great bass, and the Evolution1 delivered. When I considered the 203 I read up about zero feedback amps.
They sound great, can be hard to keep stable with the bass being alittle tubby. I bought them anyway. They were alittle tubby on the bottom end compared to Krell, but everywhere else; they destroyed the Evolution1.
The next year I upgraded to the 204's and was assured the bass was not tubby any longer. The 204's bottom end is as good as the Krell, maybe better. The resolution from zero feedback amps is astounding.
The 203 and 4 are hybrid amps. Fully Class A input with A/B output stage. I'm under the impression that they don't output Class A at all. They don't run as hot as the Krell's did, but they can heat the room. I love my MSB stuff. A friend tried a panorama of my room, looks interesting. View attachment IMG_2574.jpg
 
Welcome to the forum, thank you for joining. Beautiful room and setup you have, thank you.
