Got the latest copy of Sony PULSE today, and saw these rather more subtle 'Stream Regnum' amplifiers, boasting among other things:

* Larger choke coils
* Toriodal's with lower electro-flux in the final amplification stage for flawless sound
* Better mounting and heat distribution
* Multiple methods for reducing vibration

So, I was wondering how these classier looking amps compare to the old Sony ES series, is this an SQ lineup, like Sony was once famous for?
Or just a re-hash of the XPLOD series?

I'm intrigued. Industry experts, what's the go?

Searched and no matches!!

Details on the sony site... look at the nice grey ones on the side bar not the red things.

considering they have "XPLOD" written on them, i would hazard the guess and say they are just a new season range of xplod gear.
yes they do look more attractive, not as brash as the older red ones.
the power outputs seem impressive too (eg. 2x200wrms/1x500wrms), but then again, it would make marketing sense to release the higher powered models first.
i think the best thing to do is sit, and wait for some feedback about how they compare to the older ones

same model number but on sony australia site no mention of the "STREAM REGNUM" whatever that may be.

anyway those new amps actually look nice

not to bad in the power department either

"Toriodal's with lower electro-flux in the final amplification stage for flawless sound"

Whats a toroid doing in the amp stage? Unless the marketing department has got onto this. Low flux as well, yeah i guess they have

class D use torroids in the output (not as tranformers) just as the formers for the LPF (RL circuit) - but yeah marketing at its best

The XMSD46X and XMSD-51X will be reviewed in the next issue of Auto Salon magazine versus equivalent amps from Coustic, Kenwood and Fusion. I think you'll find the XSMD61X will be featured in the rehashed Car Stereo Australia too, but this will be a few months off yet I think.

Same **** different stink by the looks.

the monoblock cost like $800, should be good right?

They are lovely looking amps, I have a couple on hand.

Must admit I haven't pulled one appart yet, might do it over the weekend...

Arghhhh they're hideous and filled with marketing bollocks - ya for sony.

Started to pull one apart and lost interest when I found there was about 500 screws to take the PCB out to get a decent look at the components... :s

heehee want me to scan the two small Pics from the Sony catalogue?

Updated first post to include the scans (i actually just stole em from the online catalogue :wink: )
