The End Of Big Iron?

@Mapman, it's interesting that you mention not going back from Class D, including to tube amps.

In addition to the Peachtree Grand, I have an ARC VSi55 that I run in the winter when the heat isn't an issue here in AZ, and I swap them out between my two rooms just for fun. I consider the ARC to be a nice amp, nice sound, nothing to sneeze at. And we've done just casual A/B tests between the Peachtree and the ARC, and at measured equal sound levels I honestly can't tell them apart. They sound equally enjoyable, except that the Peachtree can play much louder effortlessly. Which sort of highlights how far Class D has come...you get tons of power, in a nice footprint, low weight, without all the heat, and at least in my case it just happens to sound as sweet and balanced as my Audio Research tube amp.

Manley NEO 250s that I use certainly have some big iron in them and they sound better than the Krell 400cx they replaced.

Big iron....more than 100lbs??....140lbs??

I love big iron and if your going to leave it on 24/7 because some sales manager says to ..then pay the power $$$$

I love big speakers (and I dont mean girly ones like Wilson's maxx or Peak Consultant. .etc)
To me anything less than twin 15" per speaker(ATC 300..Rockport Arrakis..etc) is not big...l use the Maxx as a example because of their drivers not cabinet.
A Krell fpb 600/700 will make those big boys dance..
I believe that double the woofer power is the best...
For example. .if you have 2 fifteen inch rated at 400w each at 8ohms which equals 800w at 8ohms then I want 1600w at 4ohms so that the headroom equation comes into play...this means BIG IRON..

Unless you are active

I have a fully recapped (214 caps)Krell FPB 600 and a 700cx that are in mint shape and only need one ...cash pickup or shipping in Canada only..
THESE ARE BIG IRON..
These actually will almost put out 1000w/ch
The rest are Mark Levinson. .ML 333...332..331..&..335
