Is D for Dry? Class D...

I have a pair of PS Audio Trio A-100's that I've upgraded by removing the 15 year old B&O ICE Modules and replacing them with current 2021 revisions of the same 200ASC modules. So, kind of a frankenstein amp because this mix of parts never existed "in the wild". In any event, they sound amazing. I use them to bi-amp my speakers for summer listening, because my Pass Labs X5 is just too hot to use in my small listening room in the summer, in Arizona. 

I have never seen or modded a Rouge or PS Audio amp. However, they will both benefit the same from the mods. I spent 6 months modding the IceEdge module so this is why I know my mods will work. Tonal differences? Way more to sound than tonal differences. Maybe you mean sonic benefits? Please call me if you want more info. Now back to your regular program.

No, you can clearly see the stereo IceEdge modules in ALL of Legacy’s amps. They do not use the AS1. Buying AS2s in bulk makes more sense, since they make a lot of multichannel amps.

"Sorry Zephyr, my comments were not meant as an insult or disrespect, and if you took it that way, I apologize.

I’m biased towards Wilson Audio speakers, and my feelings are the same as yours in regards to other manufactures. However, bias does play a big part in anyone’s purchasing decision."

@golfnutz  I did not take it in either of those ways at all so no worries and thank you for your post.  I only took the implication that my positive comments on the amp after 12 months of hearing it and knowing exactly what it can do in the context of how I've implemented it including cables, speakers, etc...were drawn primarily from brand affinity.  Believe me, brand affinity does not overrule what my ears are looking for to the extent that I would misinterpret or misreport the results just because the folks at Legacy take fantastic care of their customers in all the many years since my first purchase back in the early 2000s...

Definitely agree with @ricevs here based upon all I've been told or seen with the cover off the amp;  the modules in mine are definitely 1200AS2's used 1 per channel no a 4-channel amp.

Ricevs: Still keen to know (via IM or a website) what mods you offer as I was sincere in my prior post about investigating them and assuming they won't cross with anything already done in the amp design by Legacy or void warranty considering them seriously.

If you want to know anything about my mods then please call me.  Any mod done to an IceEdge module will void all warranties with the manufacturer (Legacy, in your case)  and with IcePower.  This is one reason most would not be interested in mods to expensive gear, like the Legacy.  The modded Rouge Design would cost you very little.....the IceEdge modules (modded or stock) are super reliable.  All 12 of my modded amps from 2019 are still going strong.
