Class D ICEpower 1200as2 vs. Purifi 1ET7040SA amplifiers

Greetings,

Has anyone compared the ICEpower 1200as2 vs. Purifi 1ET7040SA amplifier in their hifi setup?  Legacy Audio uses the ICEpower module in their i-V2 Ultra and Doug Schroeder did a nice review on it.  I first read about the i-V2 Ultra in Doug's review on the Pure Audio Project Trio15/Coax10 review.  I just ordered these speakers, so I am interested in this amp.  I researched a myriad of class D amps and I've narrowed down my interest to the following; GaNFet (AGD Audion), Purifi (Apollon w/Sparkos opamp), MOSFET (Bel Canto REF601M) and ICEPower (Legacy Audio I-V2 Ultra). 

 

I know ICEpower modules are older class D technology, but if they are equal or outperform the latest offerings, that's all that matters to me.  Plus, I understand they are reliable as they have been around for a long time. 

 

I owned PS Audio's M700's and S300 amps which use ICEPower modules and they sounded really good, but I sold them several years ago to explore the world of tubes.  I'm back to solid state now and interested in the latest class D offerings.

 

Any impressions/experience with the icepower 1200as2 vs. Purifi 1ET7040SA amplifiers are welcomed.  I've already read good reviews on both of them, so a comparison between the two would be most helpful.  In addition, let me know if you have compared any of the class D amps in my list in the first paragraph.  I understand I need to hear them for myself, but I still appreciate your opinions!

 

Thanks in advance

The horn loaded HF driver in the X5 is really good, just the vertical dispersion issues. The Pure Audio speakers look interesting. Bet the dispersion is excellent with the mid/HF concentric driver you got with a larger sweet spot. 

One thing I should mention is the Pass XA25 with the X5 was truly magical.

And I second the Atma-Sphere GaN monos. Definitely worth an audition. I did audition them (twice!), and I might still revisit that decision.

First, the LSA was way too much power for my situation. It is a bit warmer than the AGDs, a little less detailed and refined throughout the range, less transparent. But still a very good amp in my estimation, especially given the price.

@lewinskih01 Yes, a speaker manufacturer did recommend Atmasphere class D amps sometime ago.  I’ve had PS Audio M700 monos, S300 in a second system, Prima Luna EVO 400 preamp and amp combo, then moved on to the Luxman L-509x integrated.  I sold all of them and using a HEGEL H160 integrated from my second system until I decide on another amp.

 

@markmuse I do believe the PAP 10” coax driver will be the ticket, so I’m looking forward to hearing them.  So, you are still contemplating pursuing the Atmasphere monos to possibly replace your AGD amps?  If so, what do you feel the Atmasphere does better?

 

Thanks

Wish I could say. Last time I had the Atma-Sphere's here I still hadn't a decent pair of hearing aids. Got that fixed now - Widex: best audio system upgrade to date!

@markmuse 🤣 That was funny!!!  I understand that.  The ears have to be ready to receive the signal to properly judge it.  
 

Let me know if you get the Atmasphere amps in house to do a shootout with the AGDs.
