Class D


Been thinking of trying a D amp to reduce clutter. Most that I see are not rated at 2 ohms.  My PSB Stratus gold's will drop to 3 ohms or lower at some frequencies. So my question is will these types of amps handle this impedance ?
Thanks in advance. Chris

It does seem the Mola Molas were overhyped, or the reviewers connected them to more efficient speakers, proper impedance matched preamps... but in the real world, they are likely cabled with impedance mismatched preamps, or hard to drive speakers, or...


I have used quite a few different Mfgs class D amps over a decade, none came close to the EVS1200 of TweakAudio.com. based on dual mono IcePower AS1200 modules that he then sprinkles decades of moding know how pixie dust. Needless to say, they are powerful, especially with my 96dB Emerald Physics Open Baffle 3.4s + 2 SVS powered subs.


Unfortunately (for the rest) he is no longer making the EVS1200. PS Audio has the M1200s with tube buffer, but none of EVS’s magic and a hefty $6000 price tag, though it's a pittance compared to the Molas. Im not suggesting the M1200s are superior, but for rockers, probably. Last night I listened to the MoFi SACD of Dire Straits Love Over Gold. The SVS 12" subs were the weak link

It's not an integrated but the March Audio P502 stereo amp is rated to 2 ohms. Sounds very good with Revel speakers. If you're looking for silly tweaks that either do nothing or degrade the amp look elsewhere this guy doesn't buy into the voodoo just gives a great performing amp for a decent price.
I have Classe Sigma Amps - they sounded exceptional, but they could not drive the bass on my Wilsons.  I had other amps go into protection at concert levels (Bryston / PS Audio).  I moved the class D's to surround duty and put Rowland Monoblocks in to drive the Wilson load which can dip to 1 ohm.  Pure bliss.

Well, not that I’m aware of what you suggest, as his review speaker were SIBELIUS of 87 dB.
Those Mola Mola monos are supposed to ’do’ some 400 odd watt/channel (into 4 ohm...) - somewhat more than my X350.5 Pass.
So - no go with my power saving notions.
This issue is/was some often mentioned with class D amps, and can strip music of its musicality. 
Was happy to go back to my present set up.

My 4 ohm Apogee Duettas were driven very nicely by a pair of Bel Canto Ref 1000 monoblocks. I'm sure they would work fot you Zappas.
