impressed with himself and nary mentions actually listening to music. It's all about the numbers and lots of *fixing* the signal after the fact. He hasn't changed.

Funny he praises for Halcro for its measurements. That's one brand Harry Pearson declined to review because of its poor sound quality. I remember seeing a pair of DM-88s at Sea Cliff and asked why they weren't hooked up at the time. The eval was very short.

By contrast, my core "sensibility" is with the listening - not bowing to non-correlated metrics such as SINAD.

Worship whichever you please. ;)

He does mention listening in a different article he wrote about feedback.

He mentions it in this one too but is more subtle about it. The measurement people take even him to task on that, ironic because he also makes the lowest distortion amps around.

  anyone care? I've owned an Ncore amp before.
  
  Geddes has demonstrated lack of correlation with that metric.

    I've maintained something similar.
    
    The NCore like other modules, is sold as a module only. It makes a really big difference what power supply is used (and if it works properly) as well as the input buffer. If those things weren't nailed down properly you might not have heard what the NCore can do.
    
    That is we did our own module in our class D, so we could control all the variables. I play a set in my own system and don't miss the tube amps.

      I had a couple NCore based amps here in my listening setup. They were all the rage and often put on a pedestal above ICEpower. Funny thing though. My ICEpower amps all sounded much better to me. My last ICEpower amps were the PS Audio M700 monoblocks which I thought were excellent. I am now running a Class D amp based on the Purifi Eigentakt design. It's ever so slightly more refined but the ICEpower M700's were still outstanding.

I did warn it might be triggering. He writes about designing for good sound but the implication is that it goes hand-in-hand with exemplary measurements. Who is right and does it even matter? I find it a great irony that audiophiles are all about the sound over measurements and yet all reviews and sales pitches are about the underlying technology (or, at least, the Brownian stirring of the audiophile soup) and the punters ally themselves with technologies they like and take against technologies they don't.

As for worship, I think that best left for the faith-based, the name-droppers and the math-shy charasmatics :)

Maybe there is some common ground - do you agree with him that vinyl is not superior to digital?
- Nah - E-Stat 15:25:28 10/27/24 (0)
  just the same ol' same 'ol like interviews he's given over the years. Nothing new here.

  Define digital. It's most certainly not a single *thing*.
