As many folks have said, there's more to an amp that just WPC.
Although I have listened to music via digital since early 1984 when I bought a Sony 610-ES CD player, I'm pretty old school when it comes
to power amps. I've owned 2 sets of Class A amps and still have 2 Class A mono-blocks.
Outside of the proprietary circuit designs, Class A & A/B amps have 3 components that go a long way to defining their performance\capabilities.
Big transformers, lots of capacitance & lots of high quality transistors.
Certainly digital music recording, mastering and playback have come a looong way since 1984.
Many early players and cds didn't sound as good as a high-end TT, Cart, Phono section & pristine record.
It seems that "Digital" amps are in that same technology learning curve.
In reality, the technology in a SS amp is really mature. The question of sound quality & capability basically comes down to a question of cost to manufacture.
Certain mass-market audio companies make uber high-end pieces of gear. The question isn't one of technical knowledge but of target market.
Will a digital amp sound really good for the first week or 2 and then will I start to miss certain things or hear undesirable "additions"?
It was the same way for me with CD early on. In some ways I didn't care about any possible loss of fidelity because I was really tired of F'ing around with vinyl
as a format and it's inherent limitations. CDs were far more convenient and flexible plus you play an entire album without interruption and CDs don't degrade with repeated playings.
I know I love the sound of a well-designed Class A or A\B solid state amp and I have some trepidation about whether I'll like these NCore based amps as much as I do SS amps.
Why I was so interested in Kal's review is because I trust that wouldn't be willing to give up any loss of performance regardless of the amp's weight.
Dave's review will only ease my qualms, at least I hope so.
I'm far more familiar with Kal's writings and tend to agree with him on subjects where I have the same knowledge\experience.
Really sorry for the long explanation. I got carried away.
Bottom line, I know I like SS amps, I don't know if I will be as happy with Class D.
