Removing a ZERO from the price of amps

I mentioned a quote from Bruno on Computer Audiophile interview about a year ago saying the goal of Purifi is to remove a ZERO from the price of amps. Sounded very exciting a year ago and we are now getting close to getting this out to consumers.

A Benchmark AHB2 and one of these Purifi amps for me please.

Wondering if the A1’s big, weighty sound had anything to do with the huge and hugely expensive Constellation Revelation Taurus monoblocks, I switched to the Purifi evaluation amp, which offers less than half the power: 200Wpc into 8 ohms.

Thank you for the interest in our class-d amplifier technology.

There is a thread on audiosceincereview listing possible suppliers:

I listened to the first part of Bruno’s interview. There is some truth to what he is saying........but, tons of things that affect sound cannot be measured. For instance, I just changed 4 inches of Hypex cable on the input of a Purifi based amp I have here to my own custom cable. The sound difference is huge, but the amp would not measure any different. Nord and Apollon claim their (not quite as good measuring) NC1200 based amps sound better than their Purifi based amps. A guy on Whats Best Forum has two amps from Nord done pretty much the same way.....one set of monos with the Purifi and the other with the NC500s.....he does say the Purifi is a little better but whatever op amp you put into the modules makes way more difference than the modules......and I bet swapping the input wire would be the same.

A great measuring amp is a good place to start.....but every Purifi based amp will sound different....because everyone will use different jacks, wire, solder, input stages, regulators for the input stages....passive parts in circuit, layout, AC jacks, fusing, etc....to infinity.

I am finishing up mods to Purifi based amps, right now. A part of my mod is to modify the Purifi module. No one has ever modded an NCore or Purifi module to my knowledge....they just add their own input stage. There are parts on the Ncore and Purifi modules that add audible distortion (not measurable). Putting lower audible distortion parts (and execution) here changes the sound to a more detailed and real sound. I will have more info shortly.....with very explicit details.
