If we are going to diverge on this thread about Purefi. I will add that Computer Audiophile has a great interview with the Purefi team. The thing that caught my eye was Bruno's quote that the goal of the company was too to remove a zero from the price of an amp. If his amp were to compete against a $10K amp he wants to build it for $1K (just arbitrary numbers used by me).

I looked a the NAD M33 Purefi amp via the specs and was a disappointed it does so many things in 1 box. Not really the dragon slayer amp that Bruno was talking about in the interview. Though this is the first amp to have the new Purefi tech so I am still waiting on a Purifi amp only, something like the Mola Mola Kaluga amp.
