Oh how I wish Class D amps ...

Keep in mind that audiofreakgeek is a Nuforce dealer and his comments must be taken in that context.

A dealer disclosure is essential when discussing products in which there is financial interest.

Nobody has mentioned the NAD M2,anyone had a listen to this one?

"Nobody has mentioned the NAD M2,anyone had a listen to this one?"

No but it is on my want to hear list.

Realize that this is a true digital integrated that includes a Class D power amp and is all digital in front of that (except for analogue inputs that are converted to digital internally). So this is a slightly different but related beast.

How about the ARC DS225 or 450?

Hello Kijanki,

"It is often said that Icepower sounds good only with linear power supplies. On the other hand newest linear class AB amps from Jeff Rowland (one costing $46k) use switching power supplies. "

You are correct, Jeff Rowland developed his own highly regulated switching power supplies with PFC and show that this power supplies is the future for class A or A/B, ss and tube amplifiers.

We also have developed in 2008, very powerful swtiching power supplies with PFC abd fully regulated but we use it in our pro audio projects only as price/benefit analyses of moving it to Musician III with its linear power supplies show relatively little sonic benefits versus substantial price increase to cover the transition.

Refarding all other switching power supplies I am aware of - some like NuForce in their Ref 18 amplifier started to add electrolitic energy storage capacitors, This, if done right, should substantially improve current delivery and peak power delivery which in turn should improve sound.
