My tweaky side awakes...

Nad is constructed by a Nordic dude called Bjorn Edvardsen. (BEE = Bjorn Erik Edvardsen..)
He has chosen very early on to use a "jumper" between the pre and amp parts of his integrated amps.
One can subtly alter the sound, and even improve upon the sound of these medium size integrated.
What you do is that you replace the "metal" jumper with a very small RCA-RCA jumper signal cable.
I've had great success with Audioquest silver types for this kind of use.
I would also assume that a very short Jena labs jumper would work as well, with a bit more oomph to the sound.
A Nad C372 with a properly chosen "jumper" is a small dynamo of an amp!!!! With the standard jumper in place you loose just a bit
of the "air" this type of amp can convey. A presentation that in some instances can be beneficial.
I believe not since the Nad 3020, a Nad amp (C372) has been received so well (Apart from the Nad M3 of course..) by those who also have heard the 3020... it is indeed a sweetspot in the Nad line!
The Nad C372 have had a revision to it's powersupply so there are two versions of it: V1 and V2.. You WANT the V2 type!!
The poweramp only type of this Nad is called C272, it also has had a powersupply revision.
The Nads are SILENT running, producing NO noise even into a 105db sensitive speaker...
But... and I would recommend doing this, Nad has a "tweaked" version called the NAD C 375BEE... it is a marvel of an integrated.
Get the NAD C 375BEE! It simply is a better amp! $1299 I believe is the list for it. (The poweramp 'only' version is called C 275BEE.
