WHich is?? Is it posted somewhere or in Stereophile? I don't have a subscription...
The darTZeel??? Surely you are joking...
Stereophile: http://www.stereophile.com/content/dartzeel-nhb-108-model-one-power-amplifier-measurements#uBJ9SibqxZT4kuOl.97
Let's have a look at those measurements shall we?
It has the same distortion at low power as at high power...usually not a great sign
It does have flat distortion vs. frequency...a good sign
However, the distortion at 50 hz shows a picket fence of harmonics...not promising
Soundstage:
"http://www.soundstagenetwork.com/measurements/dartzeel_nhb108_model_one/"
Good THD vs. frequency and evenness of damping factor
But look at CHart 5 at the harmonic distortion at 10 watts at 1Khz...Yikes!!!
Definitely not monotonic and almost certainly audible..
What we don't get from either review though is the IMD harmonics but I think we can guess they are not so good.
Have you heard the Dartzeel's ? from the bench it has too small a PSU for me to give it the full NOD, but it is highly rated and accepted for it's sonics and exhibits good tendency' if used above 4 ohms. speaking of , I'm sure you did not miss the squarewave of the LAMM at 10K , plenty slewing, not as good as the dartzeel, will make bright speakers sound darling.
Yeah , not as straight forward as the charts would suggest..

As stated above, I heard them in the designer's home system. I also saw them being assembled in their workshop and heard them and the big daddy one at a few shows besides.
I won't agree with JM on this or many of his picks for that matter (his recent endorsement of the Wilson Benesch speakers, for example).
Thank you I am checking it out now, it does look pretty nice.
One issue I see right away is that it is $18,000 which kinda raised my eyebrows.
Seems like an awful lot to spend just to almost sound like tubes?
