With the $16 Trillion stolen by the elite bankers who brought you "The Fed", over 110,000,000 music loving audiophiles could have a pair of these monoblocks!  OR, the world could be housed and starvation ended AND have enough money left over for as many monoblocks as there are people who would want them.

Or you could do something about the "conspiracy" to take land from Native Americans by giving up your home to a nice Navajo family.

rubbish output impedance and too much harmonics for something this price. garbage.

Moments ago, I visited the DartZeel website and discovered it reveals about as much technical information about this thing as this review did -zilch.

What's with this half-baked review ?

Is it (468 mono's) a A/B or 'D' design (output stage) ?

And what adolescent designed this computer-tower ? At least that would be out of the way - and credit duly noted.

I suppose it should be no surprise that the Swiss jump onto the scene when the dollar/value has little relevance.

Soulution, DartZeel -really ?

Why not consider ML or Pass Labs, Spectral, perhaps SimAudio (previous Classe product) ... in fact the list can go on (VTL, Bryston -amps) and on.

Audiophile ALL know system integration is key to great sound; we know full well the DartZeel amp's subjective performance can be skewed/jeopardized by a any number of factors. And similarly, less expensive products' sound can be enhanced (or held-back) by similar considerations.

The point being, either way you flip it/look at it, the same type of performance can be observed either way. In which case, offerings from well-known, established brands from USA/Canada would serve the audiophile just as well -if not better. With local support.

I know where Id put my money, energy and passion.
