Okay I really hate to respond but, Nuforce is not a bad amp at all... It is for the people that are "Intellectual" or more of an accurate listener not the super emotional listener. They do everything well and maybe perfect, but music is not perfect and maybe should not be... Big reason tubes are very popular is they add a certain harmonic distortion or color of their own to give a certain conveyed sound, same as Vinyl to CD in some extent... Nuforce does not sound fatiguing or any of the bad words that solid state carries with it most of the time, but they are not for me in the end.
If you like a "wetter" or more liquid organic sound and do not mind that the hard edged definition is missing in your music then these are for you, and they are super efficient very small and well I guess cost effective in many ways, but not really..
Bottom line is sure you can get some real crap between 1500 and 3000.00 dollars, and some Gems, and these might be better than what you have or heard no doubt...
Here is the problem with these in my eyes as a bottom line, and this was verified to me by a couple of very good amp manufacturers and I am no expert, there is no more than 150.00 worth of parts in these, No big Caps, No big Torroids, No big fancy Cabinet which is the main costs on any amp and they went on to say they could easily copy the design and have no problem admitting they could beat out some pretty good competition.. So yes these Defy all odds and Can sound good doing it, but remember FACTS are Facts you will be buying 3 lbs of very basic design and a couple of fancy WBT posts for the money that you would in turn be putting into actual electrical components of actual cost buying better A/B or tube amps that have actual value in parts inside.
IN NO WAY am I saying this effects sound, Right or wrong but this is something to think about... If they were about HALF the price they are then I could choke down the fact you are buying next to nothing in simplicity and good sound for a simple and versitile component. IF you really do the math guys, look at a 1000watt digital Plate amp, you can have them for what a mere 150.00 retail these days? thats because parts are very basic and efficient in these designs.
I would go for them in a 7 channel setup or something if they ran about 250.00 a piece, but even then I just heard the New JVC hybrid receiver and it does all channels digital for about 450.00 with processors and good sound.
For 2 channel they do not do it for me, I have heard them in a couple systems, so again they could be better for others and synergy could click with other stuff.
My money is not going to them and on first impression they present music in a way that you may not be used to hearing in a conventional manner and you may reject them immediatly, but always try them yourself, opinions and reviews mean nothing next to your own needs and ear.
