Hmm.. I understand the concept of so called "high end portables" but I also do agree that they are fairly overhyped and overstated in what they can do. In the contexty for what they wrere desgined for, they do a good job (decent quality for listening on the go/away from home, etc..). However I also do agree that the ability of these portables are overstated, by a fairly large degree. All you have to do is look at whatthey are desgined to do and whatthey have to play with. You need a small packge that gives good sound and decent battery life. Somewhere in there, sacrfices can and will be made. Invariably in a portable aplication battery ife is a huge factor and from where I stand, the largest barrier. I mean I'm sure that it could be done where the portables compare or even prove to be sueprior to home amps in their price range, but given that battery life is alwaysd a concern as well as size (and it should be), that is the key sacrifice that has bee n made. And IMO, if you actuaLly compared a "home amp" with a portable amp in it's price bracket the limitations of the portable would be clearly evident, and the limitations of the stationary solution being fairly obvious. That being said, true "home amps" don't even begin until atleast $150 or so with many of the comparisons for home amps coming at the $300+ pricepoint in the portable segment which is in fact only a few products. Another key is how you evaluate it. If you evaluate both units ars so called "home" amps, then it would be more evident to see the defficIencies of the portable unit than the home, which is the comparison that is otentimes made (___ portable amp compares very well to home amps in it's price range).
So yes whiel I do feel that they have come quite a ways forward, I also think that they have quitea ways to go if they want to truly compete with home amps in theiir respective price brackets if there are any at all.
