What a load of marketing rubbish!

All they have done is make a 'DAC with enough power output to drive speakers' so surely still has a power amplifier stage as it would be crazy for a DAC chip to have power amplifier stage in it aswell. Maybe it even has a preamplifier stage aswell haha. By the sounds of it they have used class D (Not digital) amplification as it has a 60khz low pass filter. All they have done is put everything in one box and pretend it is some kind of innovation.

The whole 100% digital thing is misinformed. Music/Audio is an analogue signal, no changing that so if it is converted to digital data (great way to losslessly transport data it must then be converted back to analogue so it can be heard). Nobody would want to listen to a digital signal through their speakers.

No doubt its a nice sounding amp but there is no new technology here

Whoa that really jumped out in my office.This weeks system is a Lepai 20 buck amp on Klipsch sb2 and a TAT with a plate amp. Nice recording as usual R, how would you compare the 2?

Certainly, I was already late to the party when I started this thread. Tardiness was the source of my frustration. The tech was developed in the mid 90's and patented in '97....trickled down to the consumer-level gear by 2001.

Well, what's to expect when you try condense this into a one paragraph sales pitch? Not only is their website horribly dated as well, but a savvy person is going to cut through anything the sales department has to say anyhow.

Didn't notice any audible difference between the two. Specs say they have the same ratings. The 700 is definitely sexier to look at, has all gold-plated connectors (which I don't use), and an auto-setup feature (which I also don't use). Interestingly the 57 has a nicer feel to the knobs when you turn them. I'm sure there's a few tweaks inside, but I'd have to see the guts of each side by side to be sure. I paid the same price for either one...~$270 with shipping figured in.
