Help me understand the differences.
 
OK short of part quality help me understand the differences of say a Sure TAS5630 amp and a Sinewave Electronics unit. Price for a Sure unit with 36V power supply is about $80 shipped. Price for a Sinewave unit is about $200 shipped. Explain to me why the stark contrast in pricing. Once again short of part quality what makes then stand apart from one another?

To which Sinewave Electronics unit are you comparing the Sure TAS5630?

G300V21 also a TAS5630 driven unit. The Sinewave also has I believe a 48 or 50V supply.

From: Sinewave Electronics Co.,Limited Sinewave electronics co.,limited

"Sinewave have good experience in SMPS and high frequency switch amplifier,we develop the first SMPS and TAS5630 chip all in one board in the world,..."

But besides that the Sinewave is on a nice (IMO) box, ready to go.

That has to count for something.

How big of a box would you need for the "...Sure unit with 36V power supply..."?

Beyond that how does the performance of each compare...compare apples to apples and see if there is any difference...you mentioned 50V vs 36V...what else is there?

Erm ..they are Both Chinee. Good luck with either.:rolleyes:

Well apparently the Sinewave G300V21 boards ($180 without enclosure) are very good, about the same price as a ClassDAudio board but with integrated SM power supply. Although they don't allow Balanced input as the ClassDaudio units do they a much more cost effective. I'd love to do the TAS5630 unit from ClassDaudio which allows for balanced input but with a SMPS they would be substantially more expensive than the Sinewave.
