I would like to try the TAS5548/TAS5631B amplifier, please let me know cost and delivery details to New Zealand.
I already have PurePath Console on my computer, and I also have a TAS5548EVM.

Thanks!

G300V31: 500W SMPS+ Tas5630B or TAS5613A

I appreciate the input. Please understand that my review is for the older G300V21 module, not the newer G300V30 or G300V31 boards. I will need to listen to one of the newer boards to comment on how they sound. My G200 amplifier was electrically grounded to the same ground connection as my preamp and CD player.

I will be in contact with you soon about how to order a G300V31 board with TAS5613A.

Another area where Sinewave could improve their product line is to offer the SMPS and the amplifier section as separate modules, which could be combined by amplifier designers in a single chassis as needed. The modules could be available in stereo and PBTL mono configurations to suit a wide array of applications. This is similar to what is currently offered by Hypex
I cannot agree more with your statement here! I think they would sell even more of their boards this way
I think the following complement of modular products based on TAS5613/TAS5630 would perform very well in the market:

500W Audio SMPS board: Same SMPS as currently on the board for G300V31, for driving one stereo or one PBTL amplifier module.

1200W Audio SMPS board: For driving two TAS5630B-PBTL amplifier modules (providing 600W each), or one TAS5630B stereo amplifier module where extreme high current is needed for improved bass.

600W Linear Audio PSU board: Linear power supply for use with 600VA transformer of proper secondary voltage to supply power to amp modules - includes rectifier bridge, filtering capacitors, and reservoir capacitors for driving one TAS5613A stereo module, one TAS5630B stereo module, or one TAS5630-PBTL mono module.

TAS5613A Stereo Amp Module (No PSU): Component selection same as the amplifier section of the G300V31 board but with TAS5613A chip - requires external PSU

TAS5630B Stereo Amp Module (No PSU): Component selection same as amplifier section of the G300V31 board but with TAS5630B chip - requires external PSU

TAS5630B-PBTL Mono Amp Module (No PSU): Component selection same as amplifier section of the G300V31 board but with TAS5630 chip configured for PBTL - requires external PSU

Provide 0.250 fast-on connections between boards for DC power and speaker output, not molex type - this will make the products easier to use for DIY customers, while industrial customers can still use them easily. My big complaint with the ICEpower boards is that I can't assemble the wire harness connectors, so the way Sinewave currently does it is better. I also prefer the way the heatsink is an aluminum plate on the bottom of the Sinewave modules so they can be mounted to any aluminum surface for heat transfer. This seems like the best way to provide the needed heat transfer for the SMPS and the TAS5630 chip. It is a good, smart design.

That is how I think a line of modular amplifier components could be set up. These modular products should be offered together with the existing complete G300V31 modules to allow amp designers to create the solution that their project needs by combining modules.

Does it support USB audio input from PC, or is it just USB programming - I think both is said in the text, so I'm a bit confused.
