From a marketing point of view, I'd go for the completed amps based on the 100W/200W boards. Reason being the market is already flooded with completed TA2024 and LM1875 etc amps, while few completed TK2050/TAS5615 amps are available and those available are either too expensive or too cheaply built. Also I feel that some people want to try these newer high-powered class-D amp kits (both yours and others') but don't have the ability to DIY them so there is a market for the completed amp.

Only you would know this though; if your completed TA2024 amp or the amp PCBs sold better on eBay. If the completed amp did not sell better, then forget what I just wrote.

I really like the 1x100W option!
And a new suggestion would be using the STA517B instead, so you can deliver up to 200W!! (direct replacement with the TK2050, only a few modifications needed)

I also like the 2x50W option

What would be the price for the volume control? (and can they be stacked for control more channels, like 5.1 surround)

Maybe a volume control with source selector would also be great 😀

Maybe you can use a bigger passive cooling block (like the coolers from Zalman) for the 2x100W amplifier.

I guess all people here want more power for their amplifiers, but i would like to see some slight mods to the existing tk2050 boards (the non-4 channel boards).
Please remove the limiters underneath the boards, and exchange the ceramic input cap for something with film/foil in it, maybe even the polyester caps that come with the 4 channel boards?

Would also like to vote for a sta517b board, but this requires some more changes to the board, as most traces have to be larger, and bigger output coils are needed.

I vote for a high power completed TK2050 based amp (actually TC2000 + STA517B) with good / high quality critical parts (input caps, output inductors, volume pot), adequate passive cooling and decent inbuilt SMPS. That would be my favorite! 🙂

I vote for the 2x200W module, as well as for the 2x100W and 2x50W ready built amps.


And then I vote for a 4x50W ready built,
<wishlist>
but that I would only buy, if you supply it with an active x-over, so one could create an awesome Sub/Sat or FAST system!

And that X-over of course has three inputs, so one wouldn't need to plug around the inputs. Edit2: The x-over doesnt have to be anything fancy, maybe even adjustable only via changing components, or hardwired for say 50/100/200/300/400Hz xo point.
</wishlist>

Edit: and definitely sell kits with PSUs!

Mmm I missed the 2x50W amp while reading.

1 TP2050 for $35 vs 2 TP2050s for $45.

A single TP2050 in stereo mode (for 2x50W) is not capable of 4 ohm load according to the datasheet (6 ohm minimum), is 2x50W @ 8 ohm not 4 ohm, might want to take note of that.

I'd love to see a predrilled case big enough for a board plus the meanwell PSU. Since the higher power boards and the meanwell PSUs have the same form factor customers can mix and match while you only need to stock one case.

If shipping becomes a killer however, then it'd be nice if you can be a source for external PSUs. Like this SINPRO SPU-130 that Virtue Audio uses.
