news from Allo.. They are making another amp 100 watt/ch soon.. the time limit they mentioned is around 3 months...it really made me feel excited....i read it in another forum...
I do not expect that to happen due to cost, bulk, and weight. I'd expect instead an appropriate implementation of a capacitance multiplier as in the Volt+D.I will be very glad if they include a transformer in the design and skip switching power supply ....

I agree, they would be shooting themselves in the foot. Except that a cap multiplier is mostly good for DC smoothing, and 32xx are already pretty good at rejecting supply ripple from a reasonably well executed SMPS, so for me a CM is much less necessary than putting enough real capacitance on board the amp.I do not expect that to happen due to cost, bulk, and weight.

What do you guys think of this?

Not exactly, but the same general idea applies.would this procedure work the same for tpa32xx?
One reason would be that the chip is best configured in PBTL mode (mono output, see the TI datasheet for TPA3110). If you get a board that can be set up for PBTL that would be a much better solution.I am thinking about building a mono open baffle Bluetooth speaker based on a TPA3110 with Bluetooth board. Is there any reason why I could not connect both outputs to a single (8 Ohm) speaker?

There are other mono boards on eBay but this is one I pulled up first.
